Resumo: Studies were carried out to produce biodegradable films from cassava starch. Two alternatives were investigated. In the first, films were obtained by starch gelatinization followed by thermopressing and glycerol was used at different concentrations as a plasticizer. In the second, starch acetate films were obtained by solubilization of cassava starch acetate in organic solvents, followed by casting on a glass plate and drying at room temperature. The films obtained by gelatinization were transparent and resistant to traction. The starch acetate films were also transparent but breakable. The use of these starch acetate films in paper impregnation improved the mechanical properties of the paper.
