Abstract: The present technology relates to container comprising a propylene, ethylene, 1-butene terpolymer wherein in the terpolymer: i) the content of ethylene derived units ranges from 0.5 wt % to 1.8 wt %; ii) the content of 1-butene derived units ranges from 3.5 wt % to 6.5 wt %; iii) the ratio C2 wt %/C4 wt % ranges from 0.12 to 0.22; wherein C2 wt % is the weight percentage of ethylene derived units, and C4 wt % is the weight percentage of 1-butene derived units; iv) the total content of ethylene and 1-butene derived units is comprised between 4.2 wt % and 7.5 wt %; v) the melt flow rate (MFR measured according to ISO 1133, 230° C., 2.16 kg) ranges from 20 to 80 g/10 min; vi) the xylene soluble fraction at 25° C. is lower than 7.0 wt %; and vii) the melting point is higher than 140° C.
