Multilayer films including ethylene-based copolymers

A multilayer film comprising:

• a first outer layer, a second outer layer, and a core, the core comprising one or more core layers;
• wherein the core is positioned between the first outer layer and the second outer layer;
• wherein the core comprises greater than 90 wt. % ethylene-based polymers, based on the total polymer weight of the core;
• and wherein a first core layer comprises 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;
• wherein the first outer layer and second outer layer each comprise an ultra low density polyethylene (ULDPE), low density polyethylene (LDPE), polyethylene plastomer/elastomer, linear low density polyethylene (LLDPE), medium density polyethylene (MDPE), high density polyethylene (HDPE), olefin block copolymer, or combinations thereof;
• wherein the first core layer is from 5 to less than 20% of the total thickness of the multilayer film;
• wherein the multilayer film has a cross direction tear resistance of at least 25.0 g/μm.
