Abstract

resumo “filme com faixas e mechas alternadas e aparelho e método para a produção do mesmo” a presente invenção refere-se a um filme que compreende faixas alternadas com mechas. em algumas modalidades, as mechas têm um núcleo e uma bainha. o núcleo é mais elástico que a bainha e que as mechas. em algumas modalidades, o filme tem um alongamento de ao menos 75 por cento, a largura das mechas situa-se em uma faixa de 100 micrômetros a 750 micrômetros, e uma porção de cada mecha forma parte de ao menos uma superfície principal do filme. uma matriz de extrusão útil para produzir o filme e um método para produzir o filme com o uso da matriz de extrusão também são apresentados.
BR112015007535-5A 2012-10-02 2013-10-02 filme com faixas e mechas alternadas, laminado, artigo absorvente, matriz de extrusão e método de fabricação do referido filme BR112015007535B1 (pt)
