Abstract

La película de capas múltiples comprende una primera capa externa termosellable. La primera capa externa comprende desde 95 hasta 100 por ciento (en peso de la primera capa externa) de un primer polímero, siendo derivado del primer polímero de monómero de propileno y opcionalmente uno o más, comonómeros seleccionado del grupo que consiste en etileno y C4-C8 alfa olefinas. El primer polímero debe tener un punto de fusión de al menos 125°C. La película de capa múltiple comprende además una parte interna adyacente a la primera capa externa. La parte interna puede ser una capa simple o puede comprender varias capas. Al menos una capa de la parte interna comprende un polímero a base de propileno elastómerico ("EPBP"). Además, al menos una capa de la parte interna comprende un segundo polímero, en donde el segundo polímero se selecciona del grupo que consiste en polietileno de baja densidad de alta presión, polietileno de alta densidad, copolímeros de ácido acrílico de etileno, copolímeros de ácido (met) acrílico de etileno y combinaciones de los mismos. El segundo polímero puede estar junto con el EPBP en la misma capa o puede estar en una capa separada. También se contempla que la parte interna pueda comprender opcionalmente una o más capas adicionales, lo cual pueda no contener EPBP o el segundo polímero. La película de capa múltiple comprende además una segunda capa externa distribuida de modo que la parte interna esté encapsulada entre la primera capa externa y la segunda capa externa. La segunda capa externa comprende un tercer polímero, en donde el tercer polímero se selecciona del grupo que consiste en homopolímero de polipropileno, copolímero de polipropileno aleatorio y copolímero de polipropileno de impacto y combinaciones de los mismos.
