What is the difference between PET release film and PE release film, but their functions and uses are not the same? What is the difference between PET release film and PE release film. Before understanding the differences between PET release films and PE release films, it is important to first understand their respective characteristics and applications.

PET release film, also known as high-temperature resistant polyester film. It has excellent physical and chemical properties, dimensional stability, transparency, and recyclability, and can be widely used in fields such as magnetic recording, photosensitive materials, electronics, electrical insulation, industrial films, packaging and decoration. It can be produced into mobile phone LCD protective film, LCD TV protective film, mobile phone buttons, etc.

PE release film is made of special polyethylene (PE) plastic film as the substrate, and is divided into high-density polyethylene protective film, medium density polyethylene, and low density polyethylene according to different densities. PE release film is a polymer organic compound with a simple structure and is widely used as a polymer material in the world today. Its advantage is that the protected product is not contaminated, corroded, scratched during production, processing, transportation, storage, and use, protecting the original smooth and shiny surface, thereby improving the quality and market competitiveness of the product.

The mechanical properties of PET release film are excellent, and its strength and toughness are relatively good among all thermoplastic plastics. The tensile strength and impact strength are much higher than general films; PE release film is a packaging film with relatively complete performance. It has good transparency and luster; Has good airtightness and fragrance retention; Moderate moisture resistance, with a decrease in moisture permeability at low temperatures.

From the above understanding of some basic knowledge about PE release film and PET release film, we can clearly understand their differences. In addition, PE is softer while PET is harder; When lifted and shaken, there is no sound from PE, while there is a sound from PET; The tensile strength of PE is not as good as that of PET; The temperature resistance of the  is generally 60 degrees, and PET release film can be120 degrees and above.
