Abstract

A stretch laminate includes a first layer including an elastomer film, the first layer having a surface, and a second layer including a nonwoven material, the second layer having a surface that is attached to the surface of the first layer. The tensile behavior in the transverse direction of the stretch laminate is within about 2.5 N/cm of the tensile behavior in the transverse direction of the film at an engineering strain of about 1.5, and exists independent of mechanical activation. A method of making the stretch laminate and an absorbent article having at least one region defined by the stretch laminate are also provided.
