Abstract

Se proveen métodos para producir películas de polietileno que tienen un régimen de transmision de vapor de agua (WVTR) deseado. Los métodos incluyenmoldear una lámina de polietileno que tiene una capa de base de un polietileno y un agente de cavitacion, y por lo menos una capa de un material de control deWVTR, y seguidamente orientar biaxialmente la lámina para producir una película que tiene el WVTR deseado. La capa de base tiene una microestructura porosa yun WVTR sustancialmente más elevado que el WVTR deseado.
