Abstract

Una película que tiene primeros y segundos segmentos alternos por la dirección del ancho de la película. Los segundos segmentos son más elásticos que los primeros segmentos, y la fuerza requerida para estirar los segundos segmentos es menor que la requerida para estirar los primeros segmentos. Al menos algunos de los primeros segmentos tienen aberturas a través de su grosor, y el porcentaje del área de los primeros segmentos ocupada por las aberturas es mayor que el porcentaje del área ocupada por las aberturas que puedan extenderse a través de los segundos segmentos. Además, se describen laminados y artículos absorbentes que incluyen tales películas. Se describe, además, un método para fabricar la película.
