Abstract
An absorbent article comprises an absorbent core sandwiched between a liquid-permeable topsheet and a liquid-impermeable backsheet. The article comprises front, back and crotch portions. The absorbent core comprises an absorbent component having a width in the transversal direction and the absorbent component is enclosed by a core cover comprising an upper side and a lower side. Two channel sealings extend along the longitudinal axis in the crotch portion for joining the upper and lower side of the core cover. A core cover, which is arranged around the absorbent component, defines and limits an expansion space for the centre segment so that the centre segment is prevented from reaching complete expansion to the second volume on wetting, and the ratio of the first width of the centre segment and the width of the absorbent component, in dry condition, is 0.25-0.45.
