Abstract

"PROCESSO DE DESCONTAMINAçãO DE POLIéSTER RECICLADO E USO DO MESMO". é descrito um processo de remoção de contaminantes de flakes de PET limpo utilizando atmosfera de ar seco a 120-200<198>C/3-30m¬ 3¬h/ponto de orvalho de -20 a -60n<0>C/por pelo menos 15 minutos e gás inerte a 200-250<198>C/0,1-30 m¬ 3¬/h/ por pelo menos 10 minutos, seguido da etapa de extrusão convencional (5), granulação em granulador (6) e cristalização. O polímero é processado em reator (4) para obtenção de uma resina reciclada com pureza e características físico-químicas adequadas para aplicação em embalagens alimentícias monocamada 100% de PET reciclado. As variáveis, tempo, temperatura e fluxo de ar ou gás são importantes para o controle da viscosidade, características ópticas e grau de descontaminação do polímero. Os padrões de pureza estabelecidos para proteção do consumidor e das propriedades organolépticas do produto envasado estão de acordo com os exigidos pelo FDA, ILSI e ANVISA. O uso do material em grânulos também é descrito.
