1. A film structure comprising:
(a) at least one functionalized film layer, wherein the at least one functionalized film layer comprises a polar-reactive group polyolefin layer used as an internal lamination layer in the film structure; wherein the polar-reactive group polyolefin layer consists of a physical blend of an ethylene vinyl acetate polar copolymer and a grafted ethylene polar copolymer; and wherein the polar-reactive group has a functional group that comprises 0.15 wt. % to 1.5 wt % based on the total weight of the polyolefin layer; and
(b) a lamination adhesive composition present on, and in contact with, a least a portion of a surface of the internal layer;
wherein the chemical resistance value of the lamination adhesive composition is a bond strength sufficient for the laminate to withstand a measured adhesion force of at least 200 g-f/in when the laminate is subjected to a delamination test accompanied by a failure mode of tearing or no failure mode.
