This invention relates to fabricated articles, including films or sheets prepared from blends of substantially random ethylene/propylene/vinyl aromatic monomer interpolymers with propylene homopolymers or copolymers. The fabricated articles exhibit high toughness, tensile properties and heat resistance and low stress whitening, and further can exhibit desirable optical properties, especially when in the form of a film or sheet.
