Abstract

Disclosed is an absorbent article having a liquid pervious topsheet, a liquid impervious backsheet joined to the topsheet, and an absorbent core positioned therebetween, in which the absorbent core is enveloped by a primary core integrity layer comprising a continuous mesh of strands of thermoplastic material which is joined to the topsheet and/or the backsheet. The primary core integrity layer is particularly useful for improving the wet integrity of absorbent cores comprising an upper acquisition/distribution layer and a lower storage layer.
