Abstract

"PELìCULA DESTACáVEL DE POLIPROPILENO IMPERMEáVEL AOS GASES". A invenção presente refere-se a uma película de poliolefina em multicamadas co-extrudada sendo vedável a quente e destacável sobre substratos baseados em polipropileno de pelo menos 3 camadas, compreendendo pelo menos uma camada de topo destacável, pelo menos uma camada intermediária e pelo menos uma camada-base, caracterizada pelo fato de pelo menos uma das camadas intermediárias compreender um polímero de baixa fusão capaz de fluir facilmente com um índice de fluxo de fusão pelo menos igual ou maior que o índice de fluxo de fusão da camada-base, o dito polímero capaz de fluir facilmente representando pelo menos 60% em peso do peso total da dita película polimérica em multicamadas.
