<p>Polypropylene films having a base layer of a propylene polymer with at least one matt 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.</p> |
