Highly flexible PLA film was successfully produced by integrating effective reactive blending and economical film blowing process. Ductile PLA film having high elongation at break of ~250% and toughness of ~100 MPa was obtained by incorporating PBAT of 20 wt% via reactive blending with a small amount of chain extender (ESA) of only 1%. Films of PLA/PBAT/1%ESA exhibit potential as packaging material; their mechanical and optical properties are comparable with or even exceed some existing films used in the market.
