Abstract

PELÍCULA NANOCOMPOSTA RÍGIDA PARA USO EM UM ARTIGO ABSORVENTE. É fornecida uma película nanocomposta fina para uso em um artigo absorvente (por exemplo, absorvente feminino). A película contém um primeiro polímero de etileno com uma densidade de cerca de 0,94 g/cm 3 ou menos, um segundo polímero de etileno com uma densidade maior que 0,94 g/cm 3, e uma nanoargila com um tratamento orgânico de superfície. Os presente inventores descobriram que através do controle seletivo do tipo e concentração específicos dos componentes usados para formar a película, bem como a forma na qual ela é formada, as propriedades da película podem ser significativamente melhoradas.
