How to increase the transparency of PE protective film? Jun 27, 2018

How to increase the transparency of PE protective film?

1. PE protective film is a crystalline material, easy to crystallize, if not fast cooling, it will inevitably reduce the transparency and elongation at break. The blow molding process has poor cooling effect, high crystallinity, and low transparency of the film.

2. Due to blowing and drafting, the molecular orientation is severe, resulting in low elongation at break, while the cooling effect of casting production is good, the crystallinity is low, the transparency is good, and the degree of orientation is low, so the elongation at break is high, and the shrinkage is high. it is good.

3. Need to add an appropriate amount of anti-fogging agent.

4. Based on the above, adding a transparent nucleating agent

5. Select low-haze haze and high melting finger selection for PE protective film raw materials.

Hualibao Co., Ltd specializing in the production of PE transparent protective film, the production of transparent PE protective film can be customized according to customer demand for viscosity, thickness, printing patterns and other products,please feel free to contact us for more information.
