Abstract

La presente divulgación se dirige a proporcionar una película multicapa para usarse en una bolsa de aire, la cual proporciona suficiente adhesividad y tendencia a bloqueo en una manera bien equilibrada. La película multicapa para usarse en una bolsa de aire de acuerdo con la presente divulgación incluye una capa adhesiva y una capa externa. La capa adhesiva incluye una resina que tiene una temperatura de transición vítrea desde 0 °C hasta 80 °C y un punto de fusión desde 100 °C hasta 160 °C. La capa externa incluye una resina que tiene un punto de fusión mayor que el punto de fusión de la resina incluida en la capa adhesiva por 20 °C o mayor. Además, una bolsa de aire de acuerdo con la presente divulgación incluye una tela de fibra sintética y la película multicapa antes mencionada para usarse en una bolsa de aire, en la cual la capa adhesiva en película multicapa se lamina con la tela de fibra sintética.
