Abstract
A process for making a corrugated stretch laminate comprising the steps of providing a first carrier web having a first surface and a second surface; applying a first elastomeric composition in a fluid or molten state to the first surface of the carrier web to form at least one first elastic member; incrementally stretching in a first direction at least a portion of the carrier web to form a stretch composite preform; elongating the stretch composite preform in the first direction; joining a first substrate to the elongated stretch composite preform; and allowing the elongated stretch composite preform to recover to form said corrugated stretch laminate.
