When used as a water-proof material, the safety (water-proof property) of the breathable membrane is the premise, and only under the premise of ensuring safety can we talk about breathability;

The manufacture of microporous breathable membranes can be divided into blown film method and cast method according to different film making processes; according to different stretching processes, it can be divided into unidirectional stretching method, bidirectional stretching method and partial stretching method.

When the water vapor concentration on one side of the membrane is greater than the environment on the other side of the membrane, a humidity gradient pressure difference is formed.

PE film, that is, polyethylene film, refers to a film produced with PE particles. PE film has moisture resistance and low moisture permeability. Polyethylene film (PE) can produce products with different properties such as low-density, medium-density, high-density polyethylene and cross-linked polyethylene according to different manufacturing methods and control methods.

In fact, breathable membrane is not unfamiliar to us. PE film generally refers to the PE functional material with environmental protection, waterproof and breathable. It is mainly used for the bottom film of women’s sanitary napkins, the bottom film of panty liners, the bottom film of baby diapers, etc., and it is composited with non-woven fabrics.

In recent years, the PE breathable membrane has been developing continuously. In recent years, with the development of science and technology, the PE breathable membrane has also been continuously improving technical problems, and the air permeability and waterproof effect are getting better and better.

Guangdong Huaping Hygiene Material Industrial Co.,Ltd. main products include PE protective film,PE breathable film,PE perforated film,Multicolor printed film,Nonwoven Laminated film,Anti-counterfeiting Holographic film etc .We have introduced the main crystal point types, identification methods, causes and countermeasures in detail above. It can be summed up as follows:

PE protective film series of products produced by Huaping are widely used in personal hygiene care,such as sanitary napkins PE film,sanitary pads PE film,adult diapers,protective clothing,cosmetic medical supplies and other disposable items.

In daily life, PE protective film is relatively common in the protective film market, and it is used in many fields, especially in the protection of products during production, processing, transportation, etc., so that the product will not be damaged during use.
