Abstract

"PROCESSO PARA SEPARAçãO DE FILMES MULTICAMADA UTILIZADOS PARA EMBALAGENS". A presente invenção de Certificado de Adição da PI 0202303-3 propõe a separação e recuperação integral dos filmes multicamada realizado através da introdução dos filmes multicamada em banhos de solventes, ácidos carboxílicos protonados e/ou água, aquecidos, combinados ou não entre si, com mais eficácia quando desfuncionalizados os adesivos, contidos entre eles, sendo atacados quimicamente pelos solventes, ácidos e a água."PROCESS FOR SEPARATION OF MULTI-LAYER FILMS USED FOR PACKAGING". The present invention of Certificate of Addition of PI 0202303-3 proposes the integral separation and recovery of the multilayer films carried out by the introduction of the multilayer films in heated, combined or not combined, solvent, protonated carboxylic acid and / or water baths. more effective when the adhesives contained between them are defunctualized, being chemically attacked by solvents, acids and water.
