Abstract
An absorbent article may comprise a topsheet, a backsheet joined with the topsheet, an absorbent core interposed between the topsheet and backsheet; and a slow recovery stretch laminate. The slow recovery stretch laminate may be joined to one or more article elements selected from the group consisting of the topsheet, the backsheet, the core, an anal cuff, an elasticized topsheet, a fastening system, a leg cuff, a waist elastic feature, a side panel, an ear, and combinations thereof. The slow recovery stretch laminate may exhibit an unload force at 37° C. of about 0.16 N/(g/m) or greater and a percent of initial strain after 15 seconds of recovery at 22° C. of about 10% or greater. And, the slow recovery stretch laminate may comprise an elastic member that was pretreated prior to and/or during draw down of the elastic member.
