Abstract
An absorbent article has a liquid pervious topsheet, a liquid impervious backsheet, an absorbent core disposed between the topsheet and backsheet; first and second opposing longitudinal side edges, a front waist region and a back waist region; and a first and second back ear extending outwardly from the first and longitudinal side edges in the back waist region, respectively. The first and second back ears have an engineering strain greater than about 8% at about or below 2N of force when measured according to the Back Ear Extension Test, and a roughness Ra lower than about 300 μm when measured according to the Roughness Test.
