Abstract

Patente de Invenção: "PELìCULA PARA EMBALAGEM DE MúLTIPLAS CAMADAS, CO-EXTRUDADA FEITA DE MATERIAIS DE POLìMERO DE PROPILENO". Uma película de múltiplas camadas co-extrusada para a embalagem de produtos recentemente cortados consiste em (1) uma camada externa de um terpolímero de etileno/propileno/alfa-olefina 4-8 C, (2) uma camada intermediária contendo pelo menos um de (a) 0-100% do terpolímero descrito em (1) e (b) 0-100% de uma mistura de (i) aproximadamente 99,5% a aproximadamente 95% de uma composição de copolímero de olefina feita por polimerização seq³encial em pelo menos dois estágios e (ii) aproximadamente 0,5% a aproximadamente 5% de um polietileno de baixa densidade, onde (a) + (b) = 100% e (3) uma camada interna contendo pelo menos um de (a) 0-100% de um copolímero de etileno e uma alfa-olefina C~ 4~-C~ 8~ feita usando um catalisador de metaloceno e tendo uma densidade de 0,89 a 0,91 g/cm^ 3^ e (b) 0-100% da mistura (b) descrita na camada (2), onde (a) + (b) = 100%. As razões de espessura das camadas e, quando ambos os componentes estão presentes, a quantidade de cada polímero nas misturas das camadas (2) e (3) podem ser variadas para igualar a taxa de transmissão do gás do produto a ser embalado.
