Waterproof breathable film is mainly composed of three layers: PP spunbond non-woven fabric, PE polymer breathable film, PP spunbond non-woven fabric. The main function of spunbond non-woven fabric is to enhance the tension and hydrostatic pressure and protect the middle layer (permeability film), the real permeability is mainly by the middle layer PE polymer permeability film.
Fengflexibles using WH five layer blowing film belt unidirectional stretching equipment and special process formula, the production of high permeability and moisture permeability of the breathable film, customer service of the general polymer can not be wet shortcomings.
