Abstract

Se proveen, una película de polipropileno orientada biaxialmente (PPOB) con propiedades mejoradas de barrera, y un método para formar la película. El RTVH de una película de PPOB de capas multiples, se mejora mezclando cera en la resina de capa de matriz, y proveyendo una capa de cubierta de poliolefina sobre cada lado de la capa de matriz. Se observan mejoras adicionales significativas, cuando la película se calienta a una temperatura por debajo del punto de fusion de la resina de capa de matriz, por debajo de la temperatura de distorsion de la película, y por arriba del punto de fusion de la cera durante una longitud de tiempo que se extiende, generalmente de por lo menos cinco minutos a varias horas, dependiendo de la temperatura.
