Abstract
Absorbent laminates and multi-layer, folded absorbent cores comprising the absorbent laminates for use in absorbent articles are presented. Specifically, multi-layer, folded absorbent cores are presented that are formed from an absorbent laminate comprising an absorbent layer between two tissue layers, in which the absorbent core includes a central channel running longitudinally along the core and crenellations profiled along the thickness of the core and providing enhanced liquid distribution across the core surface area or profile and improved liquid absorption into the laminate.

An absorbent core comprising a longitudinally folded absorbent laminate, the absorbent laminate comprising:
- an upper laminate layer;
- a lower laminate layer;
- and
- an absorbent layer positioned between the upper laminate layer and the lower laminate layer, the absorbent layer comprising greater than about 90 percent by weight super absorbent polymer (SAP).
An absorbent core comprising a longitudinally folded multi-layer absorbent laminate the absorbent laminate comprising:
- an upper laminate layer;
- a lower laminate layer;
- and
- an absorbent layer positioned between the upper laminate layer and the lower laminate layer, the absorbent layer containing SAP;
- wherein the absorbent laminate is folded to form a longitudinally folded multi-layer absorbent laminate of at least three layers.
An absorbent core comprising a longitudinally folded multi-layer absorbent laminate the absorbent laminate comprising:
- a substrate laminate layer;
- and
- an absorbent layer positioned and adhered on the substrate laminate layer, the absorbent layer containing SAP;
- wherein the absorbent laminate is folded to form a longitudinally folded multi-layer absorbent laminate of at least three layers.
