The Difference Between PET Protective Film And PE Protective Film

The difference between PET protective film and PE protective film


PET protective film is also known as film high temperature polyester film. It has excellent physical properties, chemical properties and dimensional stability, transparency, recyclability, can be widely used in magnetic recording, photosensitive materials, electronics, electrical insulation, industrial film, packaging and decoration and other fields. It can be made into mobile phone liquid crystal protection film, LCD TV protective film, mobile phone button and so on.


PE protective film is based on special polyethylene (PE) plastic film as the substrate, according to the different density of high-density polyethylene protective film, medium-density polyethylene and low-density polyethylene. PE protective film is the most simple structure of polymer organic compounds, the world's most widely used polymer materials. Its greatest advantage is that the protected products are not polluted, corroded and scratched in the process of production, processing, transportation, storage and use, so as to protect the original bright surface, thereby improving the quality of products and market competitiveness.


PET protective film has excellent mechanical properties, its strength and toughness is the best of all thermoplastic, tensile strength and impact strength than the general film is much higher;


PE protective film is a relatively comprehensive packaging film. It has good transparency and luster, good air tightness and aroma retention, moderate moisture resistance, moisture permeability at low temperature decreased.


From the above understanding of the PE protective film and PET protective film of some basic knowledge, we can clearly know the difference between them, in addition, PE is softer, PET is harder; pick up and shake, PE silent, PET has sound; PE tensile strength is not as good as PET; PE protective film temperature is generally 60 degrees, and PET protective film can be 120 degrees or more. So choose different material protection films for different products when choosing.
