Abstract

La invención está en un campo de películas de paredes relativamente gruesas de barrera contra la humedad y los gases y se refiere a una película de barrera coextruida y termoestable plana adecuada para usar en la industria alimentaria y el método para la fabricación de la misma. La película comprende una capa exterior termosellable hecha principalmente de una (co)poliolefina con una temperatura de ablandamiento Vicat que no excede los 130 °C, al menos una capa resistente al calor hecha principalmente de al menos un (co)polímero polar seleccionado del grupo que incluye predominantemente (co)poliamidas alifáticas y (??)poliésteres aromáticos, al menos una capa adhesiva núcleo de un material capaz de adherirse tanto a (??)poliolefinas como a (??)polímeros polares, en donde dicha capa resistente al calor hecha de (co)poliamidas predominantemente alifáticas comprende no menos del 15 % de al menos una copoliamida predominantemente alifática con una temperatura de fusión que no excede los 205 °C. El método comprende las etapas de coextrusión, estiramiento biaxial, termoendurecimiento y embobinado de la película resultante en un rollo, de manera que la relación de estiramiento de la superficie a estiramiento biaxial no es inferior a 8, y la etapa de termoendurecimiento se acompaña de relajación y contracción lineal en al menos una de las direcciones de la máquina y transversal en más del 25 %, y mediante relajación y contracción superficial en más del 40 %. La invención proporciona la película que puede usarse para termoformado mediante el método de estiramiento profundo en condiciones severas y los productos formados poseen la seguridad mecánica conveniente. Dos reivindicaciones independientes y 13 dependientes, 2 figuras, 3 tablas y 7 ejemplos.
