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.

Abstract: A method for manufacturing recycled high density polyethylene is provided to economically produce recycled high density polyethylene having mechanical properties equal to or better than new high density polyethylene by recycling waste high density polyethylene. The method for manufacturing recycled high density polyethylene comprises the steps of: mixing 20-40wt% of waste high density polyethylene with 60-80wt% of new high density polyethylene having a bimodal molecular weight distribution; adding a peroxide cross-linking agent to the mixture; and melt-mixing the admixture at 165-175°C and at a speed of 35-45RPM for 8-12minutes. The peroxide cross-linking agent is dicumyl peroxide or perbutyl peroxide.
