Patent ID: 7217767

Claim:
A film or sheet material comprising a blend of: at least one broad molecular weight distribution ethelene/propylene rubber impact-modified heterophasic copolymer (ICP), wherein the ICP has a polydispersity from about 4 to about 12, a melt flow rate from about 0.5 to about 5.0 dg/min and xylene solubles of about 25% or less; and from about 5 to about 95 wt % of at least one second polyolefin, where the second polyolefin is selected from the group consisting of a syndiotactic polypropylene (sPP), a medium density polyethylene (MDPE), a linear low density polyethylene (LLDPE), a low crystalline copolymer of propylene/α-olefin, and a random copolymer (RCP) of propylene and comonomer selected from the group consisting of ethylene and butenes, where the RCP is made using a Ziegler-Natta catalyst (ZNRCP) or a metallocene catalyst (mRCP).
