Performance comparison of heat shrinkable film of various materials

What we usually call heat shrinkable film generally includes: PVC heat shrinkable film, PET heat shrinkable film, PETG heat shrinkable film, OPS heat shrinkable film and other materials. Depending on the material, the chemical and physical properties will be different. 1. PVC film PVC film is a kind of film material commonly used at present. Its price is extremely low, the temperature shrinkage range is large, and the requirements for the heat source are not high. The main processing heat source is hot air, infrared rays or a combination of the two. However, PVC is difficult to recycle and produces toxic gas when burned, which is not conducive to environmental protection. Its use has been banned in Europe and Japan. 2. OPS film As a substitute for PVC film, OPS film is becoming increasingly popular. It has good shrinkage performance and is also conducive to environmental protection. The product is in short supply in the domestic market. High-quality OPS membranes mainly rely on imports, which has become an important factor restricting their development. 3. PETG film PETG copolymer film is not only good for environmental protection, but also can adjust the shrinkage rate in advance. However, due to the excessive shrinkage, it will be limited in use. 4. PET film PET film is an internationally recognized environmentally friendly heat shrinkable film material. Its technical indicators, physical properties, application range and use methods are close to PVC heat shrinkable film, but the price is cheaper than PETG film, and it is currently an advanced single The shrink film has a transverse shrinkage rate of 70% and a longitudinal shrinkage rate of less than 3%. It is non-toxic and non-polluting. It is an ideal material to replace PVC film. Wuhan Plastic Packaging Co., Ltd. was established in 1996.
