    Abstract: Embodiments of the present invention relate to compositions, multilayer films, and articles. In one aspect, a composition comprises (a) an ionomer that is an acid copolymer comprising ethylene and at least one of acrylic acid and methacrylic acid, wherein a portion of the acid groups in the acid copolymer are neutralized by metal ions and are carboxylic acid salts, and wherein the acid copolymer, prior to neutralization of acid groups by metal ions, comprises 5 to 30 weight percent of acrylic acid and methacrylic acid; (b) an ethylene/unsaturated ester copolymer comprising ethylene vinyl acetate, ethylene acrylate, or a combination thereof; and (c) a propylene-based polymer comprising a copolymer of propylene and a comonomer comprising ethylene, butene, hexene, or octene, wherein the propylene-based polymer has a molecular weight distribution (MWD) of less than 3.0, and a viscosity ratio (viscosity at 0.1 s-1/viscosity at 100 s-1) of greater than 7.0.

    Abstract: The present disclosure provides a composition containing a polymeric blend. The polymeric blend contains (A) from 50 wt% to 90 wt% of a first ethylene-based polymer having a density from 0.895 g/cc to 0.905 g/cc; and a melt index from 0.1 g/10 min to 50 g/10 min; (B) from 8 wt% to 48 wt% of a second ethylene-based polymer having a density from 0.935 g/cc to 0.967 g/cc; and a melt index from 0.1 g/10 min to 180 g/10 min; and from 0.01 wt% to 2.0 wt% of a slip agent, based on the total weight of the polymeric blend. The polymeric blend has (i) an overall density from 0.900 g/cc to 0.925 g/cc; and (ii) a coefficient of friction (COF) after aging for 1 week at 60°C from 0.001 to 0.400. The present disclosure also provides a multilayer film with a first layer containing the composition.
