The three common categories of polyethylene film are: POF polyethylene film, PE polyethylene film, and PVC polyethylene film! They have different characteristics:
POF has the characteristics of high surface gloss, good toughness, high tear resistance, uniform heat shrinkage and suitable for automatic high-speed packaging. It is a replacement product of traditional PVC hot polyethylene film. POF is the meaning of thermal polyethylene film. POF stands for multi-layer co-extruded polyolefin thermal polyethylene film. It uses linear low-density polyethylene as the middle layer (LLDPE) and co-polypropylene (pp) as the inner and outer layers. It is plasticized and extruded by an extruder, and then processed by special processes such as die forming and film bubble inflation.
PE hot polyethylene film is widely used in the whole assembly packaging of wine, cans, mineral water, various beverages, cloth and other products. The product has good flexibility, impact resistance, tear resistance, and is not easy to break. Not afraid of damp, large shrinkage. PVC film has the characteristics of high transparency, good gloss and high shrinkage.
