摘要： 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/μm. In certain embodiments, the MDO polymer film surprisingly does not tear when MD Elmendorf Tear is measured according to ASTM D-1922.
