At present, heat shrink film is widely used in the packaging field. The commonly used heat shrink films can be divided into POF heat shrink film, PET heat shrink film, PVC heat shrink film, and PE heat shrink film according to their materials. These four types of heat shrink films each have their own advantages and are an indispensable part of the current packaging field.
Below, we will briefly describe the main applications of these four types of heat shrink films.
1. POF heat shrink film
It is the most widely used and promising among the four types of packaging envelopes. Mainly used for packaging products with regular and irregular shapes. Due to its non-toxic and environmentally friendly properties, high glossiness, strong toughness, tear resistance, high transparency, high shrinkage rate, good heat sealing performance, and uniform heat shrinkage characteristics, it is suitable for high-speed automatic packaging.
Widely used in automotive products, plastic products, food, cosmetics, canned beverages, dairy products, pharmaceuticals, stationery, books, electronics, circuit boards, MP3 players, VCDs, handicrafts, photo frames and other wooden products, toys, pesticides, daily necessities, and cassette tapes. This product is suitable for semi-automatic or fully automatic shrink packaging machines and can automatically block packaging.
2. PET heat shrink film
PET heat shrink film is not only used as a shrink label but also on the outer packaging of daily commodities. Because it can protect packaging items from impact, prevent rain, moisture, and rust, and also win users with beautifully printed outer packaging. At the same time, it can effectively showcase the good image of the manufacturer.
More and more packaging manufacturers are using printed shrink film to replace traditional transparent film. Because printing shrink film can improve the appearance grade of products, facilitate product advertising, and create a deep impression of the trademark brand in the minds of consumers.
3. PVC heat shrink film
PVC heat shrink film is widely used in the packaging of various commodities such as alcohol, food, sports goods, disinfectant tableware, electronic appliances, daily necessities, handicrafts, protective products, audiovisual products, medicines, stationery, toys, portals, plastic hardware, glass ceramics, etc., making its appearance more vivid and beautiful, improving the level of product packaging, and providing protection against dust and messy flowers. It is currently an ideal film packaging material.
4. PE heat shrink film
PE heat shrink film is widely used for whole package packaging of alcoholic beverages, cans, mineral water, various beverages, fabrics, and other products. PE heat shrink film has good flexibility, strong impact and tear resistance, is not easily damaged, is not afraid of moisture, has a high shrinkage rate, and has strong load-bearing capacity.
