Abstract: A polyethylene-based composite film comprising a core layer, a first skin layer and a second skin layer, the core layer being positioned between the first skin layer and the second skin layer, wherein the core layer comprises a polymer blend of a high density polyethylene having a density of 0.940-0.970 g/cc and a melt index of 2-10 g/10 min, and a low density polyethylene having a density of 0.910 0.925 g/cc and a melt index of 0.1-1 g/10 min, wherein the first skin layer comprises greater than 50%, by polymer weight of the first skin layer, of an ethylene-based polymer comprising at least 50 wt. % units derived from ethylene, and wherein the ethylene-based polymer has a density of 0.900 0.920 g/cc and a melt index of 1-10 g/10 min, and wherein the polyethylene-based composite film has an overall density of 0.930-0.950 g/cc.
