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 article comprises an intermediate layer between the bottom side of the core wrap and the backsheet. The intermediate layer and the absorbent core are only partially bonded to each other at their interface and the interface comprises a bonded portion and a unbonded portion. The intermediate layer can at least partially decouple from the absorbent core in the unbonded portion, which increases flexibility of the article in the transversal direction.
