Abstract
The invention discloses a multifunctional packaging bag, and relates to the field of packing materials and film materials. The multifunctional packaging bag comprises a biaxially oriented polypropylene packaging film body. The thin film of the packaging bag is of a five-layer-film structure, the inner layer is a biaxially oriented polypropylene thin film layer, the outer layer is an indium-tin-oxide transparent thermal insulating thin film layer, a linear low-density polyethylene stretch film layer, a polyethylene plastic double-layer heat preservation film layer and an inner biaxially oriented polypropylene thin film layer are respectively connected between the inner layer and the outer layer. The inner layer and the polyethylene plastic double-layer heat preservation film layer are connected through autohension of the middle linear low-density polyethylene stretch film layer, the used inner layer or the used low-density polyethylene stretch film layer can be torn off so that the bag can be used repeatedly, the inner layer and the low-density polyethylene stretch film layer can also be torn off to be used individually, the outer layer can play a role in heat insulation, and the polyethylene plastic double-layer heat preservation film layer can play a role in heat preservation.

Summary of the invention
The object of the present invention is to provide a kind of Multifunctional packing bag, to solve the above-mentioned multinomial defect causing in prior art.
A kind of Multifunctional packing bag, comprise Biaxially oriented polypropylene packaging bag body, it is characterized in that, the film of described packaging bag is five tunic structures, its internal layer is bidirectional stretching polypropylene film layer, skin is indium tin oxide transparent heat insulation diaphragm layer, be connected to internal layer and be respectively linear low density of polyethylene stretch film layers, vinyon double-layer heat insulation rete, interior thin layer to outer middle trilamellar membrane, described internal layer and vinyon double-layer heat insulation rete are interconnective by the autohension of the linear low density of polyethylene stretch film layers in the middle of it.
Preferably, the internal layer of described packaging bag opening part connects the linear low density of polyethylene stretch film of the wide 40mm of a circle.
Preferably, the skin of described packaging bag connects one deck stiffened polycarbonate film.
Preferably, two sides, the front and back centre portion hollow out of described packaging bag, fretwork area is 1/3rd of an area of packaging bag, the outer one deck thermoplastic polyurethane waterproof breathable membrane that connects of openwork part.
Preferably, the skin of described packaging bag connects the super hyaline membrane of one deck fragrance polyvinylchloride.
The invention has the advantages that: the film of packaging bag is five tunic structures, its internal layer is bidirectional stretching polypropylene film layer, skin is indium tin oxide transparent heat insulation diaphragm layer, be connected to internal layer and be respectively linear low density of polyethylene stretch film layers to outer middle trilamellar membrane, vinyon double-layer heat insulation rete, interior bidirectional stretching polypropylene film layer, internal layer and vinyon double-layer heat insulation rete are interconnective by the autohension of the linear low density of polyethylene stretch film layers in the middle of it, when internal layer can tear it down internal layer with having crossed, when low density polyethylene stretch film layer can tear it down it to reach a nonexpondable object of sack with having crossed, also can be by internal layer, low density polyethylene stretch film layer tears it down and uses separately, when article temperature requirement can not be too high, if exposed to the open air in the sun, skin can play heat insulation effect, vinyon double-layer heat insulation rete can play for connection with wrapping of piece the effect of insulation.
The internal layer of packaging bag opening part connects the linear low density of polyethylene stretch film circle of the wide 40mm of a circle, after packaging bag opening, can seal again, do not need to clamp opening with clip, the skin of packaging bag connects one deck stiffened polycarbonate film, can protect connection with wrapping of piece, in order to avoid scratch easily, two sides, the front and back centre portion hollow out of packaging bag, the outer one deck thermoplastic polyurethane waterproof breathable membrane that connects of openwork part, when article needs are ventilated, can play the effect of waterproof and breathable, the skin of packaging bag connects the super hyaline membrane of one deck fragrance polyvinylchloride, can play optimization air quality, make people's spirit and QI cleaning.
