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.
