POF C-3 environmental shrink film

1, the basic concept of product

POF C-3 the full name of the three-tier co-extruded polyolefin shrink film, it is a linear low-density Polyethylene (LLDPE) and copolymer polypropylene plastics extrusion through three extruders, and then die molding, bubble inflation and other special process with. Products are non-toxic environmental protection, transparency, high shrinkage rate, and good sealing properties, surface gloss, toughness, tear strength, heat-shrinkable packaging uniformity and other characteristics suitable for high-speed automatic, it is a traditional PVC heat The best replacement for shrink film, POF C-3 is currently widely used in food, pharmaceuticals, beverages, alcohol, electrical products, electronic products, toys, daily necessities and other products packaging. Especially its excellent shrinkage characteristics, making it shrink packaging of choice.
