PURPOSE: A biodegradable film composition is provided to shorten manufacturing time, prevent decrease of biodegradation, and improve mechanical property. CONSTITUTION: A biodegradable film composition comprises aliphatic polyester-based polymer which is reformed to reactive modifier, thermoplastic starch, peroxide, and antioxidant. The aliphatic polyester-based polymer which is reformed to reactive modifier includes 0.5-2.5 parts by weight of reactive modifier, 0.1-0.6 parts by weight of peroxide, and 0.3-0.5 parts by weight of antioxidant based on 100.0 parts by weight aliphatic poly ester based polymer. The aliphatic polyester-based polymer has a melt index(2.16kg/cm^2, 190deg.C) of 5-30g/10min. |
