Description
Technical field
The present invention relates to packaging bag field, be specifically related to a kind of Multifunctional packing bag.
Background technology
Along with the raising of people's living standard, people are more and more higher to the requirement of packaging material, membrane material, in
The patent of invention of state's Application No. 201210298310.7 discloses a kind of packing film, and thin film has well
Thermostability and draftability, be possible to prevent the food spoilage that food occurs in the process of circulation, but its function singleness,
Do not possesses the heat insulation or effect of insulation.
Summary of the invention
It is an object of the invention to provide a kind of Multifunctional packing bag, above-mentioned many with solve prior art causes
Item defect.
A kind of Multifunctional packing bag, including Biaxially oriented polypropylene packaging bag body, it is characterised in that described bag
The thin film of pack is five film structure, and its internal layer is bidirectional stretching polypropylene film layer, and outer layer is indium tin oxide
Transparent heat insulation diaphragm layer, is connected to internal layer and is respectively linear low density of polyethylene stretched film to the middle trilamellar membrane of outer layer
Layer, vinyon double-layer heat insulation film layer, interior thin layer, described internal layer and vinyon double-layer heat insulation film layer
Autohension by the linear low density of polyethylene stretch film layers in the middle of it is interconnective.
Preferably, the linear low density of polyethylene of the internal layer connection one wide 40mm of circle of described packaging bag opening part draws
Stretch film.
Preferably, the outer layer of described packaging bag connects one layer of stiffened polycarbonate film.
Preferably, mid portion hollow out in two sides before and after described packaging bag, fretwork area is one area of packaging bag
1/3rd, openwork part outer layer connect one layer of thermoplastic polyurethane waterproof breathable membrane.
Preferably, the outer layer of described packaging bag connects one layer of fragrance polrvinyl chloride and surpasses hyaline membrane.
It is an advantage of the current invention that: the thin film of packaging bag is five film structure, its internal layer is Biaxially oriented polypropylene
Thin layer, outer layer is indium tin oxide transparent heat insulation diaphragm layer, is connected to internal layer to the middle trilamellar membrane of outer layer respectively
Thin for linear low density of polyethylene stretch film layers, vinyon double-layer heat insulation film layer, interior Biaxially oriented polypropylene
Film layer, internal layer and vinyon double-layer heat insulation film layer are by the linear low density of polyethylene stretch film layers in the middle of it
Autohension is interconnective, when internal layer is with having crossed and internal layer can have been torn it down, when low density polyethylene stretch film layer
A nonexpondable purpose of sack is reached, it is also possible to internal layer, low-density are gathered with having crossed it to be torn it down
Ethylene stretch film layers tears it down and is used alone, when article temperature require can not the highest time, if exposing to the open air in the sun,
Outer layer can play heat insulation effect, and vinyon double-layer heat insulation film layer can be that packing material product play insulation
Effect.
The internal layer of packaging bag opening part connects the linear low density of polyethylene stretched film circle of a wide 40mm of circle, works as bag
Can seal after pack opening, it is not necessary to clamp opening with clip, the outer layer of packaging bag connects one layer and adds again
Hard polycarbonate film, can be with protective packaging article, in order to avoid scratching easily, and two sides pars intermedia before and after packaging bag
Dividing hollow out, openwork part outer layer connects one layer of thermoplastic polyurethane waterproof breathable membrane, when article need to ventilate
Time ventilative, can play the effect of waterproof and breathable, it is super transparent that the outer layer of packaging bag connects one layer of fragrance polrvinyl chloride
Film, can play optimization air quality, makes people's spirit and QI cleaning.

Detailed description of the invention
For the technological means making the present invention realize, creation characteristic, reach purpose and be easy to understand with effect, under
Face combines detailed description of the invention, and the present invention is expanded on further.
Embodiment 1:
As it is shown in figure 1, a kind of Multifunctional packing bag, including Biaxially oriented polypropylene packaging bag body, packaging bag
Thin film be five film structure, its internal layer is bidirectional stretching polypropylene film layer, and outer layer is that indium tin oxide is transparent
Thermal insulation film layer, be connected to internal layer to trilamellar membrane in the middle of outer layer be respectively linear low density of polyethylene stretch film layers,
Vinyon double-layer heat insulation film layer, interior bidirectional stretching polypropylene film layer, internal layer is protected with vinyon bilayer
Temperature film layer is interconnective, when internal layer was used by the autohension of the linear low density of polyethylene stretch film layers in the middle of it
Internal layer can be torn it down, when low density polyethylene stretch film layer reaches one with having crossed it can be torn it down
The nonexpondable purpose of sack, it is also possible to internal layer, low density polyethylene stretch film layer are torn it down and be used alone,
When article temperature require can not the highest time, if exposing to the open air in the sun, outer layer can play heat insulation effect, poly-
Vinyl plastics double-layer heat insulation film layer can be the effect that packing material product play insulation.
