Abstract: The present disclosure provides an article of manufacture made from or containing a propylene-based terpolymer, having (i) ethylene-derived units in the range from about 0.5 wt. % to about 1.8 wt. %; (ii) 1-butene-derived units in the range from about 1.5 wt. % to about 2.5 wt. %; (iii) a ratio of C2 wt %/C4 wt % in the range from about 0.40 to about 0.80, wherein C2 wt % is the weight percent of ethylene-derived units and C4 wt % is the weight percent of 1-butene-derived units; (iv) a melt flow rate in the range from about 30 g/10 min to about 80 g/10 min; (v) a xylene soluble fraction at 25° C. lower than about 5.0 wt. %; and (vi) a melting point higher than about 140° C. The article can be a container, which can be used for food applications.
