Abstract: A method for recycling an aluminum-deposited waste packaging film is provided to obtain recycled materials with good miscibility and impact resistance at low cost by reacting and extruding the waste film mixture, a compatibilizer, and functional resin. The method for recycling an aluminum-deposited waste packaging film comprises a step of melting and mixing the waste film mixture including the aluminum-deposited waste packaging film and a step of adding a compatibilizer and high-density polyethylene resin with molecular weight distribution of a bimodal structure, to the melted mixture and then reacting and extruding the melted mixture, the compatibilizer, and the polyethylene resin. The polyethylene resin has a maximum molecular weight distribution value in two ranges of 16,000~24,000 and 120,000~140,000. The waste film mixture is formed by mixing aluminum-deposited polypropylene and nylon waste packaging films.
