Disclosed is a propylene polymer composition consisting essentially of (A) a propylene polymer resin and (B) from 0.05 to 0.2 parts of a normally solid, high molecular weight, gel-free, propylene polymer material having (1) a branching index of less than 1 and significant strain hardening elongational viscosity, or (2) at least (a) either z-average molecular weight M.sub.z of at least 1.0.times.10.sup.6 or a ratio of the z-average molecular weight M.sub.z to weight average molecular weight M.sub.w, M.sub.z /M.sub.w, of at least 3.0 and (b) either equilibrium compliance J.sub.eo of at least 12.times.10.sup.-5 cm.sup.2 /dyne or recoverable shear strain per unit stress Sr/S of at least 5.times.10.sup.-5 cm.sup.2 /dyne at 1 sec.sup.-1.
