The stiffness of the PLA/PBAT films, determined by the elastic
modulus (EM), showed a similar trend as the TS. On the contrary,
the elongation at break (E) of PLA film was 5%, which indicates that
PLA film is brittle with low flexibility, and that od PBAT film was
137% indicating that PBAT film is resilient with high flexibility. The
E of PLA/PBAT blend films showed that the flexibility of PLA film has
increased by blending with PBAT, and it also showed that the
flexibility of PLA/PBAT blend films increased with the increase in
the PBAT content
