Abstract

Esta invención describe una película de capas múltiples para hacer bolsas para contener materiales líquidos, la película de capas múltiples comprende generalmente cinco capas en orden: capa selladora interior, primera capa interpuesta, la capa central, segunda capa interpuesta y la capa selladora exterior. Las capas selladoras y central son a base de etileno, y las capas interpuestas son a base de polipropileno. El espesor de la película de capas múltiples está en el intervalo de aproximadamente 35 micras a alrededor de 66 micras. Las capas interpuestas comprenden una novedosa mezcla de polipropileno con un componente principal de polipropileno y un componente menor de polipropileno, en donde el componente de polipropileno menor es un interpolímero de polipropileno heterogéneo con una densidad en el intervalo de aproximadamente 0.875 a alrededor de 0.91 g/cm3.
