(Multilayer co-extruded polyolefin heat shrinkable film)? OPS shrinkable film? PET shrinkable film? PE, it is a transparent thermoplastic. There are three kinds of PE commonly used, namely LDPE HDPE LLDPE, which have the same monomers, but the process conditions used in the synthesis of these polyethylenes are different, so three kinds of polyethylene are produced, and the properties of the three materials are quite different.PE heat shrinkable film is widely used in liquor, cans and mineral springs. The whole package of water, beverages, cloth and other products has good flexibility, impact resistance and tear resistance. It is not easy to be damaged, not afraid of dampness and shrinkage rate. PE film is a kind of material with good toughness, which is not easy to be crushed by ordinary plastic crusher. Because the PE film is soft and tough, it is not easy to cut, let alone the high temperature of the cutting tool at high speed, which will make LDPE melt and adhere to the cutting edge. The pelletizing of PE can be directly put into the feeding port of the extruder, and the PE film is pulled into the barrel of the extruder by the shear force of the screw to heat and melt out for pelletizing. The primary material recovered from PE can still be blown, used in non-food and pharmaceutical packaging, and widely used in the production of Oxford leather and waterproof cloth.
