Test filmstrips (8 × 2.5 cm) were cut from preconditioned samples (23°C; 75% RH) and mounted between the grips of
the probe A/TGT of the TA.XT2i texturometer (Stable Micro Systems, UK). The tests was conducted according to the ASTM D882-00 (2001) method [9]. Ten specimens was tested for the best antibacterial and antioxidant formulation. Average film thicknesses of the preconditioned samples (75% RH, 23°C) were obtained using a flat parallel surface micrometer with 1p.m resolution. Five measurements was taken at three different randomly selected positions.
