How to control the transparency of PE protective film?

PE protective film, full name Polyethylene, is the simplest polymer organic compound and the most widely used polymer material in the world today. PE protective film uses special polyethylene (PE) plastic film as the base material, and is divided into high-density polyethylene protective film, medium-density polyethylene and low-density polyethylene according to the density. The transparency of the PE protective film is critical to the quality of the product. Here, the protective film manufacturer Kai Film will introduce you how to improve the transparency of the PE protective film: 1. The PE protective film is a crystalline material, which is easy to crystallize. If it is not cooled quickly, It is bound to reduce transparency and elongation at break. The blow molding process has poor cooling effect, high crystallinity, and low film transparency. 2. Due to blowing, drafting, and serious molecular orientation, resulting in low elongation at break; while casting production has good cooling effect, low crystallinity, good transparency, low orientation, so high elongation at break and shrinkage Great. 3. Need to add an appropriate amount of anti-fogging agent. 4. On the basis of the above, add a transparent nucleating agent. 5. The choice of raw materials for PE protective film has low haze and high melt index.
