POF is a heat shrinkable film. The full name of POF is a multi-layer co-extruded polyolefin heat shrinkable film. It uses linear low-density polyethylene as the middle layer (LLDPE) and copolymerized polypropylene (pp) as the inner and outer layers. Through five extruders Plasticized extrusion, and then processed by special processes such as die forming and film bubble inflation.
Mainly used for packaging regular and irregular shaped products, due to its non-toxic environmental protection, high transparency, high shrinkage, good heat sealing performance, high gloss, toughness, tear resistance, uniform heat shrinkage and suitable for automatic high-speed Packaging and other characteristics, 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, cassettes and video tapes and other products.
Main Feature:
1. With high transparency and good gloss, it can clearly display the appearance of the product, improve the sense of perception, and reflect the high grade.
2. The shrinkage rate is large, up to 75%, and the flexibility is good. It can be used to package goods of any shape, and the shrinkage force of the three-layer co-extruded film treated by a special process is controllable, which can meet the requirements of different product packaging on the shrinkage force. Require.
3. Good welding performance and high strength, suitable for manual, semi-automatic and high-speed automatic packaging.
4. Good cold resistance, can maintain flexibility at -50 ℃ without embrittlement, suitable for storage and transportation of packaged objects in cold environment.
5. Environmentally friendly and non-toxic, in line with the US FDA and USDA standards, and can be packaged food.
