Title: Polymeric films

Abstract: Polypropylene films having a base layer of a propylene polymer with at least one matte outer layer of a blend of a polyether block polyamide, polypropylene, and polybutene-1, the polybutene-1 representing from 40 to 60 wt. % of the blend. Such films have shown good antistatic properties combined with particularly low heat seal thresholds compared with similar films without the polybutene-1 in the outer layer or layers.
