Diapers mainly consist of pe and non-woven fabrics and absorbent wood pulp. In general, pe films are airtight, and only non-woven fabrics are breathable. If pe film breathable diapers leak urine, many diapers will prevent side leakage. The pe film of the diaper extends to the edge portion, so that the moisture inside the diaper is very difficult to discharge, so when using the diaper, try to use the narrow brand of the diaper.
