Adsorption function and application fields of PE protective film

time:2021/2/26 10:06:28 browse:

In the production process of PE protective film, corona treatment is usually carried out, which will increase the surface area of the film and be charged with static electricity, and then perform subsequent gluing work, so that the film and glue can be well bonded and combined.

The PE protective film will effectively act on the inner layer of the film. In production, its main material is EVA, which has a certain adsorption function in use, so as to achieve the overall adsorption function of the film. The two electrostatic films have different electrostatic formulations, and the product quality and price are also different. Inexpensive electrostatic films transfer electrostatic components to the surface of the product, leading to product deterioration and scrapping.

PE protective film is a common surface protective film in our daily life. Because of its good adhesion, good adhesion and no residual glue, it is widely used in mobile phones, notebook computers, TV screen surfaces, LCD screens and other fields.

In the production process of PE protective film, the processing temperature of the barrel should be appropriately increased, and the method of condensation and cooling should be adopted. It can improve the transparency of the film. In fact, in order to produce a transparent PP film, a water quenching method must be used. If air cooling is used, the blown PP film produced is fuzzy and translucent due to poor cooling effect. Therefore, it is an effective method to improve transparency by appropriately increasing the processing temperature and adopting effective cooling means. Add a small amount of transparent polyacrylate resin with good compatibility to PE protective film and PP protective film.

The raw material of PE protective film is LLDPE, which is soft and has certain tensile properties. The general thickness is 0.05mm-0.15mm, and its viscosity can be changed between 5g-500g according to requirements. The PE material protective film project is divided into electrostatic film, mesh film and so on. Electrostatic film is a non-adhesive protective film, mainly used for surface protection such as electroplating.
