Abstract
"COMPOSIçãO DE FILME SELANTE, ESTRUTURA MULTICAMADAS, FILME, MéTODO PARA PRODUZIR UM FILME E COMPOSIçãO SELáVEL POR CALOR". Esta invenção pertence a uma composição de filme selante compreendendo pelo menos dois materiais de componentes de polímero de etileno. Um aspecto da invenção se relaciona a uma estrutura multicamadas tendo propriedades selantes equilibradas e compreendendo uma camada selante e uma camada de polipropileno, sendo que a camada selante compreende e é feita de uma composição de polímero tendo características de peso molecular particulares e um segundo polímero de etileno. Uma configuração preferida da presente invenção pertence a um filme e composição poliolefínica de densidade média caracterizada por um excelente equilíbrio de uma baixa temperatura de início de selagem e módulo de filme melhorado. O filme e composição são compreendidos de e feitos de pelo menos um polímero de etileno homogeneamente ramificado de densidade mais baixa e pelo menos um polímero de etileno heterogeneamente ou homogeneamente ramificado de densidade mais alta. A invenção é particularmente útil naquelas aplicações requerendo tempos de selagem mais rápidos e boa estabilidade dimensional de embalamento tais como, por exemplo, embalagem para cozimento, embalagem para enchimento a quente, bolsas de material escoável, embalagem de enchimento por compressão, embalagem de filme de encolhimento e embalagem de filme de encolhimento de barreira bem como estruturas de filme de polipropileno biaxialmente orientado (BOPP).
