Abstract

An absorbent article comprising an absorbent core being enclosed by a liquid-permeable core cover comprising an upper core cover layer and a lower core cover layer and having a longitudinal center line. The absorbent core has a pair of longitudinally extending side edges and a pair of transversely extending end edges. The core cover layers are connected inside seals extending along the side edges of the absorbent core. The absorbent core comprises one or more longitudinally extending channels arranged at a distance from the side seals, each of the one or more channels being free or substantially free from absorbent material and having a channel seal extending therein. The channel seal joins the upper and lower core cover layers of the core cover within the channel, with a seal strength of the channel seal being higher than a seal strength of each of the first and the second side seals of the absorbent core.
