Abstract

filme reciclável para termoformação. trata-se de filmes recicláveis que têm pelo menos uma primeira camada que contém um polietileno de alta densidade, uma segunda camada que contém um polietileno de alta densidade e uma resina de hidrocarboneto, e uma terceira camada que contém um polietileno de alta densidade pode ser usada para termoformar componentes de embalagem. a estrutura de filme é vantajosa visto que pode ser mais facilmente termoformada do que filmes de polietileno de alta densidade tradicionais e pode manter o formato assumido durante a termoformação, exibindo deformação ou encolhimento mínimo.
