PE breathable film (polyethylene breathable film) has a wide range of applications

PE breathable film, the full name of polyethylene breathable film, is a new type of membrane material based on polyethylene (PE) that is breathable but not water-permeable. Compared with other breathable films, PE breathable films have the advantages of good softness, good air permeability, good moisture permeability, and high tensile strength. They are widely used in many fields such as medical care, daily necessities, electronics and electrical, clothing and textiles, food packaging, etc.

PE breathable film preparation methods include hot pressing composite method, thermally induced phase separation method, cast composite method, hot melt adhesive composite method, etc. Thermal induced phase separation (TIPS) is widely used in the preparation process of PE breathable films. It refers to dissolving polyethylene in diluent under high temperature conditions, and then going through processes such as cooling, phase separation, and extraction to obtain PE breathable films. This method has the advantages of being able to control the structure and shape of the membrane material, adjust the porosity size, and have good finished product quality, and is suitable for continuous production. In recent years, with in-depth research, my country’s thermally induced phase separation technology has gradually matured, which provides favorable conditions for the development of the PE breathable film industry.

The core raw material of PE breathable membrane is polyethylene. Polyethylene is one of the five major synthetic resins. It has the advantages of good chemical stability, non-toxicity, low temperature resistance, lightweight and high toughness. It has broad application prospects in packaging, construction engineering, medicine and other fields. my country is a major consumer of polyethylene, and the industry has been in short supply for a long time, driving its import scale to continue to grow. In recent years, with the increasingly strong market demand, my country’s new polyethylene production capacity has been continuously released. Against this background, the development speed of my country’s PE breathable film industry has accelerated.

According to the “2023-2028 China PE breathable film (polyethylene breathable film) industry market in-depth research and development prospect forecast report》shows that PE breathable films are widely used in many fields such as medical care, daily necessities, electronics and electrical, clothing and textiles, food packaging, etc. In the medical field, PE breathable films can be used to produce medical protective masks, medical protective clothing, etc.; in the field of daily necessities, PE breathable films can be used to produce female sanitary napkins, baby diapers, etc.; in the electronic and electrical fields, PE breathable films can be used as electronic screens. Protective film.

There are many PE breathable film manufacturers in my country, and the market competition is fierce. The main manufacturers include Fo Plastic Technology, Dadongnan, Tianwang Plastics, Polyshi Chemicals, and Hetairunjia. Currently, Huahan Company, a subsidiary of Fosu Technology, is actively promoting the production expansion project of blown PE breathable films and printed films, with a planned investment amount of 80.881 million yuan.

Industry analysts said that as a segmented product of breathable films, PE breathable film has excellent performance and is widely used in many fields. Benefiting from strong market demand and increasing technological maturity, the development speed of my country’s PE breathable film industry has further accelerated. In recent years, attracted by market prospects, the number of companies in my country’s PE breathable film industry has continued to grow. It is expected that companies with independent research and development capabilities for high-performance products will occupy a larger share of the market in the future.
