Abstract
A disposable absorbent article having a topsheet, a backsheet, an absorbent core structure disposed between the topsheet and backsheet, and a flex bond channel region. The absorbent core structure includes an upper nonwoven layer having polymer fibers, a lower nonwoven layer having polymer fibers, and an inner core layer disposed between the upper and lower nonwoven layers. The flex bond channel region has a dry channel depth of from about 1.0 mm to about 4.5 mm and a channel width of from about 1.0 mm to about 3.0 mm. The flex bond channel region has a Dry MD Bending Resistance of less than about 0.04 N / mm. The inner core layer comprises an outer absorbent zone that substantially surrounds a central absorbent zone. The basis weight of the central absorbent zone is greater than the basis weight of the outer absorbent zone.
