A polypropylene composition is disclosed, having a sealing initiation temperature below 80 ~C, and containing less than 1% by weight of monomeric units derived from ethylene with respect to the total weight of the composition, and comprising: - from 35 to 68% by weight of a random copolymer of propylene (copolymer (A)) containing 16 to 30% by weight of monomeric units derived from I-butene and from 0 to 0.5% by weight of monomeric units derived from ethylene with respect to the total weight of copolymer (A), and - from 65 to 32% by weight of a random copolymer of propylene (copolymer (B)) containing 35 to 55% by weight of monomeric units derived from I-butene and from 0 to 1% by weight of monomeric units derived from ethylene with respect to the total weight of copolymer (B). Heat-sealable sheets containing a sealing layer of the above composition are also disclosed.

L'invention concerne une composition de polypropylène qui a une température initiale de soudure inférieure à 80 ·C et contient moins de 1 % en poids d'unités monomériques dérivées de l'éthylène, relativement au poids total de la composition, laquelle comprend: - de 35 à 68 % en poids d'un copolymère aléatoire de propylène (copolymère (A)) comportant 16 à 30 % en poids d'unités monomériques dérivées de 1-butène et 0 à 0.5 % en poids d'unités monomériques dérivées de l'éthylène, par rapport au poids total du copolymère (A), et - de 65 à 32 % en poids d'un copolymère aléatoire de propylène (copolymère (B)) comportant 35 à 55 % en poids d'unités monomériques dérivées de 1-butène et 0 à 1 % en poids d'unités monomériques dérivées de l'éthylène, par rapport au poids total du copolymère (B). La présente invention porte également sur des feuilles thermoscellables pourvues d'une couche de soudure de composition susmentionnée.
