WIPO Patent Application WO/2018/128178
Kind Code:
A1
Abstract:
The present invention can reduce the extension stress of an absorbent article so that the absorbent article can easily stretch, and can improve the breathability and increase the maximum elongation to at or above a prescribed value. Provided is an absorbent article (1) comprising a stretch region, wherein the stretch region of the absorbent article (1) is made of an elastic sheet in which a first non-stretchable sheet (21), an elastic film (23), and a second non-stretchable sheet (22) are laminated in this order. In the elastic sheet, a plurality of bonding/opening parts (51-55) are formed by bonding parts (51a-55a) that bond the first non-stretchable sheet (21) and the second non-stretchable sheet (22), and opening parts (51b-55b) that are generated in the elastic film (23) by the formation of the bonding parts (51a-55a). The bonding/opening parts (52-55) form adjacent bonding/opening parts (50A, 50B) composed of a plurality of adjacent bonding/opening parts.
