Abstract: A polymer composition includes: (a) a propylene-based polymer having a melt mass-flow rate of ≥5.0 and ≤90.0 g/10 min; and (b) ≥5.0 and ≤30.0 wt %, with regard to the total weight of the polymer composition, of an ethylene-based polymer having: a melt mass-flow rate of 3.0 and ≤30.0 g/10 min; a density of ≥840 and ≤870 kg/m3; and a content of ≥25.0 and ≤50.0 wt % of moieties derived from 1-octene, with regard to the total weight of the ethylene-based polymer. Such polymer composition demonstrates improved low temperature impact strength, determined as Izod impact strength at −40° C. and/or at −30° C., as well as desirable toughness, determined as tensile modulus, whilst having good flowability in injection moulding and thereby allowing complex, thin-walled objects to be shaped.
