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 meltblown material which is joined to the topsheet. 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.
