A stretch laminate comprising an elastomeric film layer and a nonwoven web layer is disclosed. An adhesive is disposed between the elastic film layer and the nonwoven web layer. The elastomeric film layer may include a plasticizer and greater than 7 percent by weight of a tackifier. The elastomeric film formulation provides reduced loss of adhesion strength with the adhesive over time, providing for improvement in mechanical performance of the stretch laminate over time.
