How to Choose the Right Shrink Film for Your Products

There are many types of shrink film materials available, such as PVC shrink film, PE shrink film, POF shrink film, etc. So how do you choose the right shrink film material for your products? Below are three different applications of shrink film materials shared by us, hoping to help you make the right choice.
PVC Shrink Film is made from PVC and various additives. It features good transparency, low shrinkage rate, and high strength. The shrinkage rate can be freely adjusted according to user needs, with strong operability and low shrinkage temperature. However, it has poor toughness and cold resistance, and its main use is as label film. Due to the harmful gases produced during its processing and application, its application is increasingly affected by environmental requirements.
PE Shrink Film is, in a sense, a type of PE blown film, with the difference lying in its material formula and mold structure being more suitable for film orientation. Usually, its longitudinal shrinkage rate is much greater than its transverse shrinkage rate. It is widely used in the single-direction shrink packaging of alcoholic beverages, cans, mineral water, various beverages, textiles, and other products.
POF Shrink Film has the advantages of high glossiness, good toughness, high tear strength, uniform heat shrinkage, and suitability for automated high-speed packaging. POF is a multi-layer co-extruded polyolefin heat film, with the intermediate layer using LLDPE and the inner and outer layers using polypropylene (PP). It is made by co-extrusion of three or more layers, followed by special double-bubble synchronous biaxial stretching process. It is widely used in industries such as automotive products, plastic products, stationery, books, and appliances. It also has extensive applications in industries such as children's toys, circuit boards, MP3 players, VCDs, handicrafts, photo frames, daily necessities, food, cosmetics, canned beverages, dairy products, pharmaceuticals, tapes, and other products.
