It has been discovered that the properties of sheet or film materials of broad molecular weight distribution ethylene/propylene rubber impact-modified heterophasic copolymer (ICP) can be improved by blending the ICP with a second polyolefin. The second polyolefin may be a syndiotactic polypropylene (sPP), a random copolymer (RCP) of propylene and comonomer (e.g. ethylene and/or butene) made using a Ziegler-Natta or metallocene catalyst, medium density polyethylene (MDPE), linear low density polyethylene (LLDPE), or low crystalline copolymer of propylene/&#x3b1;-olefin. Improvements include, but are not necessarily limited to, reduced motor amps, lower secant modulus, increased dart drop strength, increased gloss, reduced haze, increased elongation to yield, elimination of stress whitening, improved puncture resistance, and decreased seal initiation temperature. This sheet of film materials may be co-extruded with other resins or laminated with other materials after extrusion.

Articles of manufacture and a method of making the articles are provided. The articles of manufacture comprise CpFlu metallocene catalyzed polypropylene homopolymers and C&#x2013;Crandom copolymers having narrow molecular weight distributions and low xylene solubles (or extractables) contents. Because of a number of desirable properties, the polypropylene homopolymers and C&#x2013;Crandom copolymers may be used to prepare a wide variety of useful articles, including but not limited to cast films, such as packaging; fibers suitable for use in fabrics and carpet applications, and injection and blow molded items such as bottles.
