Abstract
Abstract Absorbent article such as disposable diapers, incontinent briefs, diaper holders, and the like, that have a unique composite member forming a portion of the elasticized side panel and the elasticized waistband. The composite member includes an elastomeric member and a three-dimensional, macroscopically expanded, formed-film member secured to at least one of the surfaces of the elastomeric member. The composite member provides the preferred bulk, elasticity, resiliency, and stiffness required to withstand the application, wear and removal stresses and provide the desired comfort during the typical wearing cycle of a disposable diaper.
