Abstract

EMBALAGEM DE RETORTA PRONTA PARA RECICLAGEM RESISTENTE AO CALOR. Um filme laminado à base de polipropileno adequado para embalagem de retorta que tem um filme externo, uma camada de barreira e uma camada de vedação. O filme de embalagem de retorta tem uma composição total que inclui altos níveis de polímeros à base de poliolefina e polímeros à base de polipropileno de modo que o material possa ser processado de modo eficaz em um processo de reciclagem de polipropileno. Vantajosamente, o filme retém as propriedades necessárias para suportar adequadamente o processo de retorta e produzir um produto embalado de alta qualidade e estável em prateleira.
