There are many types of shrink film materials, such as PVC shrink film, PE shrink film, POF shrink film, etc.So when choosing a shrink film, how to choose the shrink film material suitable for your product?The following are the three different shrink film material applications shared by Xiaobian for you, hoping to help you in your choice.


PVC shrink film is a product made of PVC and a variety of accessories.It has the characteristics of good transparency, low shrinkage and high strength.The shrinkage rate can be freely adjusted according to user needs, the operability is strong, the shrinkage temperature is low, and the stiffness is good, but the toughness and cold resistance of the film are not ideal. Its main purpose is to be used as a label film.Because its processing and application process will produce harmful gases and do not meet the environmental protection requirements, its application is increasingly affected.

PE shrink film is a kind of PE blow molding film in a sense. The difference is that its material formula and die structure are more suitable for the orientation of the film. Under normal circumstances, its longitudinal shrinkage is much larger than the transverse shrinkage. It is widely used in one-way shrink packaging of alcohol, cans, mineral water, various beverages, textiles and other products.

POF shrink film has the advantages of high gloss, good toughness, high tear strength, uniform heat shrinkage, and suitable for automated high-speed packaging.POF is a multi-layer co-extruded polyolefin thermal film. LLDPE is used for the ordinary intermediate layer and polypropylene (PP) is used for the inner and outer layers.It is made by co-extrusion of three or more layers, and then synchronous biaxially stretched by a special double bubble method.It is widely used in automotive products, plastic products, stationery, books, electrical appliances and other industries.It also has a wide range of application value in the industries of children's toys, circuit boards, MP3, VCD, handicrafts, photo frames and other wood products, daily necessities, food, cosmetics, canned beverages, dairy products, medicines, magnetic tapes and other products.
