Abstract

LA PRESENTE INVENCION SE REFIERE A UN PRODUCTO FABRICADO QUE COMPRENDE UN AGENTE DESOXIGENANTE Y UN POLIMERO CON CONTENIDO DE ACIDO LACTICO. DICHO PRODUCTO PUEDE TENER LA FORMA DE UNA PELICULA, UN REVESTIMIENTO, UNA JUNTA, UN FORRO, UN INSERTO, UN PRODUCTO DE ESTANQUEIDAD O UN CONJUNTO DE FIBRAS. LA PELICULA SE COMPONE DE AL MENOS UNA CAPA QUE CONTIENE UN AGENTE DESOXIGENANTE Y DE AL MENOS UNA CAPA QUE CONTIENE UN POLIMERO CON CONTENIDO DE ACIDO LACTICO. ESTE PUEDE UTILIZARSE PARA LA FABRICACION DE UN EMBALAJE DESTINADO A CONTENER UN PRODUCTO SENSIBLE AL OXIGENO, TAL COMO UN PRODUCTO ALIMENTARIO. EL POLIMERO CON CONTENIDO DE ACIDO LACTICO BLOQUEA LA MIGRACION DE SUBPRODUCTOS DE LA DESOXIGENACION QUE PROVOCAN OLORES. LA PRESENTE INVENCION SE REFIERE TAMBIEN A UN PROCEDIMIENTO QUE CONSISTE EN UTILIZAR LA PELICULA COMPUESTA DE AL MENOS UNA CAPA QUE CONTIENE UN AGENTE DESOXIGENANTE Y DE AL MENOS UNA CAPA QUE CONTIENE EL POLIMERO CON CONTENIDO DE ACIDO LACTICO Y EN EXPONER ESTA PELICULA A UNA RADIACION ACTINICA. LA INVENCION SE REFIERE FINALMENTE A UN PROCEDIMIENTO DE REDUCCION DE LA MIGRACION DE COMPUESTOS SIGNIFICATIVOS EN TERMINOS DE PROPIEDADES ORGANOLEPTICAS.
