Nowadays, the protective film is indispensable in all walks of life. On the one hand, the protective film can prevent the surface of the product from being scratched, on the other hand, it can effectively prevent the dust from falling in and keep the surface clean. In short, the marble transparent protective film plays an important role in the application, it can be said that like the patron saint, it can provide good surface protection for the marble.


From the application point of view, the transparency of the marble transparent protective film is very important. So in production you know how to ensure the transparency of the protective film? The protective film generally used is a PE protective film. The protective film is a crystalline material and easily crystallizes. If it is not cooled rapidly, it tends to reduce transparency and elongation at break. The blow molding process has poor cooling effect, high crystallinity, and low film transparency.


At the same time, a good production process should be selected in the production, and an appropriate amount of anti-fogging agent should be added. On the basis of the above, a transparent nucleating agent is added. Moreover, the raw material of the marble transparent protective film is recommended to be low in haze and high in melting.
