PVC heat shortening packaging is a package of some food products. It has good packaging effect and good shrinkage effect. It is widely used by manufacturers and is used for hot packaging of biscuits and other foods.

It also has the shortcoming: there is plastic temperature after packaging, and the adhesion is not good at low temperature. As the safety performance of food packaging is more questioned by everyone, some food companies have replaced him with POF heat shrinkable film.
The advantages of POF heat shrinkable film are: no bad odor, good flexibility at low temperature, good adhesion and high safety. The defect is that the heat shrinkage effect is not PVC, and it is widely used in shortening packaging of biscuits, instant noodles and other foods.
