Briefly describe the main features and application prospects of POF shrink film

The POF shrink film is called a multi-layer co-extruded polyolefin heat shrinkable film. It uses linear low-density polyethylene as the intermediate layer (LLDPE) and co-polypropylene (PP) as the inner and outer layers. It is plasticized by three extruders. Extrusion, and then processed by special processes such as die forming and bubble inflation. POF heat shrinkable film is mainly used for packaging regular and irregular shape 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, etc. It is a replacement product of traditional PVC heat shrinkable film. It is widely used in automotive products, plastic products, stationery, electronics, circuit boards, MP3, VCD, photo frames and other wood products, toys, daily necessities, food, cosmetics. , dairy products, medicine and video tapes and other products. Let us look at the main features and application prospects of POF shrink film:
The main features of POF shrink film:
1. High transparency and good gloss, which can clearly display the appearance of the product, enhance the sense of consciousness, and reflect the high-grade.
2, the shrinkage rate is large, up to 75%, good flexibility, can be packaged for any shape of the product, and the shrinkage force of the three-layer co-extruded film treated by special process can be controlled to meet the contraction force of different commodity packaging. Claim.
3, good sealing performance, high strength, suitable for manual, semi-automatic and high-speed automatic packaging.
4, good cold resistance, can maintain flexibility at -50 ?° C without brittle fracture, suitable for storage and transportation of the packaged material in a cold environment.
5, environmentally friendly, non-toxic, in line with US FDA and USDA standards, packageable food
6, the role of moisture and dust
Application prospects of POF shrink film
POF heat shrinkable packaging film has a wide range of uses, a broad market, and has the advantages of environmental protection and non-toxicity. Therefore, it has been widely recognized by developed countries in the world, and has basically replaced PVC heat shrinkable packaging film as a mainstream product in heat shrinkable packaging materials. Such as:
1) Cultural and educational supplies - books, photo albums, pens, etc.
2) Crafts - plaster statues, vases, stone carving crafts, etc.;
3) Electrical appliances - dry batteries, batteries, meters, switches, electronic components, etc.;
4) Hardware - such as mechanical parts, small machinery, tools, etc.;
5) Communication equipment - such as telephones, fax machines, etc.;
6) Other products such as medicine, food, tobacco and alcohol, paper, glass products, etc.
7) In addition to being used directly for packaging, the POF heat shrinkable film can also be used for printing after corona treatment to meet the high-demand packaging of the product.
