Abstract
Un método para fabricar una estructura de múltiples capas para empaquetar carne con hueso que comprende los pasos de: coextruir una estructura de múltiples capas que comprende al menos una capa sellante que comprende un material que se selecciona del grupo formado por poliolefinas, ionómeros, y mezclas de ellos, una primera capa de poliamida y una capa de barrera; y orientar biaxialmente la estructura de múltiples capas. En dicho método la capa de barrera empleada comprende un copolímero de etileno y alcohol vinílico, y la capa sellante comprende una mezcla de polietileno de baja densidad lineal y polietileno de baja densidad. Dicha primera capa de poliamida comprende una mezcla de poliamida semicristalina y poliamida amorfa. Dicha estructura de múltiples capas tiene entre 1 milipulgada y 8 milipulgadas de espesor, se orienta biaxialmente mediante un método de doble burbuja, a través de un marco tensor.
