Detailed Introduction


The breathable film backsheet uses PE as a carrier, adds a certain proportion of CaCO3 to form and stretches, so that the breathable film has a unique microporous structure. There are thousands of nano-level breathable micropores distributed on each square centimeter of the film. These special micropores with high density on the film can not only block the leakage of liquid, but also allow water vapor molecules to pass smoothly. Therefore, it has the function of being breathable and impermeable. It is called a "breathable film" and makes the skin drier and more comfortable. At the same time, the breathable film is also soft to the touch, non-toxic, white and high in purity. Breathable film backsheet is used in high grade sanitary napkin backsheet.
