Polyolefin-based containers
A container comprising a polyolefin composition comprising: A) from 59 wt. % to 84 wt. %, based upon the total weight of the polyolefin composition, of a propylene homopolymer having isotactic pentads (mmmm) measured with 13 C-NMR higher than 96%, B) from 16 wt. % to 41 wt. %, based upon the total weight of the polyolefin composition, of a copolymer of propylene and ethylene, wherein the copolymer of propylene and ethylene comprises from 30 wt. % to 44 wt. %, of ethylene derived units based upon total weight of the copolymer of propylene and ethylene; the sum A)+B) being 100 wt. %; the polyolefin composition having an MFR L (Melt Flow Rate according to ISO 1133, condition L, i.e. 230° C. and 2.16 kg load) between 72 and 100 g/10 min.
