Abstract

"APERFEIçOAMENTO INTRODUZIDO EM FILMES PARA APLICAçãO EM EMBALAGENS CONTENDO CAMADAS FORMADOS POR POLIéSTER E NáILON OBTIDOS POR COEXTRUSãO". Estruturas termoformáveis coextrudadas multicamadas para aplicações em filmes para embalagens. As estruturas multicamadas possuindo ao menos uma primeira camada compreendendo um polietileno tereftalato, uma segunda camada de um primeiro adesivo compreendendo uma mistura de ao menos uma resina a base de acrilato e também uma poliolefina modificada ou uma resina a base de acrilato modificada; uma terceira camada de uma barreira de oxigênio termoplástica. A barreira de oxigênio termoplástica pode compreender um copolímero de etileno/vinil álcool (EVOH), cloreto de polivinilideno, ou poliamida, preferencialmente uma mistura de poliamida contendo entre 1% e 29% de poliamida amorfa. A presente invenção pode ainda compreender ao menos 5 a 7 camadas termoplásticas.
