A polymeric film or sheet comprising (i) an ionomeric composition comprising an ionomeric copolymer of an alpha-olefin and about 1 to about 30% by weight of an alpha, beta-ethylenically unsaturated carboxylic acid having 3 to 8 carbons, based in the total weight of the ionomeric copolymer, wherein the carboxylic acid is neutralized to a ferrel of 1 to 100 mol%, with one or more metal ions, based on the total number of moles of carboxylate groups in the ionomeric copolymer, and in wherein the ionomeric copolymer has a melt index of about 20 to about 300 g / 10 min, and (ii) about 0.5 to about 3% by weight of organic peroxide, based on the total weight of the ionomeric composition. |
