Absorbent core

Abstract

An absorbent core structure for disposable absorbent articles. The absorbent core having improved fluid handling properties. The absorbent core includes a first layer, a layer of absorbent polymer material, a layer of adhesive, and a second layer. The first layer has a first surface, a second surface, and a thickness of 0.4 mm to 1.5 mm.
