Absorbent article with ear portion
An absorbent article includes a first waist region, a second waist region and a crotch region disposed between the first and second waist regions. The absorbent article further includes a topsheet, a backsheet, an absorbent core disposed between the topsheet and the backsheet, and a laminate. The laminate has an elasticized region. The laminate includes a first nonwoven, a second nonwoven and an elastomeric material sandwiched between said first and second nonwovens in the elasticized region. The laminate includes a bonding region with a bond density of at least 4% and at least partially overlapping the elastomeric material. The laminate exhibits an Unload Force at 50% of at least 0.90 N.
