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, mientras que 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. El espesor combinado de las primera y segunda capas interpuestas está en el intervalo de aproximadamente 10% a alrededor de 27% del espesor total de la película de capas múltiples. De manera similar, un espesor combinado de las capas selladoras interior y exterior está en el intervalo de aproximadamente 10% a alrededor de 27% del espesor total de la película de capas múltiples. Las capas interpuestas comprenden polipropileno que tiene un índice de fusión de menos de 0.75 dg/mm.
