Poly lactic acid(PLA) and poly butylene adipate-co-terephthalate(PBAT) film was prepared using a twin extruder. PLA (25%) and PBAT (75%) were mixed with various ratio of chain extenders, such as Joncryl® and hexamethylene diisocyanate(HDI) to improve the mechanical and thermal properties of produced bio composite films. Tensile strengths of films were steadily increased with increasing ratio of chain extender. The tensile strength of control films was about 25 MPa, and the tensile strength of films with combined chain extenders was above 40 MPa. The films with Joncryl ® resulted in improved tensile strength, while the film with HDI alone showed improved percent elongation at break. By adding chain extenders into PLA/PBAT resin, the cold crystallization temperature (Tcc) and decomposition temperature (Td) of the produced bio composite films increased. It revealed that the addition of two types of chain extenders was efficient way to get PLA/PBAT film with improved strength and elongation.
