1. A polymer composition comprising:
(A) from 85 to 96 wt % of a multimodal propylene random copolymer;
(B) from 4.0 to 6.0 wt % of a multimodal copolymer of ethylene with one or more comonomer units selected from alpha-olefins having from 4 to 8 carbon atoms;
(C) from 150 to 750 ppm of a terpolymer of vinylidene fluoride, tetrafluoroethylene, and hexafluoropropylene;
(D) from 250 to 1000 ppm of 1,3:2,4-bis(3,4-dimethylbenzylidene) sorbitol (DMDBS); and
(E) from 130 to 300 ppm of polyethylene glycol,
wherein all weight amounts are based on the total weight amount of the polymer composition.
