BACK SHEET FOR ABSORPTIVE ARTICLE

摘要

PROBLEM TO BE SOLVED: To provide a back sheet for an absorptive article which has moisture permeability and tear strength properties in combination with good balance and is capable of preventing peeling of a moisture permeable film and a nonwoven fabric in rewearing of the absorptive article or peeling after use. SOLUTION: The back sheet 2 of the absorptive article 1 constituted by interposing an absorber 4 between a liquid permeable top sheet 3 and the liquid impermeable back sheet 2 laminated with the moisture permeable film and the nonwoven fabric and forming tacky adhesive layers 10 and 11 for non- slipping on the underwear contact surface side of the back sheet 2 is the composite sheet formed by laminating the moisture permeable film of >=3,000 g/m<2> .24 hr in moisture vapor transmission rate in the moisture permeability test complying with JIS Z 0208 and the nonwoven fabric of >=2,940 mN tear strength in the tear test complying with JIS L 1096. The moisture permeable film and nonwoven fabric described above are joined at peeling strength of >=980 mN/25 mm.
