Abstract
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.
