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 film, LCD TV protective film, mobile phone buttons, etc.
PE protective film is based on a special polyethylene (PE) plastic film, which 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 products are not polluted, corroded, scratched during production, processing, transportation, storage and use, and protect the original smooth and shiny surface, 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 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.
From the above understanding of some basic knowledge of PE protective film and PET protective film, you can clearly know the difference between them. In addition, PE is softer and PET is harder; when it is shaken, there is no sound from PE, but no sound from PET; The tensile strength of PE is not as good as PET; the temperature resistance of PE protective film is generally 60 degrees, while the temperature of PET protective film can be 120 degrees and above. Therefore, when choosing different products, choose different material protective films.
