Description

  The present invention relates to a packing material for packing an article.

2. Description of the Related Art Conventionally, a storage case assembled from a corrugated sheet has been widely used as a packing material for packing articles. However, just storing the item in the storage case may cause damage due to the displacement of the item during transportation. For this reason, packing an article using a packing material which has a buffer function is also performed.
For example, Patent Document 1 has a base board and a restraining sheet, and the base board is a rectangular plate divided into an article mounting surface, a falling portion, a rising portion, and a support portion. The article mounting surface is a surface for mounting the packaged article secured in the central region of the baseboard, the falling portion is a portion which folds back both side edges of the article mounting surface by a constant width, and the rising portion is It is a part which turns up both ends of the article mounting surface upwards with a certain width, and the support part is the four corners of the baseboard where the falling part and the rising part intersect, rising with the falling part downward When the part is folded upwards, it is folded in intimate contact with the outer surface of the rising part, and the falling part is held in a downward posture as a leg of the baseboard, and the restraining sheet has at least both ends compatible with the baseboard. Fixed to the lower edge Covering the surface of the article on the base board, the folding of the trailing portion, tension to press the article to the base board, packaging materials for holding this by preventing the lateral displacement of the article in position is disclosed.

The packaging material of patent document 1 can package an article in the following procedures. The downward portion is folded upward to open between the baseboard and the presser sheet, and an article is inserted between the baseboard and the presser sheet. Next, the compatible downward portion is bent downward against the tension of the restraining sheet. Furthermore, the rising portions at both ends are bent at a right angle upward to the article mounting surface of the base board. In this way, articles can be held on the baseboard and the presser sheet.
The packaging material holding the articles between the presser sheet and the baseboard has the rising portions and the falling portions on the four sides of the base sheet, and is transported in the outer box.

  However, the packaging material of Patent Document 1 is premised to be put in an outer case, and the degree of freedom of packaging is limited. Specifically, the packaging material of Patent Document 1 prevents folding of rising portions and falling portions folded in four directions of the base sheet by storing the packaging material in the outer case, and in fact, the outer case It will be difficult to use if it is not stored in the For this reason, in using the packaging material of patent document 1, it is necessary to prepare the outer case which adapts to it. Therefore, not only packaging costs increase, but the articles can be packaged in only one packaging form.

And an extensible sheet 124 (hereinafter referred to as a second extensible sheet 124).

<First packaging material>
With reference to FIGS. 1 to 5, the first substrate 111 is not particularly limited as long as it is a flexible sheet, and may independently be a sheet having a buffer function or have a substantially buffer function. It may be a non-seat. Moreover, although the 1st base material 111 may each independently be a sheet | seat which has elasticity, the sheet | seat which does not have elasticity is preferable.
Hereinafter, a sheet having a buffer function is referred to as a "buffer sheet", and a sheet having substantially no buffer function is referred to as a "non-buffer sheet". Preferably, a buffer sheet is used as the first substrate 111.
As used herein, "buffering function" refers to the function of cushioning the impact applied to an article.
As a buffer sheet, an impact-absorbing sheet, a foamed resin sheet, a nonwoven fabric sheet, and a laminate including these sheets can be mentioned. Examples of the non-buffering sheet include synthetic resin sheets, paper, synthetic paper, and laminates including these sheets. Alternatively, a laminate of a buffer sheet and a non-buffer sheet may be used as the first substrate 111, and such a sheet has a buffer function.

  Examples of the impact absorbing sheet include sheets of a material having rubber elasticity such as thermoplastic elastomers such as polystyrene and polyurethane, natural rubber such as isoprene rubber, and synthetic rubber such as silicone rubber.

  Examples of the foamed resin sheet include polystyrene resins such as polystyrene; polyolefin resins such as polyethylene and polypropylene; and relatively soft thermoplastic foamed resin sheets made of polyurethane resin and the like. The expansion ratio of the foamed resin sheet is not particularly limited, but is, for example, about 2 to 40 times. Preferably, a foamed polystyrene resin sheet having a foaming ratio of 2 to 10 (more preferably 3 to 7) is used. As the expanded polystyrene resin, in addition to general purpose polystyrene, a copolymer obtained by copolymerizing butadiene, acrylonitrile, methacrylic acid, acrylic acid, acrylic esters and the like with polystyrene is used as a main component, and other resins, additives and the like are blended (Containing 60% by weight or more (preferably 80% by weight or more) of a styrene component) and the like. Moreover, you may use the laminated body by which the non-foamed sheet was laminated | stacked on foamed resin sheets, such as the said expanded polystyrene resin sheet. The non-foamed sheet is provided for the purpose of protection of the foamed resin sheet, improvement of printability and the like. Examples of the non-foamed sheet include those similar to the synthetic resin sheet described later, and preferably a polystyrene resin sheet. Specifically, a polystyrene resin sheet consisting of a single substance or a mixture of polystyrene, a styrene butadiene copolymer, a styrene acrylic copolymer, etc., polyethylene or an ethylene vinyl acetate copolymer, etc. is blended with the single substance or a mixture of polystyrene. And polystyrene resin sheets comprising a styrene component of 60% by weight or more. When the laminate of the foamed resin sheet and the non-foamed sheet is used as the first substrate 111, the non-foamed sheet may be laminated only on one side of the foamed resin sheet, or laminated on both sides. It is also good.

The non-woven fabric sheet is not particularly limited, and for example, fibers such as polyester, polypropylene, polyethylene, rayon paper, nylon or cupra are made into a sheet by a spun bonding method, an adhesion method, a needle punching method or a melt blowing method. Non-woven fabrics can be used. Although the weight per unit area of the non-woven fabric sheet is not particularly limited, it is preferably 5 g / m ² or more, more preferably 10 g / m ² or more, from the viewpoint of exhibiting a sufficient buffer function.

  The thickness of the shock absorbing sheet, such as the shock absorbing sheet, the foamed resin sheet and the non-woven sheet, is not particularly limited, but preferably 50 μm or more independently, from the viewpoint of having sufficient buffer function and mechanical strength. 80 micrometers or more are more preferable, and 100 micrometers or more are further more preferable. Further, the upper limit of the thickness of these sheets is not particularly limited, but from the viewpoint of cost effectiveness, they are each independently, for example, 1 mm or less, preferably 800 μm or less.

  Examples of the synthetic resin sheet include polyester resins such as polyethylene terephthalate and polylactic acid; polyolefin resins such as polypropylene and cyclic olefin resin; polystyrene resins such as polystyrene and styrene-butadiene copolymer; polyvinyl chloride resin and the like The synthetic resin sheet which consists of a 1 type, or 2 or more types of mixture etc. chosen from the thermoplastic resin of these can be used. In particular, it is more preferable to use these biaxially oriented sheets. The synthetic resin sheet is different from the foamed resin sheet in that it is non-foamed.

Examples of the paper include plain paper, coated paper, and Japanese paper. Japanese paper is preferred because it can be expected to have a buffer function. Japanese paper can be made by using natural bast long fibers such as mulberry (Kizou), Mitaka (Mitsuta), and Gumpi (Kanpi) as a raw material, and adding handmade paper to this. In the present invention, in addition to the above-mentioned koji, etc., a broad sense of Japanese paper obtained by mechanically grinding various long fiber raw materials such as hemp, kenaf, rayon, wood pulp and synthetic fibers is also included. The basis weight of the paper is not particularly limited, but is ^{usually, 50g / m 2 ~300g / m} 2.

  Examples of synthetic paper include polyester-based synthetic paper and polypropylene-based synthetic paper. As a commercial product of synthetic paper, for example, trade name "Yupo" of Yupo Corporation, trade name "Krisper" of Toyobo Co., Ltd., etc. can be used.

  The thickness of the non-buffering sheet such as the synthetic resin sheet, paper and synthetic paper is not particularly limited, but is preferably 30 μm or more, more preferably 50 μm or more, and more preferably 80 μm or more from the viewpoint of mechanical strength. More preferable. The upper limit of the thickness of these sheets is not particularly limited, but from the viewpoint of cost effectiveness, they are each independently, for example, 200 μm or less, preferably 120 μm or less.

The first substrate 111 may be, if necessary, any known printing layer such as a design print layer, a mechanical reading symbol display layer such as a bar code, a protective layer, a light shielding layer, a gas barrier layer, a light barrier layer, or a sliding layer. Alternatively, a deposited layer may be provided. The various print layers or vapor deposition layers may be provided independently on the inner surface side of the first substrate 111, or may be provided on the outer surface side of the first substrate 111, or , And may be provided on the inner surface and the outer surface of the first base 111. In addition, the first base material 111 may be provided with a printing layer for printing such as a laser coloring layer, a laser printing layer, a thermal printing layer, an inkjet printer ink receiving layer, or the like, as necessary. A functional film (for example, a laser coloring film, a thermal paper, etc.) may be laminated. These print layers or vapor deposition layers are not shown.
The first substrate 111 may be either transparent (transparent means colorless and transparent or colored and transparent) or opaque. In the case of buffer sheets, they are usually often opaque.

The shape in plan view (the outer shape in plan view) of the first base material 111 is not particularly limited, and as shown in FIG. 1, besides being substantially rectangular, it is not particularly illustrated, but substantially square, substantially circular, substantially elliptical The shape includes a substantially polygonal shape such as a substantially triangular shape or a substantially hexagonal shape. In the present invention, "approximately" in a plan view shape means a shape acceptable in the technical field to which the present invention belongs. For example, the “substantially” having a substantially rectangular shape, a substantially square shape, a substantially triangular shape, and a substantially polygonal shape is a shape in which the corner is chamfered, a shape in which a part of the side is slightly expanded or recessed, or a side is slightly curved Shape etc. are included. Further, the “substantially” having a substantially circular shape and a substantially elliptical shape includes, for example, a shape in which a part of the circumference is slightly expanded or depressed, a shape in which a part of the circumference is slightly straight or hatched, and the like. In addition, "planar view shape" says the shape seen from the direction perpendicular | vertical with respect to the outer surface of a base material.
In the illustrated example, the first base material 111 is formed in a substantially rectangular shape in plan view with the A direction as the longitudinal direction, but may be formed in a substantially rectangular shape in plan view with the B direction as the longitudinal direction.

  The size in plan view of the first base material 111 can be appropriately set according to the size of the article. The first base 111 is formed in a size that can form the first window 113 larger than the planar shape of the article.

A first window 113 is formed in the plane of the first base 111 except for the open end.
The open side end means a side end of the first base 111 which is open at the side edge.
The first substrate 111, which is a sheet independent of the second substrate 121, is completely open at its peripheral edge, and has an open end over the entire periphery thereof. The first substrate 111 having a substantially square shape in plan view as in the illustrated example has an open side end in four directions on a conceptual basis. The open side end is a partial area of the first base 111, which includes the open side edge of the first base 111 and extends in a strip shape in plan view with a desired width.
One open side end is a region extending in a band shape in the A direction including the side edge X on the B direction X side, and the other open side end is on the B direction Y side (Y side in the B direction It is a region that extends in the shape of a band in the A direction, including the side edge Y opposite to the X side. In addition, one open side end is a region extending in a band shape in the B direction including the side edge Z on the A direction Z side, and the other open side end is the A direction W side (the A side W It is a region extending in a band direction in the B direction, including the side edge W opposite to the Z side in the direction.
Each open side end can be conceptually conceived as the remainder of the first base 111 excluding the first window 113. The width of each open side end may be equal to or longer than the length that can form at least one first adhesive portion 112 described later. In specific numerical values, the width of each open end is independently 15 mm to 200 mm.
In the illustrated example, the widths of the two open side ends opposed in the A direction are substantially the same, and the widths of the two open side ends opposed in the B direction are substantially the same.

The first window portion 113 is an opening portion surrounded by an endless annular cutting edge 113 a formed in a plane of the first base 111 in a plan view. The plan view shape of the first window portion 113 (cutting edge 113a) is not particularly limited, and as shown in FIGS. 1 and 5, in addition to the substantially rectangular shape, although not particularly illustrated, the substantially square shape, the substantially circular shape Examples of the shape include a substantially oval shape, a substantially triangular shape, a substantially hexagonal shape, and the like.
The size of the first window 113 in a plan view can be appropriately set according to the size of the article, and usually, the first window 113 is formed to be larger than the plan view shape of the article.

A plurality of first adhesive portions 112 are provided on the inner surface of the first base 111.
For example, the plurality of first adhesive portions 112 are provided on the inner surfaces of all the open side ends of the first base 111. In other words, in the first base material 111 in which the first window portion 113 is formed in the plane, a plurality of partial first adhesive portions 112 are provided over the entire inner surface of the first base material 111. There is.
The first adhesive unit 112 is made of an adhesive. The surface of the first adhesive unit 112 made of an adhesive can adhere to the adherend. Hereinafter, the adhesive which comprises the 1st adhesion part 112 is called "1st adhesive."
Specifically, the first adhesive portion 112 is formed by providing a plurality of first pressure-sensitive adhesives on the inner surface of each open end of the first base 111. The first pressure-sensitive adhesive is strongly adhered to the inner surface of the first base 111, and can not be peeled off from the inner surface.
The surface of the first adhesive unit 112 has adhesiveness. The outer surface of the first substrate 111 is not provided with the first adhesive, and thus the outer surface of the first substrate 111 has no tackiness.

As shown in FIG. 1 and FIG. 5, the plan view shape of the first adhesive section 112 (first adhesive) is a linear and strip extending in any one direction in the plane of the first base 111. A plurality of strip-like first adhesive portions 112 (first adhesive) are formed in parallel in another direction (direction orthogonal to the one direction) with a desired interval.
For example, the plurality of first adhesive portions 112 are each formed to extend in a band shape in the A direction.
The first adhesive portions 112 extending in a strip shape in the A direction are disposed intermittently in the B direction, and a portion having no adhesive is provided between the adjacent first adhesive portions 112. The part which does not have an adhesive does not have adhesiveness, and can not adhere. Hereinafter, the part which does not have adhesiveness may be called "non-adhesive part." The peeling process is performed to the part which does not have the said adhesive among the inner surfaces of the 1st base material 111. As shown in FIG. The said peeling process is given as needed.

Peeling treatment refers to treatment for reducing or eliminating the adhesion of a pressure-sensitive adhesive or an adhesive. It becomes difficult for the adhesive and the adhesive to adhere to the part subjected to the peeling treatment, and the adhesive and the adhesive can be easily peeled from the part. As the peeling treatment, conventionally known treatment can be used, and typically, applying a peeling agent such as silicone to the inner surface of the first base 111 is mentioned. However, the release agent is not shown. The portion subjected to the peeling process is referred to as a "first peeling portion 115". The adhesive does not adhere to the first peeling portion 115 with a sufficient adhesive force, and the adhesive can be easily peeled off manually.
Therefore, on the inner surface of the first base 111, the first adhesive portions 112 extending in a band shape in the A direction and the first peeling portions 115 extending in a band shape in the A direction are alternately arranged in the B direction. In the illustrated example, the first adhesive portions 112 and the first peeling portions 115 alternately arranged in the B direction have the same number, and the first adhesive portions 112 and the first peeling portions in order from the B direction X side to the Y side 115 are alternately arranged.
The strip-like first adhesive portion 112 and the first peeling portion 115 are not limited to being extended in the A direction, and may extend in the B direction, or are inclined with respect to the A direction It may extend in the direction.

The 1st adhesion part 112 and the 1st exfoliation part 115 are provided in the shape of a belt over the whole in the A direction like the example of illustration. That is, the first adhesive portion 112 and the first peeling portion 115 are respectively provided in a band shape from the side edge Z on the A direction Z side of the first base 111 to the side edge W on the W side. However, at the open side end on the A direction Z side and the W side, which is the open side end where the first window portion 113 exists in the middle in the A direction, the first adhesive portion 112 and the first peeling portion 115 are Each of the first base material 111 is provided in a band shape from the side edge Z to the cutting edge 113a and from the side edge W to the cutting edge 113a.
However, at the open side end on the A direction Z side and the W side, the first adhesive portion 112 and the first peeling portion 115 are each independently, for example, a surface slightly smaller than the side edge Z and / or the side edge W It may be provided from an inward position, and may also be provided from a position slightly offset from the cutting edge 113a.

The width of the first adhesive portion 112 (the length of the first adhesive portion 112 in the B direction) and the width of the first peeling portion 115 (the length of the first peeling portion 115 in the B direction) are not particularly limited. It can be set.
The width of the first adhesive portion 112 is preferably 3 mm or more, more preferably 5 mm or more, and still more preferably 7 mm or more, since the first packaging material 11 can be adhered well to the adherend. Further, the first adhesive portion 112 preferably has a width of 15 mm or less, more preferably 10 mm or less, because the first packaging material 11 adhered to the adherend can be easily peeled off from the adherend.
In addition, when the width of the first peeling portion 115 is too small or large, the ratio of the first adhesive portion 112 to the inner surface of the first base 111 is relatively large or small. From this point of view, the width of the first peeling portion 115 is preferably substantially the same as the width of the first adhesive portion 112 or slightly larger than the width of the first adhesive portion 112. Furthermore, as described later, since the first packaging material 11 and the second packaging material 12 are easily made to face each other and integrated, the width of the first peeling portion 115 is the width of the first adhesive portion 112 × 1 to 1 The width of the adhesive portion 112 is preferably 1.5, and more preferably, the width of the first adhesive portion 112 is exceeded and the width of the first adhesive portion 112 is 1.3 or less.

The plurality of first adhesive portions 112 may all have the same width, or some of the first adhesive portions 112 may be larger or smaller than the width of the remaining first adhesive portions 112, or all of the first adhesive portions 112 may be The adhesion parts 112 may have different widths.
The first peeling parts 115 may all have the same width, or some of the first peeling parts 115 may be larger or smaller than the width of the remaining first peeling parts 115, or all of the first peeling parts The widths 115 may be different from one another.
In the illustrated example, all the first adhesive portions 112 are formed to have the same width as one another, and all the first peeling portions 115 are formed to have the same width as one another.

In addition, the first adhesive portion 112 may be disposed including the side edge X on the B direction X side of the first base material 111, but preferably, it is slightly in-plane from the side edge X of the first base material 111 It is preferable to be disposed close to. In this preferred embodiment, the edge including the side edge X of the first substrate 111 is a non-adhesive portion, and the non-adhesive portion extends in the A direction. By arranging in this manner, a non-adhesive portion is formed at the edge of the open side end on the B direction X side.
In addition, the first adhesive portion 112 may be disposed to include the side edge Y on the B direction Y side of the first base material 111, but preferably, the side surface Y of the first base material 111 is slightly in-plane It is preferable to be disposed close to. In this preferred embodiment, the edge including the side edge Y of the first substrate 111 is a non-adhesive portion, and the non-adhesive portion extends in the A direction. By arranging in this manner, a non-adhesive portion is formed at the edge of the open side end on the B direction Y side.

The first adhesive portion 112 can be formed by applying a first adhesive to a desired range of the inner surface of the first base 111.
The first pressure-sensitive adhesive is not particularly limited as long as it has adhesiveness to adhere to an adherend at room temperature.
Here, the pressure-sensitive adhesive is an agent having adhesiveness at room temperature and capable of adhering to an adherend, and refers to one that maintains its adhesiveness even after adhering to the adherend. Preferably, the pressure-sensitive adhesive is an agent that can be adhered to an adherend with an adhesive force that can be peeled off from the adherend and can be re-adhered after peeling. The above-mentioned pressure-sensitive adhesive does not have adhesiveness before it is adhered to an adherend, but it also includes one which exhibits adhesiveness by heating or reacting when it is adhered to an adherend.

The first pressure-sensitive adhesive is, from the viewpoint of the material, a pressure-sensitive adhesive containing an acrylic resin as a main component, a synthetic rubber such as styrene isoprene rubber (SIS) or a pressure-sensitive adhesive containing an elastomer as a main component, ethylene-vinyl acetate copolymer And pressure-sensitive adhesives containing an ethylene-based resin as a main component, and pressure-sensitive adhesives containing a urethane-based resin as a main component.
Examples of the properties of the first pressure-sensitive adhesive include an emulsion type, a solvent-soluble type, and a hot melt type.
In addition, from the viewpoint of tackiness of the first adhesive, the pressure-sensitive adhesive, which exhibits adhesiveness even after being applied to the first substrate 111 and does not heat it, is applied to the first substrate 111. The heat-sensitive type adhesive etc. which exhibit adhesiveness by heating after a work and which it continues are mentioned. Examples of the pressure-sensitive adhesive include pressure-sensitive adhesives containing an acrylic resin, a styrene-based rubber, a styrene-based elastomer, a urethane-based resin or the like as a main component. Examples of the heat sensitive adhesive include a hot melt adhesive and a part coat adhesive.

The first pressure-sensitive adhesive may be a pressure-sensitive adhesive having a buffer function, or may be a pressure-sensitive adhesive having substantially no buffer function. Hereinafter, a pressure-sensitive adhesive having a buffer function is referred to as "buffered pressure-sensitive adhesive", and a pressure-sensitive adhesive having substantially no buffer function is referred to as "non-buffered pressure-sensitive adhesive". Preferably, a buffer adhesive is used as the first adhesive.
Therefore, the first packaging material 11 comprises (A) a first base material 111 made of a buffer sheet and a first adhesive portion 112 made of a buffer adhesive, or (B) a first base material 111 made of a non-buffer sheet. (C) A combination of a first base 111 made of a buffer sheet and a first adhesive part 112 made of a non-buffer adhesive, preferably (A) A) It is comprised by the combination of the 1st base material 111 which consists of a buffer sheet, and the 1st adhesion part 112 which consists of a buffer adhesive.

As said buffer adhesive, a foaming adhesive is mentioned typically. Non-buffering adhesives include non-foaming adhesives.
The foamed pressure-sensitive adhesive is a pressure-sensitive adhesive having cells (cells) in the pressure-sensitive adhesive layer, and is a pressure-sensitive adhesive having elasticity. The cells may be closed cells, open cells, or a mixture of closed cells and open cells.
About the material of a foaming adhesive, property, and adhesiveness expression property except having having air bubbles, it can select suitably from the above. Similarly, the material, properties and tackiness of the non-foamed pressure-sensitive adhesive can be appropriately selected from those described above.

As a foaming pressure-sensitive adhesive, (1) a pressure-sensitive adhesive composition which is applied to a sheet while being foamed by a chemical foaming method or a physical foaming method, (2) a pressure-sensitive adhesive composition containing thermally expandable microcapsules An article is applied to a sheet, which is heated to expand the thermally expandable microcapsule, and the like.
In the foaming pressure-sensitive adhesive of the above (1), the chemical foaming method comprises mixing the pressure-sensitive adhesive composition with an inorganic foaming agent, an organic foaming agent or a mixture thereof, and generating nitrogen gas or carbonic acid generated during the decomposition reaction. It is a method of generating air bubbles in the adhesive using gas or the like. The physical foaming method is a method of mixing air, carbon dioxide gas, nitrogen gas, argon gas, helium gas or the like under heat and pressure with the pressure-sensitive adhesive composition in a fluidized state, and then foaming under atmospheric pressure.
The foamed pressure-sensitive adhesive (2) may be foamed substantially at the same time as coating on the first substrate 111 by heating at the time of coating, or may not be foamed at the time of coating, and thereafter It may be made to heat and foam to timely (for example, just before making the 1st packing material 11 adhere to a covering object etc.). In the foamed pressure-sensitive adhesive (2), when the first adhesive portion 112 and the second adhesive portion 122 overlap, the first adhesive and the second adhesive may react to foam. By using a foamed adhesive which can be foamed at the stage of producing an article package using the packaging material without foaming the foamed adhesive in the state of the packaging material (for example, not foaming at the time of coating as described above) The first packaging material 1P can be stored and transported with the thickness reduced as much as possible.
The content of cells of the foamed pressure-sensitive adhesive can be indicated, for example, by the density. In that it has a good buffering function, the density of the foam adhesive ^is preferably ^{0.2g / cm 3 ~0.8g / cm 3} , in 0.3g / cm ³ ~0.7g / cm 3 It is more preferable that

The thickness of the first pressure-sensitive adhesive (the thickness of the pressure-sensitive adhesive layer) is not particularly limited, and can be set as appropriate. The thickness of the first pressure-sensitive adhesive may be uniform or uneven. In the case where the thickness of the first pressure-sensitive adhesive is uneven, for example, when the thickness of a portion of the first pressure-sensitive adhesive constituting the first pressure-sensitive adhesive portion 112 extending in a band is different from that of other portions; When the thickness of each 1st adhesive which comprises the 1st adhesion part 112 differs, etc. are mentioned. When a buffer pressure-sensitive adhesive such as the foam pressure-sensitive adhesive is used, its thickness is, for example, 100 μm to 2 mm, preferably 200 μm to 1.5 mm. The thickness of the foamed pressure-sensitive adhesive refers to the thickness after foaming (in the state of having bubbles).
In addition, when the said non-buffering adhesive is used, the thickness is 15 micrometers-50 micrometers, for example.

A first stretchable sheet 114 covering the first window 113 is fixed to the first base 111. The plan view shape of the first stretchable sheet 114 is not particularly limited as long as it has the same shape and size as the plan view shape of the first window portion 113 and may be larger than the plan view shape of the first base 111 Alternatively, it may be the same shape and size as the first base 111, or may be smaller than the first base 111. Preferably, the first stretchable sheet 114 is larger than the first window portion 113 and smaller than the planar shape of the first base 111. In the illustrated example, the plan view shape of the first extensible sheet 114 is the same shape and size as the plan view shape of the first base 111.
The peripheral region of the first stretchable sheet 114 is fixed to the first base 111. In the first stretchable sheet 114 which is larger than the first window portion 113, the peripheral region is on the outer surface of the first base 111 while covering the first window portion 113 in the central region of the first stretchable sheet 114. It is secured to the first substrate 111 by being non-peelably rigidly adhered to the outer surface of the first substrate 111, with its peripheral area being adhered with an appropriate adhesive (not shown).

The first stretchable sheet 114 is a sheet excellent in flexibility and extensibility, and is a sheet which is stretched without being broken when a load is applied in the normal direction from one side (inner surface or outer surface) thereof.
As the first stretchable sheet 114, for example, a polyethylene-based sheet, a polyurethane-based sheet, a rubber or an elastomer sheet or the like can be used.
The first stretchable sheet 114 may be either transparent (transparent means colorless transparent or colored transparent) or opaque. The polyethylene-based sheet, polyurethane-based sheet, rubber or elastomer sheet and the like are often colored and transparent (transparent to show milky white).
The thickness of the first stretchable sheet 114 is not particularly limited, and is, for example, 20 μm to 100 μm.

On the inner surface of the second base material 221, strip-like second adhesive portions 222 and second peeling portions 225 extending in the A direction are alternately disposed in the B direction.
The second adhesive portion 222 may be provided along the entire A direction, but when the first packaging material 21 is superimposed, the first stretchable sheet 214 adheres to the second adhesive portion 222. As a result, there is a possibility that the first packaging material 21 and the second packaging material 22 can not be separated. In such a case, the first packaging material is obtained by subjecting the exposed inner surface of the first stretchable sheet 214 (the inner surface of the first stretchable sheet 214 exposed at the first window portion 213) to a peeling treatment. 21 and the second packaging material 22 can be adhered in a releasable state. However, since performing the peeling process on the exposed inner surface of the first extensible sheet 214 is troublesome, in the present embodiment, a region corresponding to the first window portion 213 in the inner surface of the second base material 221 is selected. Except for the second adhesive portion 222 is provided.
Although the second stretchable sheet may be laminated and bonded to the outer surface of the second base material 221, the second stretchable sheet is not stacked in the illustrated example.

The second packaging material 2P also peels off the first packaging material 21 (first base material 211) and the second packaging material 22 (second base material 221) from the open end, and the first packaging material 21 and the second packaging material 22 can be separated.

[Third Embodiment of Packaging Material]
The packaging material of the third embodiment (hereinafter referred to as the third packaging material) is the first embodiment in that the base material piece is left in the opening part surrounded by the cutting edge formed on the first base material. It differs from the form and the second embodiment.
In FIG. 12 to FIG. 14, the third packaging material 3P is in the form of a sheet as a whole, and has an independent first packaging material 31 and a second packaging material 32, and the first packaging material 31 and the second packaging material The members 32 are releasably adhered to one another from at least one open end. The third packaging material 3P has flexibility to be bent or bent.

As shown in FIG.
The first window portion 313 is an opening portion surrounded by a cutting edge 313 a formed in the plane of the first base material 311. In the present embodiment, the base piece 316 is present in the opening portion surrounded by the cutting edge 313a. The base piece 316 is separated from the flat first base member 311 by the cutting edge 313a, and the first base member 311 having the first window portion 313 and the base piece 316 have the cutting edge 313a. Boundaries are separated and independent of each other.

For example, as shown in FIG. 13 and FIG. 14, a release layer 317 containing a release agent such as silicone is laminated on the outer surface of the base piece 316. Furthermore, a resin layer 318 is laminated on the outer surface of the release layer 317. The resin layer 318 can be formed, for example, by applying an overcoat varnish or the like. The resin layer 318 adheres to the release layer 317 with an extremely small adhesive force, and is laminated in a state where it can be easily removed from the release layer 317. When the first stretchable sheet 314 is attached to the outer surface of the first base 311 including the base piece 316 via an adhesive by providing the release layer 317 and the resin layer 318, the base piece 316 The release layer 317 and the resin layer 318 are interposed between the and the adhesive.
The adhesion of the resin layer 318 to the peeling layer 317 is determined by the adhesion between the first adhesive portion 312 provided on the base piece 316 and the second peeling portion 325 provided on the second base 321 corresponding thereto. The adhesive force between the first peeling portion 315 provided on the piece of material 316 and the second adhesive portion 322 provided on the corresponding second base member 321 is set to be smaller. Such a setting takes into account the adhesion between the first adhesive part 312 and the second peeling part 325 and the adhesive strength between the first peeling part 315 and the second adhesive part 322, and the thickness or peeling of the peeling layer 317 The type or amount of the agent, or the thickness of the resin layer 318 or the forming material may be adjusted.

The second window portion is not formed in the plane of the second base material 321 of the present embodiment, and therefore, the second base material 321 is entirely flat. On the entire inner surface of the second base 321, strip-like second adhesive portions 322 and second peeling portions 325 extending in the A direction are alternately disposed in the B direction. Unlike the second embodiment, the second base member 321 of the present embodiment has a strip-like second adhesive portion 322 and a second peeling portion 325 extending in the A direction over the entire inner surface including the region corresponding to the first window portion 313. Are alternately arranged in the B direction.
The second stretchable sheet may be laminated and bonded to the outer surface of the second base material 321, but in the illustrated example, the second stretchable sheet is not stacked.

The third packaging material 3P of the present embodiment is also in the form of a sheet in which the first packaging material 31 and the second base material 321 are stacked and integrated in a peelable state.

As shown in FIG. 15, the third packaging material 3P having the first packaging material 31 and the second packaging material 32 integrated with each other is, for example, the first packaging material 31 (the first packaging material 31 (the first packaging material 31 The first base material 311) and the second packaging material 32 (second base material 321) can be peeled off. In addition, since the peeling layer 317 and the resin layer 318 as described above are interposed between the base material piece 316 and the first extensible sheet 314, when the first packaging material 31 is peeled off, as shown in FIG. As shown, the first layer 31 and the second layer 32 can be separated by delamination between the release layer 317 and the resin layer 318.
In the second packaging material 32 separated by the delamination between the peeling layer 317 and the resin layer 318, the base piece 316 via the first adhesive portion 312 and the second adhesive portion 322 on the inner surface of the second base member 321. Is glued. On the other hand, in the surface of the first base material 311, the first window part 313 surrounded by the cutting edge 313a is opened in the separated first packaging material 31. In the third embodiment, the separated first packaging material 31 is substantially the same as the first packaging material 11 of the first embodiment.

  An adhesive may be separately interposed between the base piece 316 and the second base 321 for the purpose of firmly integrating the base piece 316 and the second packaging material 32 (not shown). . Alternatively, the peeling portion (first peeling portion) is not provided between the first adhesive portions 312 formed on the base piece 316, and / or is formed on the second base member 321 facing the base piece 316. The base piece 316 and the second packaging material 32 can be firmly integrated even by a method in which the peeling portion (second peeling portion) is not provided between the second adhesive portions 322.
