*2.10. Tensile Test*

The tensile tests of the TPS, TPS bio-composite and TPS hybrid bio-composite films were performed by Instron machine model-5582 (Norwood, MA, USA),according to ASTM D 638 Type V. The samples were tested with a crosshead speed of 10 mm/min to obtain the stress–strain curves. From the data, the tensile properties, such as tensile strength, Young's modulus, elongation at break and tensile toughness, were determined.
