During the manufacturing process of PE maintenance film, corona treatment is usually carried out, which will increase the outer surface area of the film and carry static electricity. Subsequently, subsequent coating operations can be carried out, which can effectively combine the film and adhesive.
PE maintenance film will be useful on the inner layer of the film. When manufacturing, the primary raw material is EVA, which has 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 products are also different. Low priced electrostatic films will cause the electrostatic components to be carried on the surface of the product, forming defects and invalidity.
PE maintenance film is a common type of surface maintenance film in our daily life, which is widely used in mobile phones, laptops, TV screen appearances, LCD screens, and other fields due to its high-quality features such as good stickability, stickiness, and no residue.
During the production process of PE maintenance film, appropriately increasing the processing temperature of the machine barrel and selecting the method of condensation 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, the produced PP expansion film is ambiguous and semi transparent due to poor cooling effect. Therefore, Properly increasing the processing temperature and selecting efficient cooling methods during production are useful ways to improve transparency. Adding a small amount of transparent polyacrylate resin with good compatibility to PE and PP maintenance films.
Before grasping the differences between PET maintenance film and PE maintenance film, it is important to understand their respective definitions, characteristics, and main uses.
PET maintenance film, also known as heat-resistant polyester film, has excellent physical functions, organic chemical functions, and standard stability, transparency, and recyclability. It can be widely used in magnetic recording, photosensitive profiles, electronic devices, electrical equipment insulation layers, industrial films, packaging and decoration design, and can be produced into mobile phone LCD maintenance films, LCD TV maintenance films, mobile phone keyboards, and other professions.
PE maintenance film is based on common polyethylene (PE) plastic film, which 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. Fiber materials are widely used in today's society, and its major advantage is that the maintained product will not be affected by environmental pollution, erosion, scratches 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 of 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 versatile packaging film.
