In our industry, we often talk about PE protective film or PE release film. So, What is the difference between PE protective film or PE release film? Today, the editor will discuss with everyone. Firstly, let's talk about the purpose. PE protective film is used for initial and factory protection on the surface of electronic products, while PE release film is a disposable consumable used for the protection of raw materials in production and the discharge of waste in the process.

The advantage of PE protective film is that the protected product is not contaminated, corroded, or scratched during production, processing, transportation, storage, and use; Protect the original smooth and shiny surface, thereby improving product quality and market competitiveness.

PE release film is a widely used polymer material in the world today, made from ethylene polymerization. PE release film is divided into high-density polyethylene, medium density polyethylene, and low-density polyethylene. Low density polyethylene is relatively soft and is often polymerized under high pressure; High density polyethylene has the characteristics of rigidity, hardness, and high mechanical strength, and is commonly used for low-pressure polymerization. High density polyethylene can be used as containers, pipelines, and high-frequency electrical insulation materials for radar and television.

Low density (high-pressure) polyethylene is commonly used in large quantities. Polyethylene is waxy and has the same smooth feeling as wax. When it is not dyed, low-density polyethylene is transparent, while high-density polyethylene is opaque. Polyethylene is a high polymer chain connected by repeated - CH2- units through the Addition reaction and polymerization of ethylene. The performance of polyethylene depends on its polymerization method. High density polyethylene is produced by Ziegler Natta polymerization of organic compounds under medium pressure (15-30 atmospheric pressure) catalytic conditions. If free radical polymerization is carried out under high pressure (100-300MPa), high temperature (190-210 C), and peroxide catalyzed conditions, low-density polyethylene is produced.
