How to increase the transparency of polymer protective film

Wholesale polymer protective film products play a great role in packaging, but in order to increase its transparency during the production process, the following measures must be followed. The first polymer protective film is a crystalline material. If it is not cooled quickly, it will crystallize quickly, so its transparency and elongation at break will be reduced. So we have to increase its cooling rate, reduce crystallinity, and improve transparency. The second is that the molecular orientation is severely damaged due to blowing and drafting, which leads to a decrease in elongation at break, but the cooling effect of casting production is good, and the transparency can be improved. There is also the addition of an appropriate amount of antifogging agent. On this basis, add a transparent nucleating agent. If you want to increase the transparency of the polymer protective film, you need to produce it in accordance with the requirements mentioned above and improve its quality.
