Abstract

composiçao adequada para uso em uma película soprada resfriada bruscamente ao ar e pelicula soprada resfriada bruscamente ao ar. a invenção é direcionada a uma composição adequada para películas sopradas resfriadas bruscamente ao ar de alto brilho. as películas são compreendidas de 2 a 15% em peso de um copolímero baseado em propileno substancialmente isotático tendo uma taxa de fluxo de fundido de pelo menos 5 g/10 min e tendo de 8 a 21 moles por cento de unidades derivadas de uma alfa-olefina, e de 85 a 98% em peso de um copolímero baseado em etileno tendo um índice de fusão de 0,1 a 9 g/10mm. uma película soprada resfriada bruscamente ao ar feita da composição inventiva exibe um valor de brilho maior que um valor de brilho exibido por uma película soprada resfriada bruscamente ao ar feita apenas com o copolímero baseado em etileno.
