PURPOSE: A bioplastic composition is provided to improve flexibility, chemical resistance, and heat resistance by solving a compatibility problem between biodecomposable resins comprising bioplastics. CONSTITUTION: A bioplastic composition comprises a blend resin which is formed by mixing a polylactic acid resin and a polyhydroxyalkanoate resin. The polyhydroxyalkanoate resin comprises a repetitive unit represented by chemical formula 1. In chemical formula 1, R1 is a hydrogen atom, or a substituted or a non-substituted C1-15 alkyl group, and n is an integer of 1 or 2. In the blend resin, the content of the polylactic acid resin is more than the content of the polyhydroxyalkanoate resin. |
