Responses for the dependable parameters FT, TS, EAB and YM are shown in Table 2, and the effect that CF and CG caused in these properties can be observed in Table 3. Film thickness (FT) increased linearly with increasing CG and CF concentrations, with values ranging from 0.111 mm to 0.298 mm. Results for Young’s Modulus (YM), which is related to the stiffness of the film, indicated the same positive and linear effect caused by CF, while CG had the opposite effect (Fig. 2). Elongation at break was increased with increasing the CG ,as illustrated in Fig. 3, where the greatest value of EAB (282.75%) corresponds to Test 10, with no CF added. Alves et al. (2015) also reported that the addition of bovine gelatin into corn starch films lead to higher FT and EAB values. In contrast, the incorporation of CF into the film linearly decreased the EAB
