Biodegradable materials can use in many products such as textile, packaging, agriculture and others. PLA and PBSA have been getting more interest due to their biodegradable property. PLA is a hard and transparent polymer with the additional of PBSA or copolyester can increase the flexibility, processability and thermal properties of the compound. The PLA biodegradable process needs water to be hydrolyzed and composed while PBSA can be hydrolyzed and biodegraded faster. In this study, PLA and PBSA were blended at 100:0, 90:10, 80:20, 70:30, 60:40, 50:50 and 0:100. The blends polymer produced from extrusion process and compressed for characterize. Thermal, mechanical and physical properties were measured.
