Abstract
The utility model is related to the modification membrane structures of the flexible package composite material of emulsifiable paste class chemicals.It is pasted together by compound adhesive and biaxial tension pet film layer hot pressing including the first Biaxially oriented polypropylene heat-sealing non-thermal cover of film layer, the polyvinylidene chloride film layer is pasted to form sandwich diaphragm by compound adhesive and the biaxial tension pet film layer hot pressing, and the polyvinylidene chloride film face hot pressing stickup of the second Biaxially oriented polypropylene heat-sealing non-thermal cover gluing of film layer and the sandwich diaphragm is compound；Form Biaxially oriented polypropylene heat-sealing film/biaxial tension pet film/polyvinylidene chloride film/four layers of Biaxially oriented polypropylene heat-sealing film structure of composite membrane.After above structure carries out adaptive improvement to high-barrier PVDC films, existing aluminum foil material is substituted, realizes the visuality of product packaging, enhancing Product Safety can also reduce material cost, save metal material simultaneously.
Description
Technical field
The utility model product structure is related to the flexible packing material of the emulsifiable pastes class chemicals such as silicone series glue and lubricating grease, especially
It is the modification membrane structure of above-mentioned flexible package composite material.
Background technology
Silicone adhesive is a kind of similar ointment, once will to be solidified into a kind of tough and tensile rubber solid for the moisture in ingress of air
The material of body.The flexible packing material of existing such product is using the structure with aluminium foil as barrier layer, but aluminium foil is impermeable
Bright property makes product that can not show the coloury performance of its kind, and other transparent materials but because not having very high resistance
Oxygen water preventing ability can not also use.And gas leakage is easily broken off but also the quality of packaged product declines even mistake at aluminium foil wrinkle
Effect, even the safety of packaged product generates hidden danger.
Utility model content
The utility model is directed to above-mentioned existing issue, uses and does barrier material four layers of composite membrane of formation with PVDC films, can
With in the visuality for ensureing that shelf life of products realizes product packaging simultaneously.It is provided simultaneously with the performance for being protected from light and obstructing, and is substantially dropped
Low material cost.
The technical solution of the utility model is a kind of high-barrier transparent composite film structure, including polyvinylidene chloride film
Layer, it is characterised in that further include Biaxially oriented polypropylene heat-sealing film layer and biaxial tension pet film
Layer；The first Biaxially oriented polypropylene heat-sealing non-thermal cover of film layer passes through compound adhesive and biaxial tension poly terephthalic acid second two
Alcohol ester film layer hot pressing is pasted together, and the polyvinylidene chloride film layer is poly- to benzene by compound adhesive and the biaxial tension
Naphthalate film layer hot pressing pastes to form sandwich diaphragm, and the second Biaxially oriented polypropylene heat-sealing film layer is non-thermal
The polyvinylidene chloride film face hot pressing of cover gluing and the sandwich diaphragm is pasted compound；Form Biaxially oriented polypropylene heat
Sealer/biaxial tension pet film/polyvinylidene chloride film/Biaxially oriented polypropylene heat-sealing film four
Layer structure of composite membrane.
Above-mentioned high-barrier transparent composite film structure, the polyvinylidene chloride film are by the poly- inclined of sided corona treatment
Dichloroethylene film.
Existing aluminum foil material is substituted after carrying out adaptive improvement to high-barrier PVDC films using above-mentioned technical proposal, it is real
The visuality of product packaging is showed, enhancing Product Safety can also reduce material cost, save metal material, meet state simultaneously
The direction of family's policy.
Description of the drawings
Fig. 1 show the utility model high-barrier transparent composite film structure sectional view.
Specific implementation mode
Technical solutions of the utility model are described further with reference to embodiment and attached drawing.
As shown in Figure 1, being one embodiment of the utility model high-barrier transparent composite film structure.Including polyvinylidene chloride
Film 1 further includes the first Biaxially oriented polypropylene heat-sealing film 21 and the second Biaxially oriented polypropylene heat-sealing film 22 and two-way drawing
Stretch pet film 3.To the first Biaxially oriented polypropylene heat-sealing film 21 first on dry compound machine
Compound adhesive 4 is applied on non-heat cover, is pasted onto one with 3 hot pressing of biaxial tension pet film after drying
Rise, then to its biaxial tension pet film face coat after compound adhesive 4 is dried with by sided corona treatment
1 hot pressing of polyvinylidene chloride film forms sandwich diaphragm, and 22 non-heat cover of the second Biaxially oriented polypropylene heat-sealing film applies
The 1 face hot pressing of polyvinylidene chloride film of glue and the sandwich diaphragm is pasted compound；Formation Biaxially oriented polypropylene heat-sealing film/
Biaxial tension pet film/polyvinylidene chloride film/four layers of Biaxially oriented polypropylene heat-sealing film is multiple
Close membrane structure.Existing aluminum foil material is substituted after carrying out adaptive improvement to high-barrier PVDC films using above-mentioned technical proposal,
The visuality of product packaging is realized, enhancing Product Safety can also reduce material cost, save metal material, meet simultaneously
The direction of national policy.
The preferred embodiment that these are only the utility model, is not intended to limit the utility model, for this field
Technical staff for, various modifications and changes may be made to the present invention.Within the spirit and principle of the utility model,
Any modification, equivalent replacement, improvement and so on should be included within the right of the utility model.
