Abstract: The present invention is a polyolefin composition, which comprises a thermoplastic olefin polymer and a polyethylene. The thermoplastic olefin polymer (TPO) comprises a polypropylene and an olefin copolymer and is present in an amount of about 10 weight percent to about 50 weight percent; the TPO has a density in the range of about 0.85 g/cm3 to about 0.92 g/cm3 and a flexural modulus of less than about 700 MPa as measured by ISO 178. The polyethylene is either a medium density polyethylene or a high density polyethylene and present in an amount of about 50 weight percent to about 90 weight percent. The polyolefin composition is useful for preparing articles of manufacture such as sheets, roofing membranes, geomembranes, soft skins, drawn tapes, drawn fibers, and drawn filaments.
