Abstract: Provided herein are monolayer films, and also multilayer films comprising a core, a subskin disposed on the core, and a skin disposed on the subskin. The films may have an Elmendorf tear in MD greater than about 7.0 g/μm, a dart impact greater than about 6.0 g/μm, and a 1% secant modulus greater than about 200 MPa. In multilayer films, the core comprises a first polyethylene blend comprising an ethylene 1-hexene copolymer and a high density polyethylene composition in an amount between about 0 wt. % and about 40 wt. %. Further provided herein are bags and laminates comprising the present films.
