The adsorption function of PE protective film

- Aug 29, 2020-

In the process of making 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 combined .

The PE protective film will be effectively on the inner layer of the film. When it is made, its main material is EVA, which has a certain adsorption function during use, so as to realize the entire adsorption function of the film. The electrostatic formulas of these two types of electrostatic films are also different, and the quality and price of the products are also different. The electrostatic film with low price and low grade will transfer the electrostatic components on the surface of the product, resulting in product defects and scrap.

PE protective film is a relatively common surface protective film in our daily life. Due to its high-quality characteristics such as good adhesion, conformity and no residue, it is widely used in mobile phones, laptops, TV screens, LCD screens, etc. field.

In the production process of PE protective film, the processing temperature of the barrel should be appropriately increased and the cooling method should be adopted. Can improve the transparency of the film. In fact, to produce transparent PP film, water quenching method must be used. If air cooling is used, the PP blown film produced is fuzzy and translucent due to poor cooling effect. For this reason, appropriately increasing the processing temperature and adopting high-efficiency cooling methods in production are effective ways to improve transparency. Add a small amount of polyacrylate resin with good compatibility and transparency to PE protective.
