Provided is a polyolefin composition including 20-65 wt % of at least one high density polyethylene including at least one polyethylene homopolymer and at least one polyethylene copolymer with a melt flow rate MFR5 (190° C., 5 kg, measured according to ISO 1133) of at least 0.8 g/10 min and a B10 ESCR above 600 hours (measured according to ASTM D1693); 35-80 wt % of a polyethylene enriched blend of recycled plastic material, with a C2 fraction in amount of above 96.5 wt. %, as measured by NMR of the d2-tetrachloroethylene soluble fraction, and a continuous C3 fraction in amount of ≤3.5 wt.-%, as measured by NMR of the d2-tetrachloroethylene soluble fraction; optionally further additives, wherein the sum of all ingredients always adds up to 100 wt %. The polyolefin composition has an impact strength (ISO179-1, Charpy 1eA+23° C.) of at least 25 kJ/m2.
