摘要：
A 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 C2wt%/C4wt% ranges from 0.12 to 0.22; wherein C2wt% is the weight per cent of ethylene derived units and C4wt% is the weight per cent 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%; vii) the melting point is higher than 140°C.
