The difference in adsorption function between PE protective film and PET

During the manufacturing process of PE maintenance film, corona treatment is generally carried out, which increases the outer surface area and static electricity of the film. After that, subsequent adhesive coating operations can be carried out, which can effectively bond the film and adhesive.

PE maintenance film is useful on the inner layer of the film. Its primary raw material during manufacturing is EVA, which has a certain adsorption function when used to complete the entire adsorption function of the film. The electrostatic formula components of these two types of electrostatic films are also different, and the quality and price of the resulting products are also different. Low priced electrostatic films will cause the electrostatic components to be carried on the surface of the product, resulting in product defects and waste.

PE maintenance film is a common type of exterior maintenance film in our daily lives, which is widely used in the fields of mobile phones, laptops, TV screens, LCD screens, etc. due to its good adhesion, non residue and other high-quality features.

In the production process of PE maintenance film, appropriately increasing the processing temperature of the machine barrel and using the method of poly cooling can improve the transparency of the film. In fact, to produce transparent PP film, it is necessary to use water quenching method. If air cooling is used, due to poor cooling effect, the produced PP blown film will be vague and semi transparent. Therefore, appropriately increasing the processing temperature and using high-

efficiency cooling methods in production are effective ways to improve transparency. Adding a few transparent polyacrylate resins with good compatibility to PE maintenance film and PP maintenance film.

Before grasping the differences between PET maintenance film and PE maintenance film, it is necessary to understand their respective definitions, characteristics, and main uses.

PET maintenance film, also known as heat-resistant polyester film, has excellent physical and organic chemical functions and standard stability, transparency, and recyclability. It can be widely used in professions such as magnetic recording, photosensitive profiles, electronic devices, electrical equipment insulation layers, industrial films, packaging and decoration design. It can be produced into mobile phone LCD maintenance film, LCD TV maintenance film, mobile phone keyboard, etc.

PE maintenance film is made of common polyethylene (PE) plastic film as the substrate, and is divided into high-density polyethylene maintenance film, medium density polyethylene, and low-density polyethylene according to different relative densities.

PE maintenance film is a relatively simple polymer material organic compound, widely used in today's society as a fiber material. Its major advantage is that the maintained product will not be affected by environmental pollution, erosion, scratching during the entire process of production, transportation, storage, and application. It maintains the original smooth and shiny surface, thereby improving the quality and competitiveness of the product.

The mechanical equipment for PET maintenance film has high-quality functions, and its strong ductility is the best among all thermoplastic plastics. Its tensile strength and impact compressive strength are much higher than general plastic films. PE maintenance film is a packaging film with comprehensive functions.
