FIG. 1 is a perspective view showing a package of the present embodiment, and FIG. 1B shows a state viewed from the opposite side of FIG. 1A. The package A of the present embodiment is formed by processing the laminate 10 shown in FIGS.

As shown in FIG. 3A, the laminate 10 is
A transparent outer layer film 1 exposed to the outside of the package, a reinforcing layer 2 disposed inside the outer layer film 1 to reinforce the laminate 10, and a reinforcing layer 2 The package 10 includes an intermediate layer 3 that imparts functionality such as gas barrier properties to the body 10, and a heat seal layer 4 that is exposed on the inner surface side of the package and functions as a heat sealing adhesive layer. By providing the outer layer film 1 with heat sealing properties, the intermediate layer 3
And a specification that does not require the heat seal layer 4 may be used.

An adhesive layer 5 is provided between the outer layer film 1 and the reinforcing layer 2, and an adhesive layer 6 is provided between the reinforcing layer 2 and the intermediate layer 3.
However, an adhesive layer 7 is provided between the intermediate layer 3 and the heat seal layer 4.

As the outer layer film 1, for example, a stretched polypropylene film, a polyethylene terephthalate film, a nylon film, a polycarbonate film, a cellophane film or the like can be used.

The reinforcing layer 2 has a basis weight of 60 to 200 g /
Paper of about m ² , non-woven paper, synthetic paper, or the like can be used. Synthetic paper is obtained by mixing a polymer material with a filler such as an inorganic or organic filler and forming the mixture into a sheet or film. Reinforcement layer 2
Is for reinforcing the laminate 10 so that the package obtained by molding the laminate 10 can maintain its independence. The type, area, thickness, and the like of the reinforcing layer 2 can be appropriately selected as long as the independence of the package is ensured.

As the intermediate layer 3, for example, a stretched polypropylene film, a polyethylene terephthalate film, a nylon film, a polycarbonate film, a cellophane film, an aluminum foil, a polymer thin film, a metal thin film having a metal thin film of aluminum or the like formed thereon, a polymer A transparent thin film having a transparent metal oxide thin film formed on the film surface, an ethylene vinyl alcohol copolymer film, or the like can be used.

As the heat seal layer 4, for example, polypropylene, linear low density polyethylene (LLDPE),
Low density polyethylene styrene (LDPE), ionomer, ethylene-methyl acrylate copolymer (EMA),
Alternatively, a resin such as polyethylene terephthalate (PET) can be used.

As the adhesive layers 5 and 6, for example, polyethylene, ethylene ethyl acrylate (EE
A), ethylene-methyl acrylate copolymer (EM
A), a resin such as an ethylene-acrylic acid copolymer (EAA), an ethylene-methacrylic acid copolymer (EMAA), or an ionomer can be used.

As shown in FIGS. 1 and 2, the reinforcing layer 2 is provided only on a part of the laminate 10. A pattern is printed on the surface of the reinforcing layer 2 that is in contact with the adhesive layer 5, and the pattern can be seen from the outside of the package through the transparent outer film 1 and the adhesive layer 5.

As shown in FIG. 3B, in a region where the reinforcing layer 2 is not provided (region 2b described later), the adhesive layers 5 and 6 are continuous with each other. If all layers other than the reinforcing layer 2 are made of a transparent material, the contents of the package can be seen through this area where the reinforcing layer 2 is not provided.

In the region where the reinforcing layer 2 is disposed, the reinforcing layer 2
As a result, heat is difficult to be transmitted, so that the heat seal layer 4 cannot be sufficiently heated even if heat seal processing is performed. For this reason, in the present embodiment, the laminate 1
A region without the reinforcing layer 2 is provided in the peripheral portion of the laminate 0, and in this region, the laminates 10 are adhered to each other via the heat seal layer 4 to form a package.

Hereinafter, a method for manufacturing the laminate of the present embodiment will be described.

First, as shown in FIG. 4, a picture is printed on a predetermined area 2a of the reinforcing layer 2 and an area 2b on the same surface is printed.
Is coated with a release varnish. For example, using a multi-color printing press, the pattern and the release varnish may be continuously printed in separate printing units. FIG. 4 shows a case where the area 2a on which the picture is printed is rectangular, and a window varnish therein and the surrounding area 2b are coated with a release varnish. Therefore, the surrounding non-reinforced area 2b and the window non-reinforced area 2b are discontinuous.

As the ink layer of the pattern, it is preferable to select a layer having a strong adhesive force to the adhesive layer 5. As the release varnish, for example, a nitrified cotton polyamide resin, a silicone resin, a polyethylene wax, or the like can be used. The release varnish is more effective than the adhesive force to the adhesive layer 5 for the reinforcing layer 2
It is necessary to select a material having a larger adhesive strength to the material.

Next, the outer layer film 1 and the reinforcing layer 2 are bonded together by extrusion lamination (extrusion coating) or laminate coating via the adhesive layer 5. FIG.
As shown in the figure, the reinforcing layer 2 is bonded to the outer layer film 1 via the surface on which the picture is printed and the surface on which the release varnish is applied.

Next, the reinforcing layer 2 is punched out by, for example, a rotary die cutter into a shape surrounding the area 2b to which the release varnish is applied. When punching the reinforcing layer 2, as shown in FIG. 6, the outer layer film 1 is used as a support, and a punching blade 20 is inserted from the direction of the reinforcing layer 2 (downward in FIG. 6) to the middle of the adhesive layer 5. By cutting the adhesive layer 5 halfway with the punching blade 20 in this manner, the reinforcing layer 2 can be reliably punched out without damaging the outer layer film 1.

As described above, the variation in the position where the punching blade 20 reaches can be absorbed by utilizing the thickness of the adhesive layer 5. Therefore, the thickness of the adhesive layer 5 may be set in accordance with the positional accuracy of the punching blade 20 within a permissible range in performance required for the laminate 10.

In order to facilitate the subsequent process of peeling off the non-reinforced area of the reinforcing layer 2, it is desirable to insert a punching blade 20 in the area 2b as shown in FIG. If a cut is made in the region 2b in this manner, a large force is not required at the time of peeling, and the peeling surface can be appropriately controlled.

Next, as shown in FIG. 7, a non-reinforced region of the reinforcing layer 2, that is, a region 2b (dotted portion) to be peeled off,
Apply a thermal adhesive varnish. The application of the thermal adhesive varnish can be performed by printing. Examples of the heat-adhesive varnish include cellulose, polyvinyl acetate, polyacryl, polyolefin, polyester, polyamide, polyurethane, epoxy, amino resin, rubber, diene, and others. Solvent-type, emulsion-type, hot-melt-type, and other adhesives that are the main components of the vehicle can be used.

Next, as shown in FIG. 8, a separate paper 8 is stuck to the surface of the reinforcing layer 2 on which the heat-adhesive varnish has been applied by hot pressing. By this bonding, the reinforcing layer 2 and the separate paper 8 are bonded at the portion where the heat-adhesive varnish is applied, that is, at the non-reinforced region 2b. As the separate paper 8,
Paper, processed paper, synthetic paper, plastic film and the like can be used. In order to reduce costs, the separate paper 8 has a minimum necessary thickness and has a thickness of 50 to 150 mm.
It is preferably in the range of g / m ² .

Next, after the reinforcing layer 2 and the separate paper 8 are bonded together, the separate paper 8 is peeled off from the outer layer film 1 as shown in FIG. 9 to reinforce the cut (cut surface) formed by punching. The layer 2 is cut, the area 2b adhered to the separation paper 8 is separated and removed from the outer layer film 1, and the area 2a remains adhered to the outer layer film 1. Accordingly, by separating the separation paper 8 from the reinforcing layer 2, a composite film in which the region 2 a of the reinforcing layer 2 on which the pattern is printed is bonded to the outer layer film 1 is obtained. At this time, the release varnish in the region 2b is removed from the outer layer film 1 together with the region 2b of the reinforcing layer 2, and the adhesive layer 5 remains on the outer layer film 1.

Finally, the intermediate layer 3 is adhered to the reinforcing layer 2 side of the composite film via the adhesive layer 6. in this case,
For example, extrusion lamination or laminate coating can be used. Next, the heat seal layer 4 is formed on the surface of the intermediate layer 3 with the adhesive layer 7 interposed therebetween, and the laminate 10 shown in FIGS. 2 and 3 can be obtained. When the intermediate layer 3 and the heat seal layer 4 are bonded to each other, extrusion lamination, laminate coating, or the like can be used.

The laminate 10 thus formed is cut, bent, and heat-sealed to produce a self-supporting package. For the production of the package, for example, a conventional bag making machine or the like can be used. The contents may be loaded into the package at the same time as bag making.

In the present embodiment, the self-sufficiency of the package is ensured by providing the reinforcing layer 2 on a part of the laminate 10 forming the package. The range of choices can be expanded. For example, it is possible to use a soft material for another film constituting the laminate 10.

In this embodiment, a pattern is formed on the surface of the reinforcing layer 2 so that the pattern can be seen through the outer layer film 1, so that the reinforcing layer 2 is effective as a part of the design of the package. Can function.

In a member other than the reinforcing layer 2, for example, in a window which is a non-reinforcing region, a pattern can be formed on the outer layer film 1 or the intermediate layer 3. In this case, since the positioning between the pattern of the reinforcing layer 2 and the pattern of the other members may be a problem, one of the patterns or both patterns may be replaced by an endless pattern so that such a problem does not occur. (A pattern in which alignment is not a problem) may be used.

As shown in FIG. 10-a, the reinforcing layer 2 is not provided at the fold portion (corner portion) of the package, or as shown in FIG. It may be a non-reinforced area. Eliminating the reinforcing layer 2 from the fold makes it easier to bend the laminate when manufacturing the package, and has the advantage that a conventional bag making machine can be used as it is. In addition, as shown in FIG. 11, the perforation 21 is formed in a portion of the reinforcing layer 2 that corresponds to the fold of the package, whereby the bending process of the reinforcing layer 2 can be facilitated. Such a perforation 21
Is, for example, using a rotary die cutter, the reinforcing layer 2
Can be formed at the same time as punching. Half cut processing or crease processing may be performed instead of perforation. When the reinforcing layer 2 is bent and disposed at the corner of the package in this manner, the strength of the entire package can be greatly increased, and thus the package can be easily given self-reliance.

The package according to the present invention can be of various types, for example, a side seal type, a two-side seal type, a three-side seal type, a four-side seal type, an envelope-attached seal type, and a gas seal-attached seal (pillow).
Mold, fold seal, flat bottom seal, square bottom seal,
It can be applied to a standing pouch type, gusset type package, and the like.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the package according to the present invention will be described.

First, a pattern was printed on the coated surface of a single-side coated paper (Mitsubishi Paper Corp. art basis weight: 126 g / m ² ) by a multicolor gravure printing method, and a release varnish (inktec K-S1) was applied to portions other than the pattern. Slip OP varnish) was printed at the same time.

Next, isocyanate was applied as an anchor coating agent to the corona-treated surface of a stretched polypropylene (OPP) film having a thickness of 20 μm (Nimura Chemical FOR), and an anchor coating agent was applied to the printing surface (coated surface) of one-side coated paper. Polyethyleneimine was applied. Then, the stretched polypropylene film and the anchor-coated surface of the single-side coated paper were extruded and laminated using a polyethylene resin as an adhesive layer. As a result, the stretched polypropylene film and the one-side coated paper were bonded via the 30 μm polyethylene film.

Next, using a stretched polypropylene film as a support, a punching blade is inserted from the non-printed side (non-coated side) of the single-side coated paper with a rotary die cutter set to a cut depth of 133 μm, and the outer periphery of the printed picture is printed. And the one-side coated paper was cut at the middle window. The value of the cut depth is set so that the cutting edge is located at the center of the polyethylene film as the adhesive layer. That is, the cut depth (133 μm) is equal to the thickness of the polyethylene film (30 μm),
m), that is, a value obtained by adding 15 μm.

The thickness of the polypropylene film (3
0 μm) takes into account the blade height accuracy of the rotary die cutter, the thickness accuracy of single-side coated paper, or the thickness accuracy of the polyethylene film itself, and the blade edge reaches the stretched polypropylene film due to errors and variations. The cutting edge is always kept within the range of the thickness of the polyethylene film so as not to curl or cut the one-side coated paper completely. Although the thickness of the adhesive layer can be set according to the accuracy of the blade height, etc., in this embodiment, the thickness of the adhesive layer needs to be 20 μm or more, and preferably 30 μm or more.

Next, a heat-adhesive varnish (Dainippon Ink Bliss Pack A Kai-2) was applied by gravure printing to a portion to be a non-reinforcement region on the back surface of the single-side coated paper obtained by laminating the single-side coated paper and the polypropylene film. Applied.

Subsequently, high-quality paper (Oji Paper high-quality paper, basis weight: 95 g / m ² ) as a separate paper was passed between the heat rollers on the back side of the one-side coated paper partially coated with the heat-adhesive varnish. Bonded by heat bonding.

Further, the separate paper and the stretched polypropylene film on which one-side coated paper was bonded were wound on separate rolls, whereby the separated paper was peeled off from the single-side coated paper bonded on the stretched polypropylene film. As a result, unnecessary portions other than the design of the single-side coated paper were separated and removed from the stretched polypropylene film together with the release varnish, leaving only the design portion of the single-side coated paper on the stretched polypropylene film.

Subsequently, a vapor-deposited film (Toyo Metallizing 1100: 12 μm thick) in which an aluminum vapor-deposited film was formed on the surface of a polyethylene terephthalate film was used on one side of the composite film composed of a stretched polypropylene film and a picture portion of one-side coated paper. Glued from the side of the coated paper. That is, by extruding and laminating with a polyethylene resin (Mitsui Oil Mirason 11P), the surface of the composite film on one side coated paper side and the vapor deposition surface of the vapor deposition film are bonded to each other using a 15 μm thick polyethylene film as an adhesive layer. did.

Finally, an isocyanate is applied as an anchor coating agent to the non-deposited surface of the vapor-deposited film, and this coated surface and a 20 μm-thick unstretched polypropylene film used as a heat seal layer are applied to a polyethylene resin (Mitsui Oil Mirason 11P). By extruding and laminating them, they were bonded via a 15 μm-thick polyethylene film as an adhesive layer.

The layer structure of the multi-layer film formed by the above steps is as follows. For the pattern printed portion (the portion having the reinforcing layer), stretched polypropylene (20 μm thickness) / polyethylene (30 μm thickness) / anchor coat / peeling varnish / pattern printing / Coated paper (basis weight 126 g / m ² ) / polyethylene (15 μm thickness) / vapor-deposited film (12 μm thickness) / polyethylene (15 μm thickness) / unstretched polypropylene (20
μm thickness).

Also, a portion without a pattern (a portion without a reinforcing layer)
The layer configuration of is drawn polypropylene (20 μm thickness) / polyethylene (30 μm thickness) / polyethylene (15 μm thickness) /
Evaporated film (12 μm thick) / polyethylene (15 μm
Thickness) / Unstretched polypropylene (20 μm thick).

The multi-layer film was wound up and set on a vertical gusset pillow machine (manufactured by Kawashima Seisakusho) to form a package, fill the package with contents, and seal the package. A highly self-supporting gusset bag with visible windows was obtained.

When the above-mentioned multilayer film was set in a bag making machine (manufactured by Seibu Seisakusho), the package was formed, and the package was sealed. A highly reliable gusset bag was obtained.
