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/&#x3bc;m. In certain embodiments, the MDO polymer film surprisingly does not tear when MD Elmendorf Tear is measured according to ASTM D-1922.

Oriented films comprising ethlyene-based polymers and methods of making same

Polyethylene compositions described herein have a density from about 0.900 g/cmto about 0.950 g/cm, a MI (I, 190&#xb0; C., 2.16 kg) from about 0.1 g/10 min to about 10 g/10 min, an MIR (I/I) from about 25 to about 80, an Mgreater than or equal to about 150,000 g/mol, and either an M/Mratio greater than or equal to about 8.0, an M/Mratio greater than or equal to about 2.4, or an (I*M/M) from about 3 to about 100. The polyethylene compositions are useful in wire and cable, tape, and filament applications, and could be produced using a gas phase or slurry phase, preferably gas phase, polymerization process.

Polyethylene compositions, wire and cables, and methods for making the same

A bimodal polyethylene is provided. The bimodal polyethylene may include a high molecular weight portion having a weight average molecular weight (M) of 100,000 g/mol to 1,000,000 g/mol and a low molecular weight portion having a Mof 10,000 g/mol to 80,000 g/mol. Polymer extrudates, such as cable-coatings and/or wire-coatings and films, including the bimodal polyethylene as well as methods of making the polymer extrudates are also provided.

Polyethylene extrudates and methods of making the same

Sheets made from metallocene-catalyzed polyethylene polymers, optionally, with other polymers, are disclosed.
