Abstract

filmes adequados para aplicações de filme retrátil são divulgados compreendendo pelo menos um interpolímero de etileno heterogêneo com um índice de perfil de distribuição de ramificação de cadeia curta, dpiscb, que satisfaz a fórmula (i) -1 = dpiscb = 1. o pelo menos um interpolímero de etileno heterogêneo tem uma densidade de cerca de 0,911 g/cm3 a cerca de 0,942 g/cm3, um índice de fusão de cerca de 0,2 dg/min a cerca de 3,5 dg/min e é produzido usando um catalisador ziegler-natta em linha. modalidades adicionais incluem filmes retráteis preparados a partir de misturas de pelo menos um interpolímero de etileno heterogêneo e pelo menos um polímero etileno de alta pressão. os filmes retráteis divulgados têm resistência à perfuração melhorada e força de retração do túnel de retração da direção da máquina em relação aos filmes retráteis de controle da mesma composição, mas o interpolímero de etileno heterogêneo de controle, produzido com um catalisador ziegler-natta em lote, possui um dpiscb superior a 1,0.
