Talk about the decorative effect of transparent protective film
- Nov 12, 2018 -

The film is one of the structural components in the transparent protective film product. Usually, the film is obtained by extrusion molding, injection molding, and blow molding using low-density polyethylene (PE) and polyvinyl chloride (PVC) as raw materials. Since polyethylene is cheaper and more environmentally friendly, 90% of the film is made of polyethylene. The main process is blow molding. There are many types of polyethylene, and the melting point and density are different.


The transparent protective film is a layer of plastic film applied to the surface of the protected object. The main function is to protect the manufactured and processed products from damage during a series of processes such as handling, inventory, transportation, processing and installation. After that, the protective film is torn off, so that the surface of the protected product is as clean as new and has the decorative effect.


At present, there are many types of transparent protective film products on the market, and the processing technology of the products is constantly improving. Different viscous transparent protective films are required for different product surfaces. Protective film products generally have four series of low viscosity, medium viscosity, high viscosity and extra high viscosity.
