Abstract
The embodiment of the utility model discloses a high-barrier composite film comprising a base, a PET (Polyethylene Terephthalate) layer covered on the base and a PVDC (Polyvinyl Dichloride) layer coated on the PET layer, wherein cold sealing adhesive is coated on the PVDC layer. According to the utility model, the cold sealing adhesive can be coated on the composite film so as to implement cold seal of the package of the film.
Description
Technical field
The present invention relates to a kind of packaging film, relate in particular to a kind of high-barrier composite membrane.
Background technology
Commodity miscellaneous have packing, or with carton or with metal or use plastic plate, a lot of employing films are also arranged, blister-pack is multiplex in food, medicine, pharmaceutical packing also common plastics bubble-cap and aluminium foil is packed, yet the expensive cost of aluminium foil one is high, and two come quality more crisp, easily broken, make that medicine makes moist, oxidation, rotten.
With film, food and medicine are packed have that cost is low, isolation moisture and the air performance good and pack the good characteristics of persistence, yet during with blister-pack, film seal is often needed heat-sealing, food, medicine when adding hot-seal in packing are heated apt to deteriorate, drug effect is lost, this has brought very large drawback, therefore need to adopt cold seal glue to carry out cold seal to packing, but there be the problem poor with the film adhesion in cold seal glue.
Summary of the invention
Embodiment of the present invention technical problem to be solved is, a kind of high-barrier composite membrane is provided, and comprises basic unit, is covered in the pet layer in basic unit and coats PVDC layer on pet layer, is coated with cold seal glue on the PVDC layer.
Further, described PVDC is the location coating.
Further, be printed with ink lay in described basic unit.
Implement the embodiment of the present invention, have following beneficial effect:
Adopt the present invention, can realize cold seal glue is coated on composite membrane, realize the cold seal of blister-pack.
Description of drawings
Fig. 1 is high-barrier composite membrane structural representation of the present invention;
Fig. 2 is the second embodiment of the invention schematic diagram.
The specific embodiment
For making the purpose, technical solutions and advantages of the present invention clearer, the present invention is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1, a kind of high-barrier composite membrane comprises basic unit 1, is covered in the pet layer 2 in basic unit and coats PVDC layer 3 on pet layer, coating cold seal glue 4 on the PVDC layer.
Further, described PVDC is the location coating.
Be the second embodiment of the present invention as shown in Figure 2, the difference of itself and the first embodiment is to be printed with in described basic unit ink lay 5.
Above disclosed is only a kind of preferred embodiment of the present invention, certainly can not limit with this interest field of the present invention, and the equivalent variations of therefore doing according to claim of the present invention still belongs to the scope that the present invention is contained.
