Which of the three materials, POF/PE/PVC, has the best shrinkage?

The shrinkage films made of POF/PE/PVC are common heat shrinkable films, so which material has a better shrinkage rate? At what temperature do they shrink? Guangyi Xiaobian will introduce it to you!

The heat shrinkable film shrinkage of POF is large, up to 75%, and it has good flexibility, and it can be used to package goods with any shape. Moreover, the shrinkage of the five-layer co-extruded POF heat shrinkable film treated by special technology is controllable, which meets the requirements of different commodity packaging for shrinkage. Good sealing performance, high strength, suitable for manual, semi-automatic and high-speed automatic packaging, shrinkage temperature is: 130-150 degrees;

The heat shrinkable film shrinkage of PE is 10%-30% in the horizontal direction and 30%-50% in the vertical direction. It is widely used in the whole package of wine, cans, mineral water, various beverages, cloth and other products. The product has good flexibility, strong impact resistance and tear resistance, and is not easy to be damaged and moisture-proof. The shrinkage temperature is about 200 degrees.

Heat shrinkable film shrinkage of PVC: 35-45% in horizontal direction and 20-25% in vertical direction. It has unique properties of rain-proof, dust-proof, insulation and easy molding, and the characteristics of low input and high output of PVC. It is widely used in building materials industry and packaging industry, and has the characteristics of high transparency, good gloss and high shrinkage. The shrinkage temperature is 80-100 degrees.
