    摘要: The present invention relates to a polypropylene composition comprising a first component being a propylene polymer produced in presence of a metallocene-based catalyst system, and a second component being a random copolymer of propylene and one or more comonomers, said random copolymer being produced in presence of a Ziegler-Natta polymerization catalyst. The polypropylene composition of the present invention is particularly suited for blown film and is characterized by excellent optical properties. Further, the present invention relates to a multilayer film or a laminate comprising such a blown film. Additionally, the present invention relates to a process for producing such a blown film, multilayer film or laminate.
