Abstract
Se refiere a una estructura de película de barrera encapsulada y un método para preparar la misma y más específicamente, a una película multicapa termoplástica de empaque que tiene una capa de barrera formada por un material polimérico termalmente sensible, preferentemente alcohol vinílico de etileno. Una ventaja de la presente es la de ofrecer una estructura de película y un método para realizarla que utilice un material de barrera relativamente barato para prevenir la migracion de gases a través de la estructura de película. Una estructura de película que comprende: una capa barrera termalmente sensible, hecha de un primer material polimérico que tiene una temperatura de fundicion que oscila entre los 189 y 212 degree C; un primer conjunto de capas adhesivas dispuestas en superficies opuestas de la capa barrera donde las primeras capas adhesivas están hechas de un segundo material polimérico que tiene una temperatura de fundicion de entre 189 a 212 degree C; un segundo conjunto de capas adhesivas sobre una superficie exterior de las primeras capas adhesivas que tienen una temperatura de fusion de entre 274 a 293 degree C. Dicha estructura donde la capa barrera está hecha de un material que comprende alcohol vinílico de etileno. Dicha estructura donde la capa barrera está hecha de un material que se selecciona del grupo consistente de copolímero de alcohol vinílico de etileno, combinado con polietileno; poliamida; acrilonitrilo y copolímero de cloruro de polivinilideno. Dicha estructura que comprende además: una capa selladora que forma una capa exterior de la estructura de película dispuesta en forma adyacente a una superficie exterior de las segundas capas adhesivas; y una capa exterior de la estructura de película dispuesta en un lado opuesto de la estructura de película en relacion con la capa selladora. Un método de preparacion de dicha estructura de película que comprende los pasos de: provision de un primer extrudado para extrudar un material de barrera termalmente sensible; provision de un segundo extrudado para extrudar un primer material adhesivo; encapsulacion del material de barrera mediante el primer material adhesivo en un primer encapsulador para formar un primer extrudado a una primera temperatura; provision de un segundo material adhesivo; extrusion del segundo material adhesivo a través de un tercer extrusor; adhesion del primer extrudado al segundo adhesivo a una temperatura para formar una masa fundida combinada en la cual la segunda temperatura es superior a la primera temperatura; y alimentacion de la masa fundida combinada a través de una matriz para formar una hoja delgada que incluye una capa barrera encapsulada por primeras capas adhesivas en lados opuestos de la capa barrera y en donde además al menos una de las primeras capas adhesivas están unidas a una segunda capa adhesiva en una superficie exterior de las primeras capas adhesivas.
