The difference between PE/PVC/POF shrink film

1. Different definitions:

PE film is a material with very good toughness, and it is not easy to crush with ordinary plastic crushers. Because the PE film is soft and tough, it is not easy to shred, not to mention the high temperature of the tool at high speed, which will make the LDPE melt and adhere to the blade. PE pelletizing can be directly put into the feed port of the extruder into strips, and the PE film is dragged into the barrel by the shear force of the screw to heat, melt, and extrude to pelletize. The first-grade material recovered by PE can still be blown film, used for non-food and pharmaceutical packaging, and is also widely used in the production of Oxford leather and tarpaulin, with a bright future.

PVC polyvinyl chloride, with additional ingredients to enhance its heat resistance, toughness, ductility, etc. The top layer of this surface film is lacquer, the main component in the middle is polyvinyl chloride, and the bottom layer is back-coated adhesive. It is a kind of synthetic material that is well-loved, popular and widely used in the world today. Among the materials that can produce three-dimensional surface films, PVC is the most suitable material.

POF means heat shrinkable film. POF stands for multi-layer co-extruded polyolefin heat shrinkable 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 out of the machine, and then processed by special processes such as die forming and film bubble inflation.

2. Different uses:

PE heat shrinkable 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 and tear resistance, and is not easy to break and fear. Moisture and high shrinkage rate.

Due to the unique properties of PVC (rain-proof, fire-resistant, anti-static, easy to shape) and low-input and high-output characteristics of PVC, it is widely used in the building materials industry and packaging industry. Therefore, PVC film has high transparency, good gloss and shrinkage. Features of high rate.

POF is a kind of heat shrinkable film, mainly used for packaging products with regular and irregular shapes. Due to its non-toxic and environmental protection, high transparency, high shrinkage, good heat-sealability, high gloss, toughness, tear resistance, It has the characteristics of uniform heat shrinkage and suitable for automatic high-speed packaging. It is a replacement product of traditional PVC heat shrinkable film.

Widely used in automotive supplies, plastic products, stationery, books, electronics, circuit boards, MP3, VCD, handicrafts, photo frames and other wood products, toys, pesticides, daily necessities, food, cosmetics, canned beverages, dairy products, medicine, Products such as cassettes and video tapes.
