What are the commonly used processing materials for heat shrinkable film

The heat shrinkable film of the PE heat shrinkable film manufacturer is mainly used in the sales or transportation of various products, and it can stably protect the product. Next, we will introduce the commonly used processing materials of heat shrinkable film.　　The first is polyethylene. The heat-shrinkable film of this type of material has relatively high impact resistance, and the seal is relatively strong, the price is lower, and the shrinkage temperature is higher, but the gloss is not very good. There is also polypropylene. The heat-shrinkable film of this material has good transparency and gloss, and the shrinkage tension is also very strong. The packaging of records we usually see is the packaging of this material.　　 In addition, polyvinyl chloride is also one of the commonly used materials. PE heat-shrinkable film manufacturers introduced that the heat-shrinkable film of this material has a faster heat shrinkability. The products packaged with this material are transparent and beautiful, and the heat-sealed parts are also very clean. The use is still relatively wide.Next ：Nothing Previous： The working principle of protective film corona treatment
