Abstract

An absorbent article comprising a liquid permeable topsheet, a backsheet, an absorbent core comprising an absorbent material and a core wrap is provided. The core comprises at least one channel-forming area that is substantially free of absorbent material. The absorbent article comprises a masking layer between the bottom side of the core wrap and the backsheet. The masking layer and the bottom side of the core wrap are only partially bonded to each other at their interface, the interface thus comprising a bonded portion and an unbonded portion, wherein the channel-forming area at least partially corresponds to the unbonded portion of the interface, so that when the absorbent material swells, the masking layer can decouple from the three-dimensional channels.
