Abstract
The utility model discloses a kind of self-adhesion and shrink Obstruct membrane, the structure of this packaging film is composited by 5 layers or 7 layers of composite, described 5 layers of composite comprise POE rete 1, TIE rete 2, PA rete 3, TIE rete 2 and EVA film layer 4 from outside to inside successively.7 layers of composite are POE rete 1, TIE rete 2, VMDPE rete 5, TGPA rete 6, PA rete 3, TIE rete 2 and EVA film layer 4 from outside to inside.The beneficial effects of the utility model are, structure is simple, practical.
Description
Technical field
The utility model relates to packaging material application, and particularly a kind of self-adhesion shrinks Obstruct membrane.
Background technology
The self-adhesion used at present shrinks Obstruct membrane, be mostly PE film, after existing PE shrink film carries out two-layer packaging, outer PE shrink film and internal layer PE shrink film easily stick together, when causing dismantling outer PE shrink film, easy destruction internal layer PE shrink film, affect the display of inner wrapping commodity, and packaging film does not have the effect of anti-corrosive antibacterial, this just makes the shelf-life of packaged food very short, expired packaged food can only be thrown away, and causes great waste.
Utility model content
The purpose of this utility model is to solve the problem, and devises a kind of self-adhesion and shrinks Obstruct membrane.
Realizing above-mentioned purpose the technical solution of the utility model is, a kind of self-adhesion shrinks Obstruct membrane, the structure of this packaging film is composited by 5 layers or 7 layers of composite, described 5 layers of composite comprise POE rete 1, TIE rete 2, PA rete 3, TIE rete 2 and EVA film layer 4 from outside to inside successively.7 layers of composite are POE rete 1, TIE rete 2, VMDPE rete 5, TGPA rete 6, PA rete 3, TIE rete 2 and EVA film layer 4 from outside to inside.
Can self-adhesion involution under cryogenic between adjacent two layers.
TGPA rete is high-barrier rete.
The self-adhesion utilizing the technical solution of the utility model to make shrinks Obstruct membrane, and beneficial effect is, can not make to stick together between each tunic, is applicable to the display of inner wrapping commodity, has antibacterial effect, extend the shelf-life of food.
Accompanying drawing explanation
Fig. 1 is the structural representation that self-adhesion described in the utility model shrinks Obstruct membrane 5 layers;
Fig. 2 is the structural representation that self-adhesion described in the utility model shrinks Obstruct membrane 7 layers;
In figure, 1, POE rete; 2, TIE rete; 3, PA rete; 4, EVA film layer; 5, VMDPE rete; 6, TGPA rete.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is specifically described, if Fig. 1-2 is the structural representation that self-adhesion described in the utility model shrinks Obstruct membrane, a kind of self-adhesion shrinks Obstruct membrane, the structure of this packaging film is composited by 5 layers or 7 layers of composite, described 5 layers of composite comprise POE rete from outside to inside successively, TIE rete, PA rete, TIE rete and EVA film layer.7 layers of composite are POE rete from outside to inside, TIE rete, VMDPE rete, TGPA rete, PA rete, TIE rete and EVA film layer; Can self-adhesion involution under cryogenic between adjacent two layers; TGPA rete is high-barrier rete.
The feature of the present embodiment is, the structure of this packaging film is composited by 5 layers or 7 layers of composite, and described 5 layers of composite comprise POE rete from outside to inside successively, TIE rete, PA rete, TIE rete and EVA film layer.7 layers of composite are POE rete from outside to inside, TIE rete, VMDPE rete, TGPA rete, PA rete, TIE rete and EVA film layer.POE rete has high resiliency, the feature of high strength, there is excellent mechanical property, rheological property and anti-ultraviolet property, TIE rete improves the toughness of packaging film, strengthen bonding adhesive attraction, PA rete is wear-resisting, tough, OTR oxygen transmission rate is low, EVA film layer has excellent pliability, resistance to impact, elasticity, optical transparence, low temperature flexing, tackness, environmental stress crack resistance, weatherability, chemical proofing, heat sealability etc., VMDPE rete is in plastic film field, can be used as softening modifier, tearing strength modifier, impact modifying agent mixes with EVA can improve intensity, performance, flexibility and low temperature heat sealing performance, TGPA rete distinguishing feature has fabulous barrier and fabulous processability to gas, the transparency in addition, glossiness, mechanical strength, retractility, wearability, cold resistance and surface strength are all very excellent.
Technique scheme only embodies the optimal technical scheme of technical solutions of the utility model; those skilled in the art all embody principle of the present utility model to some variations that wherein some part may be made, and belong within protection domain of the present utility model.
