LLDPE / AL / LDPE SEPARATION LAYERS FOR RECYCLING LONG LIFE CARTON PACKAGING THROUGH A SOLUTION COMPOSED OF A MIXTURE OF ORGANIC AND INORGANIC ACIDS

摘要

SEPARATION PROCESS OF LLDPE / AL / LDPE LAYERS FOR RECYCLING LONG CARTONED PACKAGES THROUGH THE USE OF A SOLUTION COMPOSED BY A MIXTURE OF ORGANIC AND INORGANIC ACIDS. The present invention relates to a process for separating the LDPE / AL / LDPE layers in the recycling of long-life carton packs (ECLV), using an aqueous solution composed of a mixture of organic and inorganic acids, which is added by a compound with surfactant properties. The purpose of this used carton packaging treatment process is to enable the recycling of the materials that compose them by completely separating their constituent elements without altering their physical-chemical properties, while maintaining the integrity of these components. This process consists of a single step of immersing ECLV in a single solution, lasting 10 to 150 minutes, using temperatures between 25o C and 100o C
