Abstract

"APERFEIçOAMENTO INTRODUZIDO EM FILMES MULTICAMADAS COEXTRUDADOS INCLUìNDO FORçAS DE UNIãO INTRALAMINAR CAPAZES DE SEREM ROMPIDAS". Estruturas de filmes multicamadas são reveladas possuindo uma primeira camada de material polímero selante, uma segunda camada compreendendo uma camada de união capaz de ser rompida e uma terceira camada compreendendo uma poliolefina adesiva. A primeira camada compreende de aproximadamente 1% a aproximadamente 10% da espessura total da estrutura de filme multicamada, possui uma espessura máxima de aproximadamente 0,25 mils e possui um desvio de uniformidade de espessura de menos que aproximadamente 20% da espessura média da primeira camada.
