PE protective film is a kind of protective film with efficient maintenance effect. It has many effects. It can prevent the appearance of the object being maintained from being corroded by harmful gases; it can also prevent the appearance of the object being maintained from being scratched by other things. Appearance; it can also block the appearance of items from the air and prevent them from being oxidized. This kind of protective film has such advantages, so this kind of protective film is sought after by many companies.

Although PE protective film has many advantages that make the company's eyes bright, but with the intensification of environmental protection concepts in various countries around the world, an increasing number of consumers like green environmental protection concepts and do not expect to use too much capital to consume the earth capital. Therefore, the future development direction of this optical protective film is to develop in the direction of being more environmentally friendly and saving capital.

PE is the simplest polymer organic compound and the most widely used polymer material in the world today. PE protective film is based on a special polyethylene (PE) plastic film, which can be divided into high-density polyethylene protective film, medium-density polyethylene and low-density polyethylene according to the difference in density.

So, how does the PE protective film achieve the function of anti-static adsorption? There are two main reasons:

1. It has corona treatment in the process of film making, which increases the surface area of the film and adds static electricity to satisfy the need for gluing later, which is conducive to the connection between glue and film; 2. PE static film without glue is a film The inner layer is made of EVA material, which has the function of adsorption. Multilayer blown film machine casting machine can make this kind of product at one time.

At present, there are about three types of PE protective films: water-based and oil-based pressure-sensitive adhesives with glue, and electrostatic spray gun film without glue. At the same time, electrostatic film is divided into two types: one is the main production of machine mode, the other is the production of co-extrusion blown film machine, and the other is the production of co-extrusion casting machine. Their electrostatic formula ingredients are different, and the quality and quotation of the products are different. The electrostatic film with a low quotation level will cause the electrostatic components to be carried on the surface of the product, resulting in defective and invalid products.
