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.

Films made of polyethylene blends for improved bending stiffness and high MD tear resistance

The present disclosure provides polyolefin compositions and films and method for producing such films. The polyolefin composition contains about 40 wt % to about 95 wt % of a BOCD polyethylene and about 10 wt % to about 60 wt % of a polypropylene, by weight of the polyolefin composition. The polyolefin composition has a 1% secant flexural modulus MD of greater than 250 MPa and a 1% secant flexural modulus TD of greater than 300 MPa, as determined for a layer of the polyolefin composition having a thickness of about 50 μm and a Dart Impact (Method A) of greater than 15 g/μm and an Elmendorf tear MD of greater than 7 g/μm, as determined for a film containing the polyolefin composition and having a thickness of about 90 μm.

Polyolefin compositions suitable for films

Disclosed are multilayer films which can provide desired film performance suited for packaging applications favoring cost-effectiveness.
