Specific embodiment
Below, embodiments of the invention are described.
In the packing method that can absorb impact of the present invention employed have a large amount of independent, the thermoplastic base resin thin slice of little air cushion projection (this thin slice is referred to as can absorb the thin slice of impact hereinafter).This thin slice is by the thermoplastic base resin thin slice being handled, being made it have a large amount of independent, little air cushion projection and make.
For prepare this have a large amount of independent, the thermoplastic base resin thin slice of little air cushion projection, for example, can be attached to a periphery to a thermoplastic resin membrane has on the drum of little in a large number pit, handle with thermovacuum forming mode or press molding mode thereon then, thereby make it have a large amount of small ruts.Then, folded last layer basal film (tread support membrane) on the film that carried out this processing then, is sealing the pit between the stacked double-layer films again.
About the shape of these little air cushion projectioies, can be cylindric, corner post shape, oval column, Any shape such as hemispherical, or the combination of these shapes.About the size of this little air cushion projection, for example, it can have the diameter of 2～20mm, normally the diameter of 3～10mm; It is 2～30mm highly, is preferably 3～20mm.The thickness of the film of this stingy pad projection can be between 5～100 μ m, preferably between 10～50 μ m.Generally, this little air cushion projection is to be distributed in regularly can absorb on the thin slice that impacts, but also can not have the air cushion projection in some zone on thin slice.
This thermoplastic base resin thin slice that will handle to form above-mentioned little pit is not particularly limited.But, consider that their require to form the processing characteristics of small rut, with the salable performance of basal film (tread support membrane), and flexibility and can absorb the performance of impact, preferably use the polyolefin resin of poly-vinyl resin and polypropylene and so on.The most suitable is the low density polyethylene (LDPE) of under high pressure being processed into; Straight-chain low density polyethylene; And have polyethylene and an ethylene copolymer such as α-hydrocarbon system's alkene of 1-butylene, 1-hexene or the 1-octene by (be total to) poly-merization generation when metallocene catalyst is arranged.
Acrylic resin can be the soft polypropylene of low-crystallinity, or has the irregular copolymer of the propylene of other olefines.This polyolefin resin can contain the elastic body of vinyl-vinyl acetate poly-mer and for example ethene-α-olefine elastic body and so on.There is no particular limitation for basal film, can be any any poly-mer that can seal the stingy pad projection of lobed thin slice at least.But common this basal film forms the above-mentioned basic building block that can absorb the thin slice that impacts.Therefore, this basal film will be selected from various types of films according to the application and the condition of service that can absorb the package that impacts.Therefore, this basal film can be any can with the film heat seal single layer polyethylene foil together that has stingy pad projection; By the multilayer film that this poly-vinyl resin and other resin co-extruded are formed; And this polyethylene foil and other pellicular cascades laminate film together.
For example, this film comprises: polyester/polyethylene, polypropylene/ethylene-ethenol copolymer/polyethylene, polycarbonate/polyethylene, aluminium foil/polyethylene, paper/polyethylene and the fabric/polyethylene of the nylon/polyethylene of nylon/polyethylene, polyester/polyethylene, coating vinylidene chloride, coating vinylidene chloride.If needed, also can be by bonding multi-layer resinous of the adhesive resin of the polyolefin resin such as the maleic anhydride of modification.
If needed, the resinous principle in these films can also contain any other resin or elastic body, and various stabilizer, colorant and extending agent.Can absorb in the package that impacts of the present invention, above-mentioned basal film is preferably formed outside face.Therefore, basal film can print various required patterns, just as common packaging bag.Therefore, in the present invention, be according to the condition of service and the size of package, and the article of packaging, select suitable basal film, to consider its intensity, resistance to heat and airbond performance for basal film.But in order to guarantee the vacuum seal of package, the most suitable is the film with airbond performance.
Generally, can absorb that the thin slice that impacts is made up of film with little air cushion projection and basal film.But, if needed, also can be at the additional film of stack one deck on the raised surface that has of film, so this thin slice that impacts that can absorb just has multiple-structure.This thin slice that can absorb impact that has a large amount of little air cushion projectioies is preferably transparent, so can see the content that is packaged in thin slice in-to-in article by this layer thin slice.
Can absorb in the packing method of impacting of the present invention, article packing is well bled afterwards and to interior, to reduce the pressure of interior.Therefore, if in this method, use packaging bag, an opening must be arranged in the packaging bag, so that article are packed into wherein by this opening.After article are packed into by this opening, also must this opening of sealing., can seal, but this needs supplementary equipment therefore or instrument opening for this reason.For saving equipment or instrument, a fastener and an adhesive member can be set at the opening part of packaging bag, come the opening of sealing bags with them.
Below, to describe a kind of handle and have a large amount of separately, the thermoplastic base resin thin slice of little air cushion projection is made has this method for optimizing that has the packaging bag of fastener and adhesive member.The thermoplastic resin membrane is processed into has a large amount of small ruts, then it is layered on the basal film, thereby the small rut between the film that this two superimposed is got up seals up.Having of making in such a way is a large amount of independent, little air cushion projection, can absorb the thin slice that impacts.Meanwhile, perhaps be piled up before or after formation can absorb the thin slice that impacts at double-layer films, a fastener is fixed on the part that does not have stingy pad projection on the thin slice, normally is fixed on the one side (that is, opposite one side) that thin slice has projection with basal film.Thisly on thin slice, form little air cushion projection and in the on-line job of thin slice fastening fastenings, solved a difficult problem of handling bulky thin slice, not so, if these two work steps are finished separately, just can run into this difficult problem inevitably in different operating process.
Below, describe the present invention with reference to the accompanying drawings.Fig. 1 (A) is the schematic cross-sectional view of an embodiment of the expression packing method that can absorb impact of the present invention, wherein, and the outer periphery of above-mentioned packing laminate sheet, heated sealant all except its bleeding point.What this figure was represented is the situation of also not bleeding.Fig. 1 (B) is the state after bleeding in a vacuum, and this moment, article were packaged in this thin slice that can absorb impact airtightly.Fig. 1 C represents an alternative embodiment of the invention, and wherein, the article that pack are installed on the base plate.
Among Fig. 1, mark 1 expression can absorb the package that impacts; Mark 2 expressions have a large amount of independent, the thermoplastic resin membrane of little air cushion projection (can absorb the thin slice that impacts); Little air cushion projection of mark 3 expressions; The common thermoplastic resin membrane of mark 4 expressions; Mark 5 represents to bleed the unit; The article that mark 6 indicates to pack; Mark 7 expression heat sealing parts; The above-mentioned hermetic unit that can absorb the thin slice that impacts of mark 8 expressions; And base plate of mark 9 expressions.Of the present invention can the absorption among the packing method embodiment that impacts shown in Fig. 1 (A), two thermoplastic base resin thin slice (can absorb the thin slice that impacts) 2a and 2b with little in a large number air cushion projection 3 arrange that so promptly, their projection 3 is all towards inside.Can absorb between the thin slice that impacts at these two, clip the article 6 that to pack.Between the part of these two thin slices, be provided with the unit 5 of bleeding, then heated sealant carried out in the neighboring of thin slice,, whereby, make that the space between two thin slices keeps gas tight seal to form heat sealing part 7.Then, by the above-mentioned unit 5 of bleeding it is vacuumized.After bleeding, just a large amount of little air cushion projection that can absorb on the thin slice that impacts sticks on the article airtightly, shown in Fig. 1 (B), this two-layer thin slice partly is sealed, and forms hermetic unit 8.Like this, article just are fixed on the desired location between these two thin slices, can not move.
Fig. 1 (C) represents an alternative embodiment of the invention.In this embodiment, use be thermoplastic base resin thin slice (can absorb the thin slice of impact) 2a and a common thermoplastic resin membrane 4 with a large amount of little air cushion projectioies 3, the article that pack then are contained on the base plate 9.Specifically, base plate 9 is placed on the common thermoplastic resin membrane of this piece 4, and the article that pack then are placed on this piece base plate 9.Like this, the article that pack just can be packed with above-described the same manner.Base plate 9 can be common flat board, but preferably anti-protecting against shock, for example foam sheet of thermoplastic base resin.In order to prevent that packaged article from moving thereon, roughening is preferably carried out on the surface of base plate.If special article are installed thereon, are preferably in and process the pit that the shape with article adapts on the base plate.
In the packing method that can absorb impact of the present invention, the mode of the article of packing there is not special qualification, be the thin slice that can absorb impact as long as be used for the thin slice of connection with wrapping of piece with a large amount of little air cushion projectioies.Therefore, just can and how to pack these factors and suitably determine manner of packing according to the purpose of connection with wrapping of piece.For example, in order to move or, can use by absorbing the packaging bag that the thin slice that impacts is made in order to transport the packing of article individually.Be applicable to the not special qualification of this form that can absorb the packaging bag of impacting of transporting individually.For example, after article packing is in the common packaging bag that can absorb impact, can carry out heat seal to the opening of packaging bag.But such packaging bag needs apparatus for heat sealing and heat seal work step, usually is pretty troublesome thing and use this device at common packing scene.In order to address this problem, suggestion has fastener in the packaging bag that can absorb impact, has not just needed above-mentioned heat seal work step.
Fig. 2 schematically represents the packaging bag that can absorb impact of the present invention, and this packaging bag is provided with a fastener at its opening part, and portion within it, is provided with an adhesive member below above-mentioned fastener, and is equipped with the unit of bleeding.Cross-sectional view after the opening that can absorb the packaging bag of impacting in Fig. 3 presentation graphs 2 amplifies.Fig. 2 (A) is a planar view; And Fig. 2 (B) is a cross-sectional view.Among Fig. 2 and Fig. 3, mark 11 expressions have the packaging bag that can absorb impact of fastener; The opening of mark 12 these packaging bags of expression; Mark 13 expressions can absorb the thin slice that impacts; The little air cushion projection of mark 14 expressions; Mark 15 expression heat sealing parts; Mark 16 expression fasteners; Mark 17 expression adhesive members; The bonding member of mark 18 expression adhering resins; Mark 19 expression air extractors.As shown in Figure 2, fastener 16 is that open end along the opening that can absorb the packaging bag of impacting 11 is provided with.This is a kind of strip fastener, is made up of a raised member 16a and a recessed member 16b.These two members are molten respectively to be welded in each that will link together and can to absorb on the basal film of thin slice of impact.The structure of strip fastener is known.These two members are tightened together mutually or take apart, just can make the closure of openings of packaging bag or reopen.
Adhesive member 17 can be one deck adhering resin layer, but is preferably as shown in Figure 3, is the bonding member made from adhering resin 18.Importantly, this bonding member 18 will be arranged on the inside face of packaging bag, and below fastener 16, on the direction relative with the opening of packaging bag.If bonding member 18 is arranged on the top of fastener 16, near the opening of packaging bag, when fastener tightened up, the bonding member just can only link together partly so.Like this, the bonding member also has not bonded assembly part at last, and this part can not match with the tightening state of fastener well, the result, and packaging bag just can not firmly seal.Another problem that this situation causes is, bonds together in order to make the bonding member, need apply powerful external force in the gamut of member by hand.
The cross-sectional outling of the bonding member of adhering resin is not special to be limited, and it can the side of being, and is semicircle or trapezoidal.Shown in Fig. 3 (A), a preferred embodiment of this bonding member is recessed part and the combination of protruding part.Can absorb the bonding member that forms on the inside face of the thin slice 13a of impact and 13b at each and make packaging bag opening can be sealed, and the airtight conditions of stabilising packaging bag.As long as the bonding mode of bonding member makes packaging bag keep its airtight conditions just enough.Therefore, the function and the conventional fastener of bonding member differ widely, and this bonding member does not require bind strength.The bonding member not necessarily will have recessed (claw shape) structure as the recessed part of fastener.
The function of the bonding member of the adhering resin roughly function with the recessed part of the conventional fasteners that applies one deck bond layer is identical.But their forming mode but differs widely.Specifically, can not replace the fastener (recessed member) that applies with lining cement with the fastener of adhering resin manufacturing.This is because adhering resin is all very soft, hard inadequately usually.Therefore, when two parts need tighten together under pressure, can't push in this recessed part made from the adhering resin of softness and go protruding part.Can be advanced in the recessed part even protrude part, these two parts that tighten together can not guarantee fastening intensity.Perhaps, have the packaging bag of the fastener made from the adhering resin of this softness, just can not obtain the function that its opening is sealed.
There is no particular limitation to make the method for the packaging bag with fastener of the present invention.Usually, the resin of the resin that is used to make fastener and being used to being made adhesive member carries out common resin extruded, to form the two layers of resin that becomes one for fastener and adhesive member.The resin that is used for fastener is essential to a certain degree hard, so that guarantee desired fastening strength, and must carry out heat seal with the film of packaging bag.On the other hand, the adhering resin of the member that is used to bond then can be according to the type of packaging bag film, and thickness and hard degree are carried out suitable selection.
In order to improve the resin that is used for fastener and the adhesive property of the co-extruded resin of the resin of the member that is used to bond, for the resin that is used for fastener, can adopt such as with unsaturated carboxylic acid-modified polyolefin resin, perhaps in resin, add its derivant.The resin that is used for adhesive member is toughness in its surface.The resin bed that adhesive member is used can be gone up at the extendible portion (merging at basal film) of the resin bed that is used for fastener and form, and such pair of resin bed is easy to form with the co-extruded method.
To consider its fastening performance when selection is used for the resin of fastener and merge performance on the inside face of packaging bag film, this resin comprises, for example: low density polyethylene (LDPE), ethene-α-olefine copolymer, ethylene-acrylic acid copolymer, and acrylic resin.The preferred example of resin of member of being used to bond is: ethene-polar ethylene base co-polymer, and the resin that contains these poly-mers.Above-mentioned ethene-polar ethylene base co-polymer comprises vinyl-vinyl acetate copolymer, ethylene-methacrylic acid copolymer, and ethylene-ethyl acrylate copolymer.
The various resins that contain the lining cement composition also can use, for example, ethene-α-olefine copolymer, the copolymer of propylene, butylene and 1-α-olefine with 5 to 10 carbon atoms, the styrene-ethylene-butylene-styrene periodic copolymer, SBS, and SIS.The polar ethylene resin that contains these adhering resins can stably be controlled, and adhering resin and other resins and elastomeric mixture ratio also are controlled.Can from these adhering resins, select a kind of suitable resin according to character, condition of service and the size of packaging bag.
