• PLA/PBAT blend
• thermal stability
• storage modulus
• creep deformation

In the case of poly(lactic acid)/poly(butylene adipate-co-terephthalate) (PLA/PBAT) blend, thermal stability increased as higher PBAT content was blended and it is confirmed that stiffness of PLA/PBAT blend has been improved by increasing the value of storage modulus as addition of CaCO3. From the creep test of PLA/PBAT/CaCO3 blends, the deformation resistance decreased rapidly at lower temperatures as CaCO3 increased. Thus, in the case of application at more than 60 degrees C, it was considered that PLA/PBAT blend has a high resistance to deformation than pure PLA.
