breathable film for diaper
Breathable film for diaper is an environmentally friendly, breathable (steam) and water-proof (liquid, bacteria, dust) functional material. The emergence of microporous breathable membrane has a history of more than 20 years, and it has developed rapidly in the past 10 years. China is at the initial stage in terms of technology, market and application. Breathable film is a functional inorganic product that is uniformly added to the polyolefin raw material, so that the product will have pores due to high stretching during the film forming process, so that it has the function of breathability and moisture conduction. The water absorption of a general breathable membrane has its limit. When the water absorption exceeds the limit that the breathable membrane can carry, the water-proof effect of the breathable membrane will lose its effect.
