Abstract
The present invention relates to a heterophasic polypropylene composition with rather high melt flow rate, high stiffness, acceptable impact properties and an advantageous balance between stiffness and transparency. Still further, the present invention is also directed to a process for producing the inventive polypropylene composition, to an article made of the inventive polypropylene composition and to the use of the inventive polypropylene composition for the production of films and molded articles, such as thin-walled plastic containers for packaging. The inventive heterophasic polypropylene composition comprises at least a propylene homopolymer fraction, a propylene random copolymer fraction, two different ethylene-propylene rubber fractions and an ethylene homo- or copolymer fraction.
