Abstract

resumo “película de múltiplas camadas” a película de múltiplas camadas compreende: uma primeira camada externa que é vedável por aquecimento. a primeira camada externa compreendendo de 95 a 100 por cento (em peso da primeira camada externa) de um primeiro polímero, dito primeiro polímero sendo derivado de monômero de propileno e, opcionalmente, um ou mais comonômeros selecionados a partir do grupo consistindo de etileno e alfa-olefinas c4-c8. o primeiro polímero tendo um ponto de fusão de pelo menos 125°c. a película de múltiplas camadas compreende ainda uma porção interna adjacente para a primeira camada externa. a porção interna pode ser uma camada única ou pode compreender várias camadas. pelo menos uma camada da porção interna compreende um polímero à base de propileno elastomérico (“epbp”). ademais, pelo menos uma camada da porção interna compreende um segundo polímero, onde o segundo polímero é selecionado a partir do grupo consistindo de polietileno de baixa densidade e alta pressão, polietileno de alta densidade, copolímeros de ácido acrílico etileno, copolímeros de ácido (met)acrílico de etileno e combinações dos mesmos. o segundo polímero pode estar junto com epbp na mesma camada ou pode ser em uma camada separada. deve também ser contemplado que a porção interna pode, opcionalmente, compreender uma ou mais camadas adicionais; as quais podem ou não podem conter epbp ou o segundo polímero. a película de múltiplas camadas compreende, ainda, uma segunda camada externa arranjada de modo que a porção interna seja encapsulada entre a primeira camada externa e a segunda camada externa. a segunda camada externa compreende um terceiro polímero, onde o referido terceiro polímero é selecionado a partir do grupo consistindo de polipropileno homopolimérico, polipropileno copolimérico aleatório e polipropileno de copolímero de impacto e misturas dos mesmos. 2/1
