Our mobile phones and computers will be pasted with PE protective film, which is a transparent and sticky thin film. Xincai is mainly engaged in the production of PE protective film. The production process of PE protective film is: glue making, coating, drying, rewinding, slitting, packaging, etc. now, the transparency requirements of products for PE protective film are higher and higher, and complex production process It has an impact on transparency. First of all, the choice of raw materials is very important. How to improve the transparency of PE protective film is introduced as follows:

1. PE is a crystalline material, which is easy to crystallize. If it is not cooled quickly, transparency and elongation at break will be reduced. The cooling effect of blow molding is poor, the crystallinity is high, and the film transparency is low.

2. The manufacturing of PE protective film is characterized by blow up, draft and serious molecular orientation, 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 orientation is low, so the elongation at break is high and the retraction is good.

3. Add appropriate antifogging agent.

4. On the basis of the above, add transparent nucleating agent

5. Add a small amount of transparent polyacrylate resin with good compatibility.

6. In order to achieve higher transparency of PE protective film, 0.5-1% homogeneous oil can be added during the production. Homogeneous oil is non-toxic and can be processed into a uniform and transparent colored material together with pigment powder.

7. The addition of nucleating agent can also make the number of crystal nuclei available for crystallization of PE protective film melt at the melting point increase greatly, and the crystallization speed is accelerated, while the crystal particles are refined slightly, so that the crystal does not affect the transparency of the film, so as to improve the crystallinity of PE protective film, improve the strength of the film, and improve the transparency.

Therefore, we need to know that PE protective film can not be realized by using a single aspect, and we need to clearly understand its production process, because in order to improve the transparency of PE protective film, we have to check from the raw materials, production process, and the upper layer of process technology. PE protective film with good transparency will be more and more trusted by customers.
