Abstract

"PELìCULA DE MULTICAMADAS, E, MéTODO DE MANUFATURAR UMA PELìCULA TENDO UMA PLURALIDADE DE MICROCAMADAS". Uma película de multicamadas, compreendendo: uma pilha de unidades recorrentes, em que cada unidade recorrente tem pelo menos uma microcamada extrusada de um primeiro material termoplástico e ainda em que o primeiro material termoplástico forma uma barreira contra oxigênio, em que a película tem uma espessura total entre 10 e 2500 <109>m. Se mais do que uma microcamada for contida dentro de cada unidade, então as microcamadas podem ser co-extrusadas juntas. Especificamente, a microcamada de barreira pode ser selecionada dentre EVOH, policetonas, PA6, MXD6, PVDC, LCP, polivinil álcool ("PVOH") ou qualquer outro material de barreira similar contra oxigênio."MULTILAYER FILM, AND, METHOD OF MANUFACTURING A FILM HAVING A MICRO-LAYER PLURALITY". A multilayer film, comprising: a stack of recurring units, in which each recurring unit has at least one microlayer extruded from a first thermoplastic material and yet in which the first thermoplastic material forms an oxygen barrier, in which the film has a thickness total between 10 and 2500 <109> m. If more than one microlayer is contained within each unit, then the microlayers can be co-extruded together. Specifically, the barrier microlayer can be selected from EVOH, polyketones, PA6, MXD6, PVDC, LCP, polyvinyl alcohol ("PVOH") or any other similar oxygen barrier material.
