Mechanical behavior of TPS films was carried out using two
different devices. Tensile tests were performed in an Instron 3369
universal mechanical testing system (Instron, USA) using a cross-
head speed of 2 mm/min and a load cell of 50 N. Ten test specimens
(13 ? 100 mm) were assayed for each film formulation and stress-
strain curves were calculated from load-displacement data. Young’s
modulus (E), maximum tensile strength (sm) and elongation at
break (εb) were calculated according to ASTM D882-00 standard
method. Besides, resilience modulus (Ur) and yield strain (εy), as
well as toughness, were also obtained.
