Abstract:
Multilayer thermoplastic films, and laminates and articles comprising the films, wherein the film comprises at least one inner layer and at least two outer layers, wherein the inner layer comprises a polymeric composition comprising from about 55% to about 95% of one or more non-hydrogenated styrenic block copolymers, olefinic block copolymers, or combinations thereo; and each outer layer comprises at least 20% polypropylene and has a thickness of from about 5% to about 15% of the total film thickness, and further wherein the film has a constant force tear propagation of about 20% or less.
