The extensive use of non-biodegradable plastics has been causing serious environmental pollutions because of the degradability issue from especially consumable food packaging. In this research, biodegradable materials i.e., Poly(lactic acid) (PLA) and Polybutylene succinate (PBS) are chosen for the study. PLA/PBS foam was prepared using Azodicarbonamide (ADC) and Poly(ethylene glycol) (PEG) 20 wt% as a blowing agent and plasticizer, respectively. Foamability of different content PLA/PBS blend were investigated. PLA/PBS foam were characterized by Water absorption, Flexural testing, Scanning Electron Microscope (SEM). Flexural properties of PLA/PBS foam (70/30) showed the highest flexural modulus of 384 MPa due to the smallest cell size while PLA/PBS foam (20:80) showed the highest flexural stress of 11 MPa. PLA/PBS foam showed uniform cell size distribution. PLA/PBS foam had water absorption ability due to its porous structure.
