Abstract

PELÍCULA DE BARREIRA DE EVOH COM CHOQUE EM AUTOCLAVE REDUZIDO. A presente invenção refere-se a uma película de barreira (10) que mantém uma barreira de oxigênio depois de ser submetida a condições de esterilização em autoclave. A película compreende uma camada de EVOH (18) posicionada como uma camada de núcleo, e uma camada de EVOH (14) posicionada diretamente adjacente a uma camada externa (12) compreendendo material altamente permeável tendo uma permeabilidade do vapor de umidade maior do que cerca de 1,016 g-mm/65,35 cm2-dia-MPa (40 g-mil/100 polegada2-dia-atm). Durante esterilização em autoclave, as propriedades de barreira da camada de EVOH (12) posicionada adjacente à camada externa (12) possibilita aprimorada recuperação de propriedades de barreira de oxigênio. Além disso, durante aplicações de reumedecimento, a camada interna de EVOH (18) mantém a barreira de oxigênio. Também são descritos métodos para produzir e usar a película de barreira descrita (10).
