PURPOSE: A biodegradation molding material is provided to facilitate discard by biodegrading and to have no material property degradation of water resistance, oil resistance, and strength by containing a mineral filler or a plant filler. CONSTITUTION: A biodegradation molding material comprises 5-1000 parts by weight of mineral filler and/or 6-200 parts by weight of plant filler based on 100 parts by weight of aliphatic polyester. The aliphatic polyester is selected from polylactic acid, polycaprolactone, polyhydroxy butylate, polybutylene succinate, and polybutylene terephthalate. The mineral filler is selected from talc, carbonate, silica, and titanium oxide. Moreover, the biodegradation film comprises a core(100) including the biodegradation molding material and a printing layer(200) formed on the top of the core. |
