Abstract:
A sealable film comprising:(a) a core layer comprising an olefin polymer wherein the core layer comprises an interior of the film; (b) a separable layer exterior to the core layer, wherein the separable layer comprises a material or blend selected from the group consisting of impact copolymers, thermoplastic polyolefins, block copolymers, blends of impact copolymers and LLDPE's, blends of two or more incompatible polymers, and mixtures thereof; (c) an optic improving layer exterior to both the core layer and the separable layer, wherein the optic improving layer comprises a polymer having at least one of modulus, hardness, and beam strength being higher than to material of the separable layer; and (d) a sealing layer exterior to the core layer, the separable layer, and the optic improving layer, wherein the sealing layer comprises a polymer.
