Changshu smooth plastic extrusion factory talk about the purpose of the plastic film

Plastic film is made of PVC, polyethylene, polypropylene, polystyrene and other plastic film, used in packaging and laminating layer. The following works of plastic extrusion factory in changshu to analyze the use of plastic film.

　　1. PVA coated high barrier plastic film USES the

polyvinyl alcohol high barrier composite membrane based on polyethylene plastic base material, the modified PVA water-soluble liquid coating formed in the substrate of high barrier property of plastic film. Because the polyvinyl alcohol high barrier composite membrane has good barrier property and conform to the requirements of environmental protection, so this kind of plastic packaging materials market prospects are very bright, in the food industry has a broad market space.

　　2. The purpose of the two-way stretch polypropylene film BOPP

two-way stretch polypropylene film is to use special line will polypropylene raw material and functional additive mixing, mixing, melting sheet made by stretching after plastic film. The PP plastic original BOPP plastic film not only has the advantages of low density, good corrosion resistant, heat resistant, and plastic film optical performance is good, high mechanical strength, abundant raw material sources.

also can be used in the preparation of electrician membrane, the functional sex of the microporous membrane for high-value-added products, therefore, BOPP plastic film promising prospects.
