Patent ID: 7413812

Claim:
A polypropylene article comprising a layer of substantially syndiotactic polypropylene having a melting point of from about 125° C. to 135° C. and comprising a polypropylene homopolymer or a copolymer of propylene and an olefin monomer of from 2 to 10 carbon atoms, and at least one layer of substantially isotactic polypropylene comprising a polypropylene homopolymer or a copolymer of propylene and an olefin monomer of from 2 to 10 carbon atoms joined to the layer of syndiotactic polypropylene layer so that the layers form a sheet having a haze at a thickness of 20 mils of from 4.6% to 6.2% and a notched Izod of from greater than 1.1 ft-lb/in. to less than 13.3 ft-lb/in, and wherein at least one of the layers is non-oriented.
