Abstract
A flexible absorbent pad has a dry thickness of between 2 mm and 10 mm and a difference in flexural-resistance between the dry state and the wet state of an absorbent center zone of the absorbent pad of less than 100 grams-force. The absorbent core of the pad may include an airlaid, a foam, or a fibrous staple filament. The absorbent core of the absorbent pad may be corrugated, such as with flexure hinges, in which case adhesive is applied to the backsheet of the absorbent pad in a pattern that leaves the flexure hinges devoid of adhesive so that the backsheet is attached to the absorbent core in a manner that does not impede the flexing of the flexure hinges.
