Abstract

La invención se refiere a un procedimiento para producir una hoja compuesta coextruida y/o laminada y estirada biaxialmente y una hoja multicapa resultante de la misma que tiene una procesabilidad mejorada y/o una reciclabilidad mejorada. Para ello, la invención propone una combinación novedosa de la densidad de los diferentes componentes de las capas de la hoja compuesta y ciertos parámetros de producción como los factores de estiramiento, factores de relajación, temperaturas de relajación y factores de estiramiento residuales.
