Abstract

Laminado de películas / tramados al azar compatibilizados mecánicamente que -comprende: una capa de película/tramada al azar laminadas entre sí para formar un laminado de película/tramado al azar, dicha capa de película tiene una dirección de máquina y una dirección transversal de máquina, dicha capa tramada al aza tiene una dirección de máquina y una dirección transversal de máquina y dicho laminado tiene una tiene una dirección de máquina y una dirección transversal de máquina, dicha película ha sido orientada en la dirección de máquina antes de ser laminada a la capa tramada al azar, dicha película tiene un espesor máximo de 13 micrómetros o menos; la capa de película luego de la orientación en la dirección de máquina y de la laminación define una elongación al valor de carga pico, dicha elongación de película al valor de rotura en dicha dirección transversal de máquina es mayor que la elongación al valor de carga pico del material tramado al azar en dicha dirección transversal de máquina; dicha capa de película define un valor de carga pico de película, dicha capa tramada al azar define un valor de carga piuco de tramado al azar, y dicho laminado define un valor de carga pico de laminado, siendo dicho valor de carga pico de tramado al azar en la dirección transversal de máquina mayor que el valor de carga pico de película en dicha dirección transversal de máquina y dicho valor de carga pico de película en dirección transversal de máquina y dicho valor de carga pico de película en la dirección transversal de máquina es menor que el valor de carga pico de laminado en la dirección trasversal de máquina, dicho valor de carga pico de laminado en la dirección transversal de máquina es de por lo menos 300 gramos. Como resultado, el laminado es particularmente útil, por ejemplo, como un material de cubierta externa para artículos absorbentes de higiene personal.
