PE Laminated sheet

Diapers are mainly composed of surface covering layer, diversion layer, absorbent core layer, PE Laminated sheet, elastic waist, Velcro, Velcro and hot-melt adhesive bonding all parts together. Absorbent system built from multiple layers of nonwovens. Among them, the leak-proof bottom film of diapers is in direct contact with human skin, and is mainly used to prevent the leakage of urine and play a role of isolation. Therefore, it is required to have the following properties: (1) good gas permeability; (2) Good water leakage resistance; (3) good tensile properties and tear resistance; (4) good flexibility, etc. At present, the leak-proof bottom film of diapers usually adopts PP breathable microporous film or hot-rolled non-woven PE Laminated film. The breathable microporous membrane utilizes the diameter difference between water droplets (20 microns) and water vapor molecules (0.0004 microns), and the pore diameter is in between to make the microporous membrane both breathable and waterproof.
