Abstract

L'invention est relative à un film soudable à chaud en polypropylène comprenant un fil de base biaxialement orienté renfermant au moins 50 % d'unités de polypropylène, ce film de base étant muni sur au moins une surface, par laminage, d'une couche soudable à chaud, caractérisé en ce que la ou les couches soudables à chaud sont constituées d'un mélange de polymères comprenant une proportion comprise entre 20 et 80 % en poids de polybutène-1 tactique et une proportion comprise entre 80 et 20 % en poids de polypropylene isotactique.The invention relates to a heat-sealable polypropylene film comprising a biaxially oriented base wire containing at least 50% of polypropylene units, this base film being provided on at least one surface, by lamination, with a layer heat-weldable, characterized in that the heat-weldable layer or layers consist of a mixture of polymers comprising a proportion of between 20 and 80% by weight of tactical polybutene-1 and a proportion of between 80 and 20% by weight of isotactic polypropylene.
