Abstract:
Provided is a multilayer co-extruded film comprising at least two different elasticity layers with at least one first elasticity layer and at least one second elasticity layer having higher elasticity than the at least one first elasticity layer, wherein the first elasticity layer comprises a combination of an olefin-based elastomer and a crystalline olefin polymer, and wherein the residual strain after 100% elongation during 10 min at 23° C. of the multilayer co-extruded film is less than 15%.
