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 it is good to use a narrow plaque when choosing a diaper, so that the child is not prone to heat.
