La invención se refiere a un proceso para el estiramiento de una banda de película de partida de material de polímero termoplástico, que contiene al menos un componente de polímero de bajo punto de fusión y al menos un componente de polímero de alto punto de fusión, comprendiendo el las siguientes etapas: calentamiento de la banda de película de partida hasta el estado parcialmente fundido, en el que se encuentra el al menos un componente de polímero de bajo punto de fusión en el estado fundido y el al menos un componente de polímero de alto punto de fusión en estado no fundido, mediante al menos un rodillo de calentamiento, y enfriamiento mediante conducción de la banda de película parcialmente fundida por una ranura de rodillo enfriada, estirándose la banda de película entre el al menos un rodillo de calentamiento y la ranura de rodillo enfriada. Las películas producidas pueden ser laminadas con una tela no tejida.
