Abstract: The present disclosure is directed to a multilayer film. The multilayer film includes at least three layers, a first layer, a second layer and a third layer. The first layer is formed from a first composition. The first composition includes a polar polymer selected from a polyester, a polylactic acid, and combinations thereof. The second layer is formed from a second composition. The second composition includes at least the following:A) a functionalized ethylene-based polymer; andB) at least one olefin block copolymer.The third layer is formed from a third composition. The third layer includes an olefin-based polymer, a functionalized olefin-based polymer or the salts thereof, a polyester, a polyamide, a polylactic acid, an ethylene vinyl alcohol, and combinations thereof.
