Patent ID: 7422796

Claim:
A monolithic film obtained from a blend consisting essentially of: (a) one or more aliphatic organic acids or salts thereof having fewer than 36 carbon atoms; (b) at least one E/X/Y copolymer (ethylene acid copolymer) wherein E is derived from ethylene, X is derived from at least one C 3 to C 8 α,β-ethylenically unsaturated carboxylic acid, and Y is derived from a comonomer selected from alkyl acrylates and alkyl methacrylates, wherein the alkyl groups have from 1 to 8 carbon atoms, or ionomers of said E/X/Y copolymers, wherein X is from about 3 to about 30 weight % of said E/X/Y copolymer, and Y is from 0 to about 35 weight % of said E/X/Y copolymer, and wherein greater than 70% of all the total acid moieties from (a) plus (b) are neutralized to the corresponding metal salts; and (c) at least one additional polymer selected from the group consisting of: silicone-containing polymers and ethylene copolymers having comonomer units selected from the group consisting of alkyl acrylates, alkyl methacrylates, carbon monoxide, vinyl acetate, maleic anhydride, maleic anhydride derivatives and mixtures thereof.
