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.
