Block bottom bags commonly used food grade original film
1, two-way stretching polypropylene BOPP: with good printing performance, high transparency, tensile, cold resistant, heat resistant, and 40 degrees – 120 degrees;
2, two-way stretch polypropylene extinction film: the luminosity is small, translucent shape, film of extinction effect;With the support of bags has more texture and class;
3, cast polypropylene CPP: good gloss, good transparency, good heat sealing, its application is very extensive.But not hardy, CPP will be brittle under low temperature environment.The CPP stretch high temperature membrane is suitable for cooking packaging;
4, polyethylene PE: transparency, good gloss, heat sealing resistance, hardy.Also can according to need to be processed into various functional thin film, there are many kinds function.
5, Block bottom bags PET polyester film, has good printing adaptability and resistance to tension, 60-150 degrees heat resistance, good air tightness, and suitable for cooking, no heat sealing;
6, nylon PA or NY: colorless, transparent and softness are higher than BOPP, cold resistant, heat resistant, oil resistant, but cooking.Easy to moisture absorption, no heat sealing;
7, aluminum foil, moistureproof, airtight, shading, abrasion resistance, incense, avirulent insipidity, etc.Aluminum foil with plastic and paper composite, the strength of the block of aluminum foil and paper, plastic heat sealing, necessary to further improved as packing material for steam, air, bacteria and ultraviolet shielding performance.With the aluminum foil packing material, at least can guarantee food more than one year is not bad.
