Abstract
The objective of this study was to obtain and characterize biodegradable films composed of ternary blends of biopolymers. The films produced were composed of chitosan, potato starch and sodium alginate, based on an experimental planning employing ternary mixture plan. The filmogenic solutions were obtained by the casting technique, with the dry matter fixed at 2%. The plasticizer used was glycerol and its percentage was fixed at 20%, in relation to the dry mass of biopolymer. After the production of biofilms, these were cut into specimens, to perform the mechanical characterization. An analysis of variance (ANOVA) was performed to obtain the models and the F Test was used to verify their statistical significance.
