Abstract:
The present invention relates to a polypropylene composition comprising a propylene homopolymer or a propylene random copolymer having at least one comonomer selected from alpha-olefins with 2 or 4-8 carbon atoms and a comonomer content of not more than 8.0 wt %, wherein the propylene homo- or copolymer is polymerized in the presence of a Ziegler-Natta catalyst, and the polypropylene composition has a MWD of 2.0 to 6.0 and an MFR (2.16 kg/230° C.) of 4.0 g/10 min to 20.0 g/10 min, characterized in that the polypropylene composition has not been subjected to a vis-breaking step, the use of the inventive polypropylene composition for the production of a film and/or injection molded articles, a process for preparing a film wherein the inventive polypropylene composition is formed into a film, and wherein the polypropylene composition has not been subjected to a vis-breaking step and a film comprising the inventive polypropylene composition.
