  • Publication number: 20240059883
    Abstract: Provided is a polyolefin composition including a) at least one heterophasic polypropylene copolymer with a melt flow rate MFR2 (230° C., 2.16 kg, measured according to ISO 1133) of at least 40 g/10 min, preferably of at least 60 g/10 min ; b) at least one polypropylene homopolymer with a melt flow rate MFR2 (230° C., 2.16 kg, measured according to ISO 1133) of at least 400 g/10 min; and c) a blend (A) of recycled plastic material comprising polypropylene and polyethylene in a ratio between 3:7 and 12:1, which is recovered from a waste plastic material derived from post-consumer and/or post-industrial waste with a melt flow rate MFR2 (230° C., 2.16 kg, measured according to ISO 1133) of at least 5 g/10 min. The polyolefin composition has a melt flow rate MFR2 (230° C., 2.16 kg, measured according to ISO 1133) of at least 20 g/10 min.
