POF shrink film application range

The heat shrinkable film is designed with the principle of high orientation molecular chain stretching and orientation, and formed by the method of rapid cooling and shaping. Generally speaking, heat shrinkable film is POF, or Polyolefin Shrink Film can pack regular and irregular shaped products. The heat shrinkable film is designed with the principle of high orientation molecular chain stretching and orientation, and formed by the method of rapid cooling and shaping. The physical principle is: when the ionomer is in a highly elastic state, its orientation is stretched, and then the polymer is quenched to below the glass transition temperature, the molecular orientation is frozen, and when the article is heated during packaging , Due to stress relaxation caused by molecular motion, the molecules return to their original state and contraction occurs. Generally speaking, heat shrinkable film is POF, or Polyolefin Shrink Film can pack regular and irregular shaped products. Such as: automotive supplies, plastic products, stationery, books, electronics, circuit boards, MP3, VCD, handicrafts, picture frames and other wood products, toys, pesticides, daily necessities, food, cosmetics, canned drinks, dairy products, medicine, cassettes And video tapes and other products. The application potential in the following areas is quite huge. 1) Hardware-such as mechanical parts, small machinery, tools, etc.; 2) Other products such as medicine, food, tobacco and alcohol, ceramics, paper, glass products, etc. 3) Cultural and educational supplies-books, photo albums, pens and inkstones, etc. 4) Handicrafts-plaster statues, vases, stone carvings, etc.; 5) Communication equipment-such as telephones, fax machines, etc.; 6) Electrical appliances-dry batteries, accumulators, meters, switches, electronic components, etc.; except for direct packaging, POF The heat shrinkable film can also be used for printing after corona treatment, so as to meet the demanding packaging of commodities. In addition, new packaging areas and scopes continue to expand along with market development and consumer practices.
