2.5.1. Mechanical Properties

The thickness of the films was determined using a Mitutoyo digital micrometer (Tester Sangyo Co., Ltd., Saitama, Japan). The mechanical properties were defined using a TA-XT Plus texture analyzer (Stable Micro Systems, Godalming, UK). The films were cut into 20 × 60 mm pieces with an initial distance of 40 mm and a proper tensile speed of 0.6 mm/s [16].
