Abstract: Provided are oriented films comprising linear low density polyethylene polymer and having improved balance of properties including improved machine direction tear strength. The oriented polymer film has at least one layer comprising 50 to 100 wt. % of an ethylene-based polymer. The MDO polymer film has a normalized MD Elmendorf Tear (ASTM D-1922) of at least 40 g/?m. In certain embodiments, the MDO polymer film surprisingly does not tear when MD Elmendorf Tear is measured according to ASTM D-1922.

Abstract: Provided herein are polyethylene compositions suitable in the fabrication of PE-RT pipes for use in cold and hot water plumbing in accordance with ISO 22391-2, and processes for making the same.

Abstract: Methods for forming polyolefin films using a model including a multivariate adaptive regression splines (MARS)-derived algorithm are provided. Related computing devices are also provided.
