CPE membrane working principle analysis


Abstract

This article will introduce the working principle of CPE membrane and explain its role and characteristics in different application fields.
CPE film, namely chlorinated polyethylene film, is a kind of polymer film material with excellent properties. CPE film is mainly composed of ethylene chloride and ethylene copolymer, so the film has good mechanical properties and chemical resistance. CPE film is widely used in industrial production, building insulation, food packaging and other fields. Its working principle is mainly reflected in the following aspects.
First, the CPE film has excellent barrier properties. Its molecular structure is closely arranged, forming a relatively dense structure, which can effectively block the penetration of gas, water vapor and other substances, thereby protecting the quality and freshness of packaged goods.
Secondly, the CPE film has good aging resistance. Due to the physical structure and chemical composition of the material, the CPE film has strong weather resistance and heat resistance, and is not susceptible to aging and deterioration due to external environmental factors.
In addition, CPE film has good molding processing performance, can be molded into different shapes of packaging products in the heated state, to meet various needs. The shaping process is simple, the production efficiency is high, and the cost is low.
In summary, CPE film, as an important polymer material, has excellent barrier properties, aging resistance and molding processability, and is widely used in various fields, bringing convenience and reliability to the packaging industry, construction industry, etc. Solution.
