An oriented, i.e. uniaxial or biaxial, thermoplastic article, e.g. extruded sheet, blown film, and cast film, comprising a first component comprising a continuous phase and a dispersed phase, where A) the continuous phase contains a polymer composition resulting from the polymerization of a monomer mixture containing a styrenic monomer and an alkyl (meth)acrylate monomer in the presence of the dispersed phase; and B) the dispersed phase contains one or more block copolymer selected from diblock and triblock copolymers of styrene-butadiene, styrene-butadiene-styrene, styrene-isoprene, styrene-isoprene-styrene, partially hydrogenated styrene-isoprene-styrene, wherein the oriented thermoplastic article has a thickness ranging from 0.02 mm to 0.50 mm, a tensile strength ranging from 15 Mpa to 70 Mpa as measured by ASTM D 882, an impact value ranging between 0.05 ft. lb/mil to 1.0 ft. lb/mil as measured by ASTM D 3763, and a Haze value less than 10% as measured by ASTM D 1003.
