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