The adsorption function of PE protective film is different from that of PET

In the process of manufacturing PE maintenance film, corona treatment is generally carried out, which will make the film increase its surface volume and bring static electricity, and then carry out subsequent gluing operations, which can combine the film and glue.

PE maintenance film will be useful on the inner layer of the film, in the manufacturing of its primary raw material is EVA in the use of a certain adsorption function, so as to complete the entire adsorption function of the film, the two kinds of electrostatic formula components are different, the quality and price of the product are different, the price of low level electrostatic film will make the electrostatic components transported on the surface of the product, The formation of bad products and obsolescence.

PE maintenance film is a more common appearance maintenance film in our daily life, because of its good Posting, submission and no residual glue and other high-quality characteristics, is widely used in mobile phones, laptop computers, TV screen appearance, lcd screen and other fields.

PE maintenance film production process, properly improve the cylinder processing temperature and choose the method of condensation, can improve the transparency of the film, in fact, to produce transparent PP film, it is necessary to use water quenching method, such as the use of air cooling, because the cooling effect is not good, the produced PP blowing film is vague, translucent, to this end, The proper improvement of processing temperature and the selection of efficient cooling methods in production are useful ways to improve transparency, and a few polyacrylate resins with good compatibility are added to PE maintenance film and PP maintenance film.

Before grasping the difference between PET maintenance film and PE maintenance film, each should understand their respective definitions, characteristics and main uses.

PET maintenance film nickname film heat-resistant polyester film, it has excellent physical functions, organic chemical functions and standard stability, transparency, recovery and utilization, can be widely used in magnetic recording, photosensitive profiles, electronic devices, electrical equipment insulation layer, industrial film, packaging decoration design and other professions, can be produced into mobile phone LCD maintenance film, LCD TV maintenance film, Mobile phone keyboard, etc.

PE maintenance film is a common polyethylene (PE) plastic film as the base material, according to the relative density is divided into high density polyethylene maintenance film, medium density polyethylene and low density polyethylene.

PE maintenance film, is a relatively simple structure of polymer material organic matter, the use of more widespread fiber data in today's society, its biggest advantage is that the maintenance of the product in the production, transportation, storage and application of the whole process will not be environmental pollution, corrosion, scratch, maintain the original smooth and soft surface, and then improve the quality of products and competitiveness.

The mechanical equipment function of PET maintenance film is high quality, its strong ductility is the best of all thermoplastics, the tensile strength and impact resistance compressive strength is much higher than the general plastic film, PE maintenance film is a more comprehensive packaging film.
