CA 2315069

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.

L'invention concerne des films en polypropylène ayant une couche de base en polypropylène dotée d'au moins une couche extérieure mate dont le matériau est un mélange de polyamide bloc de polyéther, de polypropylène et de polybutène-1, ce dernier élément représentant entre 40 et 60 % du mélange, en poids. Les films polymères considérés ont de bonnes propriétés antistatiques combinées à des seuils de thermoscellage particulièrement faibles, par rapport à des films analogues dont la ou les couches extérieures sont dépourvues de polybutène-1.
