Abstract

L'invention se rapporte à des compositions thermoscellables qui servent dans la fabrication de films et de structures de films et qui comprennent: (a) 30 à 70 % en poids d'un polymère à base température de fusion contenant un copolymère à base d'éthylène ayant une densité comprise entre 0,88 g/cm3 et 0,915 g/cm3, un indice de fusion compris entre 1,5 dg/min et 7,5 dg/min, une répartition du poids moléculaire ne dépassant pas 3,5 et un facteur de distribution de la composition supérieure à 70 %; ainsi que (b) 70 à 30 % en poids d'un polymère à base de propylène, différent de (a), contenant un pourcentage molaire de propylène compris entre 88 et 100 et un pourcentage molaire d'une alpha-oléfine autre que le propylène compris entre 12 et 0.
