Abstract

absorbent article comprising a liquid transfer layer (5) positioned between a liquid pervious bodyside liner (6) and an absorbent core (2). The liner (6) comprises a plurality of perforations (7). The liner and the transfer layer are bonded together in a plurality of bonding sites (11) covering an area of between 0.5% and 11% of the area of the liner (6) that is circumscribed by the bonding sites and wherein each bonding site has an area of no more than 13 mm2. The combined perforated liner (6) and transfer layer (5) provides a quick inlet of liquid and a low rewet against the wearer. The liner (6) has a three-dimensional structure of alternating raised and depressed regions and the perforations (7) are present in the bottoms of the depressions (8) of said liner as seen from the body facing side of the liner.
