Introduction to the knowledge of polymer protective film

There are many industries in the wholesale market of polymer protective film that can be used, but what should we pay attention to in the process of use, let’s take a look now? 　　 During the production process of PE protective film, it should be improved appropriately. The temperature of the barrel is processed and the cooling method is adopted. Can improve the transparency of the film. In fact, to produce a transparent PP film, water quenching must be used. If air cooling is used, the PP blown film produced is fuzzy and translucent due to the poor cooling effect. For this reason, appropriately increasing the processing temperature and using high-efficiency cooling methods in production are effective ways to improve transparency.　　Add a small amount of polyacrylate resin with good compatibility and transparency to PE protective film and PP protective film. Next: The use environment of polymer protective film Previous: The sealing method of heat shrinkable film
