Abstract: The present invention provides multilayer films and packages formed from such films. In one aspect, a multilayer film comprises an outer layer, the outer layer comprising a polyethylene having a density of 0.930 g/cm3 or greater and 0.01 to 1 weight percent of an additive, based on the total weight of the polyethylene composition, the additive comprising either a sorbitol acetal derivative or a bisamide as specified, wherein the outer layer has a 50% seal strength temperature at least 10° C. greater than an outer layer in a comparative film that differs only in the absence of the additive in the outer layer, when sealed to itself at a pressure of 5 bar with a dwell time of 0.5 seconds.

Abstract: Provided are multilayer films including ethylene-based copolymers. The multilayer films can be fully compatible with polyethylene recycling streams. The multilayer films comprise a first outer layer, a second outer layer, and a core, the core including a first core layer that includes an ethylene-based copolymer selected from the group consisting of ethylene/butyl acrylate copolymer, ethylene/ethyl acrylate copolymer, ethylene/methyl acrylate copolymer, and ethylene/vinyl acetate copolymer. The first core layer according to embodiments disclosed herein is less than 20% of the total thickness of the multilayer film. The multilayer films of the present invention can exhibit improved or desirable properties, such as high tear resistance, in comparison to existing multilayer film structures.
