Abstract
Un procedimiento para obtener una película termoplástica laminar, susceptible de ser fijada o soldada térmicamente, cuyo procedimiento comprende las operaciones de: (a) producir una capa debase de polipropileno y (b) unir un lado de la capa de polipropileno con un copolimero que tiene un punto de fusión mas bajo que el de la películas de polipropileno, siendo el copolimero un copolimero a base de polietileno que comprende un copolimero lineal de baja densidad de etileno y una alfa-olefinas que tiene de 3 a 10 átomos de carbono.
