What is breathable film?

Breathable film is a kind of environmental protection breathable (vapor) water (liquid, bacteria, dust) functional material. The emergence of microporous breathable film has a history of more than 20 years, and has been rapidly developed in the past 10 years.

The breathable film is the necessary material for the diaper. The diaper structure is divided into 3 layers: top sheet, absorption core layer and back sheet.

The top sheet of diapers is made of non-woven fabric, the absorption core layer is a polymer absorbent resin and fluff pulp, and the back sheet material is mainly made of PE film or PE film + non-woven fabric, the main purpose of PE breathable bottom film is to prevent urine leakage.

Polyolefin breathable film, which is prepared by adding inert filler to PE or PP carrier, is made by film making and stretching. And use for personal hygiene care products. Breathable film is an upgrade of ordinary waterproof film. Breathable film and ordinary film can not be replaced simply, whether the structural design of the final product is reasonable or not is crucial to the embodiment of the permeability effect of the breathable film!

The so-called breathable film is a functional inorganic product uniformly added into the polyolefin raw material, the product in the film formation process due to high tensile pores, so that it has the function of air permeability and moisture conduction. In short, the function of the breathable film is water insulation, breathable (moisture).
