Abstract
An absorbent pad having elasticized side flaps is adapted to provide improved leakage performance and comfort. In one embodiment, the elastic member of each side flap is at least partly out of the plane of the absorbent assembly when the absorbent pad is in a generally flat position, and the absorbent pad has a Gurley stiffness of greater than 2000 milligrams. In another embodiment, the absorbent pad has an anti-roll back feature and an Effective Elastic Value of at least 30 millimeters.
