What is the difference between PET protective film and PE protective film?-film supplier

In recent years, the rapid development of the middle and downstream industries of electronic communication, digital and other adhesive products and protective films will drive a new round of huge demand in the adhesive and protective film industries. From the perspective of industry products and exhibited products at the PET exhibition, most of the tape companies are transforming from ordinary tapes to industrial tapes, while film companies are developing from ordinary PE protective films to high-end films or optical films. This is exactly what the development of the electronics industry has played. Leading role. Now there are two kinds of protective films on the market, PET protective film and PE protective film. Let’s talk about the difference between these two protective films? 　 　 Let’s talk about PET protective film first. 　　 PET protective film is also known as high temperature resistant polyester film. It has excellent physical properties, chemical properties, dimensional stability, transparency, and recyclability, and can be widely used in magnetic recording, photosensitive materials, electronics, electrical insulation, industrial films, packaging decoration and other fields. Can be produced into mobile phone LCD protective film, LCD TV protective film, mobile phone buttons, etc. PET protective film has excellent mechanical properties, its strength and toughness are the best among all thermoplastics, and its tensile strength and impact strength are much higher than ordinary films; 　　 After introducing PET protective film, let’s talk about PE protective film PE protection The film is based on a special polyethylene (PE) plastic film, and is divided into high-density polyethylene protective film, medium-density polyethylene and low-density polyethylene according to the density. PE protective film is the simplest polymer organic compound and the most widely used polymer material in the world today. Its biggest advantage is that the protected product is not polluted, corroded, scratched during production, processing, transportation, storage and use, and protects the original smooth and shiny surface, thereby improving the quality of the product and the market competitiveness.　　 PE protective film is a kind of packaging film with more comprehensive performance. It has good transparency and luster; it has good air tightness and fragrance retention; it has medium moisture resistance, and its moisture permeability decreases at low temperatures. PE protective film is a simple polymer organic compound, a polymer material widely used in the world today. PE protective film uses special polyethylene (PE) plastic film as the base material. According to the density, it is divided into high-density polyethylene protective film, medium-density polyethylene and low-density polyethylene.　　 PE protective film use: protect the product from pollution, corrosion, scratches during production, processing, transportation, storage and use, and protect the original smooth and shiny surface, thereby improving product quality and market competitiveness.　　 PE is softer, PET is harder; when picked up and shaken, PE has no noise, PET has noise; PE tensile strength is not as good as PET; PE protective film temperature resistance is generally 60 degrees, while PET protective film can be 120 degrees and above. Therefore, when choosing, choose different material protective films for different products. Therefore, the difference between PET protective film and PE protective film is different in terms of advantages and disadvantages, performance, and application fields.
