Abstract: A disposable diaper (1) having a liquid pervious topsheet (2), a liquid impervious and vapor pervious backsheet (3) and an absorbent core (4) interposed between the topsheet and the backsheet includes liquid impervious and vapor pervious barrier sheets (11) between the topsheet and the backsheet, said barrier sheets being extended from the front edge and the rear edge of the diaper to inwards of the front edge and the rear edge of the absorbent core respectively, to thereby form waist barrier parts covering the front edge and the rear edge of the absorbent core, and said barrier sheets being so formed that the strength in the lateral direction of the diaper is higher than the strength in the longitudinal direction of the diaper.

Abstract: The wrapping film of the present invention has a sticky surface, convexities, and flat portions of film disposed between the convexities on at least one side, and comprises at least one agent selected from the group consisting of a surface active agent, an adhesive agent, and an oily agent. The wrapping film has a shear adhesion strength of at most 400 cN/25 cm2 when measured subsequent to bringing said sticky surface into contact with a glass surface having a surface roughness of from 0.7 to 1.5 nm under a pressure of 4 Pa, a shear adhesion strength of at least 700 cN/25 cm2 when measured subsequent to bringing said sticky surface into contact with said glass surface under a pressure of 4 kPa, and the ratio of the height of the convexities to the thickness of the flat portion ranges from 0.03 to 1.67. The wrapping film may also have a surface with a roughness and waviness (Ra') of at least 40 nm as measured in a non-extended state, and an elongation at break of at least 10%.
