The tensile (stress/strain) was measured in a universal testing machine (Model WDW -300E Time Group, Inc.) as per the ASTM D1708-10 method. Five samples of each type of film were prepared. The initial grip separation and traction speed were set as 22 mm and 12.5 mm/min, respectively, with a 150 kgf load cell. Five samples were analyzed for each test, and all testing occurred at room temperature (approximately 25 °C). Young's modulus (E) and modulus of elasticity were determined in the linear region of the graphics by performing linear regression. Data were analyzed by using the Origin Pro 8.1 software.
