What is the difference between PET protective film and PE film? Their functions and uses are different. What is the difference between PET protective film and PE protective film? Before understanding the difference between PET protective film and PE protective film, you should first understand their respective characteristics and uses.
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. It can be produced into mobile phone LCD protective films, LCD TV protective films, mobile phone buttons, etc.
PE protective film is based on special polyethylene (PE) plastic film. According to the density, it is divided into three types of high, medium and low density polyethylene PE protective film. It is a polymer organic compound with a relatively simple structure. It is widely used in the world today. A wider range of polymer materials. Its significant advantage is that the protected products are free from contamination, corrosion, and scratches during production, processing, transportation, storage and use, and the original smooth and shiny surface is protected, thereby improving product quality and market competitiveness.
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; PE protective film is a packaging film with relatively complete properties. It has good transparency and gloss; it has good air tightness and fragrance retention; it has medium moisture resistance, and its moisture permeability decreases at low temperatures.
From the above understanding of some basic knowledge of PE protective film and PET protective film, we can clearly know their differences. In addition, PE is softer and PET is harder; when picked up and shaken, PE has no sound but PET has sound; The tensile strength of PE is not as good as that of PET; the temperature resistance of PE protective film is generally 60 degrees, while PET protective film can be 120 degrees and above. Therefore, when choosing, you should choose different material protective films for different products.
