Abstract
"PROCESSO PARA SEPARAçãO DE FILMES MULTICAMADA UTILIZADAS PARA EMBALAGENS". Refere-se a invenção a um processo de separação de filmes multicamada, contendo filmes poliméricos unidos a um filme central de alumínio e/ou a um filme central de papel, cuja separação é realizada através da introdução dos filmes em banhos de solvente orgânico aquecido, com temperaturas e tempos pré-estabelecidos para cada tipo de material a ser separado, sob pressão atmosférica, permitindo a recuperação integral de cada filme, podendo ser reutilizado na fabricação de artigos diversos pelos processos comuns de reciclagem."PROCESS FOR SEPARATION OF MULTI-LAYER FILMS USED FOR PACKAGING". The invention relates to a multilayer film separation process containing polymeric films bonded to an aluminum central film and / or a paper central film, which is separated by introducing the films into heated organic solvent baths. with pre-set temperatures and times for each type of material to be separated under atmospheric pressure, allowing the full recovery of each film and can be reused in the manufacture of various articles by common recycling processes.
