发明名称 Combination of elastomeric film composition and adhesive for a stretch laminate
摘要 A structure comprising an elastic film layer and an adhesive in contact therewith is disclosed. 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.
