Abstract
"FILME MULTI-CAMADAS SELáVEL A QUENTE, BOLSA E PROCESSO PARA A FABRICAçãO DE BOLSAS". A presente invenção refere-se à utilização de um filme multi-camadas selável a quente para a fabricação de bolsas para conter materiais fluidos, que se apresentam em forma tubular e possuem extremidades seladas transversalmente a quente, com o mencionado filme compreendendo pelo menos uma camada compreendendo cerca de 10% em volume da estrutura geral do filme, sendo fabricado a partir de um copolímero de etileno-estireno obtido pela utilização de um processo de polimerização de catalisador de sítio único e uma ou mais das seguintes camadas: (a) pelo menos um interpolímero selecionado a partir de interpolímeros de etileno e uma ou mais <244>-olefinas C~ 3~-C~ 20~ fabricadas através de processos de polimerização utilizando catalisador de sítio único, catalisador que não seja de sítio único e misturas de tais catalisadores, bem como suas ligas, possuindo os mencionados interpolímeros densidade na faixa de cerca de 0,87 a 0,940 g/cc e um índice de fusão de cerca de 0,2 a 20 dg/minuto, compreendendo cerca de 10 a 90% em volume da estrutura total do filme; (b) pelo menos uma camada de barreira selecionada a partir de polímeros de nylon compreendendo cerca de 5 a 30% em volume da estrutura total do filme; polímeros de tereftalato de polietileno compreendendo cerca de 5 a 15% em volume da estrutura total do filme; nylon amorfo compreendendo cerca de 5 a 30% em volume da estrutura total; álcool vinil etileno compreendendo cerca de 5 a 25% em volume da estrutura total do filme; (c) pelo menos uma camada compreendendo cerca de 5 a 15% em volume da estrutura total do filme e selecionada a partir de polímero etileno vinil acetato, copolímeros de ácido etileno, ionómeros ou copolímeros de etileno funcionalizados por anidrido; e (d) pelo menos um homopolímero de etileno de alta pressão.
