Abstract

La presente invencion se refiere a una película polimérica de capas multiples que comprende una capa base de un polímero de propileno, una capa intermedia sin huecos o vacíos sobre la capa base, y una capa polimérica termosellable sobre la capa intermedia, la capa intermedia sin huecos o vacíos tiene una fuerza cohesiva interna menor que la fuerza de union de la capa intermedia a ya se ala capa base o la capa termosellable y menor que las fuerzas cohesivas internas ya sea de la capa base o de la capa termosellable. Tales películas hacen posible que los sellos térmicos desprendibles sean formados por la ruptura de al capa intermedia debido a su fuerza cohesiva interna inferior comparada con la de la capa del nucleo o la de la capa termosellable.
