BIODEGRADABLE RESIN COMPOSITION

摘要

A biodegradable resin composition is provided to ensure good productivity and workability, and excellent sanitation and safety, to increase an organic compound of soil by easily being decomposed, and to prevent the environment contamination. A pellet-type biodegradable resin composition is manufactured by the steps of: (S1) mixing starch 40~80 weight%, plasticizer 1.5~25 weight% and inorganic filler 5~40 weight% in a high speed mixer and removing moisture; (S2) adding aliphatic polyester 5~50 weight% and lubricant 0.3~11 weight% to the mixture, mixing them and removing moisture; and (S3) injecting the moisture-removed raw material in a twin extruder, dying after cutting the material discharged through dice, or cutting after transferring the discharged strand through a conveyor belt and drying it to manufacture the pellet type.
