Heat shrinkable film is used for the sales and transportation of various products. Its main function is to stabilize, cover and protect products. The shrink film must have high puncture resistance, good shrinkage and certain shrinkage stress. There are many kinds of heat shrinkable films, which are used in various fields. What are the differences between PE / POF heat shrinkable films?

PE heat shrinkable film

PE polyethylene, which is a transparent thermoplastic. There are three common types of PE, namely LDPE, HDPE, LLDPE. The monomers of the three kinds of polyethylene are the same, but the process conditions used in the synthesis of these polyethylene are different. Therefore, three different polyethylene varieties are generated, and the properties of the three materials are quite different

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. Moreover, the high temperature of the tool at high speed will melt and adhere to the blade. PE granulation can be directly put into the feeding port of the extruder in strips, and the PE film is dragged into the barrel by the shear force of the screw to heat, melt, extrude and granulation. PE recycled primary material can still be blown film, used for non food and drug packaging, and * * used in the production of Oxford leather and waterproof cloth.

PE heat shrinkable film * * is suitable for the whole * * packaging of wine, cans, mineral water, various beverages, cloth and other products. The product has good flexibility, strong impact and tear resistance, not easy to damage, not afraid of moisture and large shrinkage.

POF heat shrinkable film

POF means heat shrinkable film. POF is fully known as multi-layer coextrusion polyolefin heat shrinkable film. It is made by plasticizing and extruding linear low-density polyethylene as the intermediate layer (LLDPE) and co polypropylene (PP) as the inner and outer layers through three extruders, and then processed by special processes such as die forming and film bubble inflation.

POF is a kind of heat shrinkable film, which is mainly used for packaging products with regular and irregular shapes. Due to its non-toxic and environmental protection, high transparency, high shrinkage, good heat sealing performance, high gloss, strength and toughness, tear resistance, uniform heat shrinkage and suitable for automatic high-speed packaging, POF is a replacement product of traditional PVC heat shrinkable film, * * used in automotive products, plastic products and stationery, Books, electronics, circuit boards, MP3, VCD, handicrafts, photo frames and other wood products, toys, pesticides, daily necessities, food, cosmetics, canned drinks, dairy products, medicine, cassettes and videotapes.
