Abstract

PURPOSE: Provided is a method for recycling multi-layered film waste for packing to use separated polypropylene, polyester, polyethylene and aluminum in production of new various products. CONSTITUTION: The method for recycling multi-layered film waste for packing includes the steps of: introducing high molecular ingredients of multi-layered film waste for packing to a reactor and treating them with an organic solvent; separating the high molecular ingredients of the multilayered film waste using the difference of solubility in the organic solvent according to temperature; adding an alkali aqueous solution or an acid aqueous solution to the reaction and dissolving aluminum by heating as needed to obtain a solution; and separating and recovering the high molecular ingredients and aluminum from the discharged material and the residue in the reactor.
