Which is better, PE protective film or PET protective film?

Recently, I often receive such calls: Which is better, PE protective film or PET protective film? Every time I face such a phone call, I will always patiently explain it to them. Here I will share my opinions with you again. The PE protective film is made of polyethylene plastic film as the base material, cross-linked polyacrylic acid resin as the adhesive, and several special additives are added to prepare and debug. The glue is colorless, transparent, soft and sticky, the color specifications of the products are various, the printing is exquisite, and can be specially customized according to the requirements of customers. The adhesion and specifications of different product models can be selected for the protection of different material surfaces. Products are widely used in: Aluminum-plastic plate, nameplate, metal surface, plastic plate surface, building decoration materials, polyester furniture, stone, stainless steel, automobile interior decoration, aluminum alloy, plexiglass, electronics, household appliances, surface protection of products in IT and other industries. Color Category: PE transparent protective film, PE black and white protective film, PE blue protective film, PE milky white protective film, PE red protective film, etc. The PET protective film is composed of transparent polyester film plus carbon element and special protective film glue. The surface is hardened for 3 hours, and the surface hardening treatment of the material has good weather resistance, it has low adhesion and is easy to tear, and has ultra-high light transmittance optical effect. After removal, there is no residual glue, and it has a special design that is not easy to cover the air and generate bubbles. 1. From the material point of view, PE protective film is relatively soft and PET film is relatively tough. It is a protective film of two different materials. 2, from the tensile rate, PE film has good extensibility, elongation from 150- 300%, can achieve different effects for different purposes. PET film has no extensibility, is not easy to deform, and has good hardness. 3. From the perspective of usage, PE protective film is suitable for aluminum-plastic plate, nameplate, metal surface, plastic plate surface, building decoration materials, polyester furniture, stone, stainless steel, automobile interior decoration, aluminum alloy, plexiglass, electronics, household appliances, IT, etc product surface protection in the industry; PET protective film is suitable for TV screen, notebook computer screen, PDA handheld computer screen, LCD screen, PSP game console LCD screen, electronic dictionary LCD screen, mobile phone, digital camera, camera screen, vehicle DVD display screen, GPS LCD protection and so on.
