How are film materials used in sanitary products?

Lively

The main applications of film materials in sanitary products are sanitary napkin wrap, sanitary napkin base layer and diaper base layer, which include breathable and non-breathable films. The bottom layer of sanitary napkins and diapers in the Chinese market has generally used breathable film, which is more conducive to keeping the skin dry and improving the dryness and breathability of the products. The bottom layer of diapers basically uses breathable film and non-woven composite imitation cloth bottom film. The imitation cloth bottom film feels soft like cloth, which is more conducive to keeping the skin dry and is thinner, so there is no frictional sound when the baby moves. Sanitary napkin products are generally wrapped in non-breathable film.
