The objective of this work was to develop biodegradable films using fibrous residue from the extraction of cassava starch and to investigate its effect as a reinforcement agent in polymeric films. Micrographs (SEM) showed that the obtained films presented smooth surfaces with no cracking. The addition of fibers affected the properties of the films significantly ( p < 0.05), reducing water vapor permeability values (from 8.63 ± 0.15 × 10 −11 g.m.m −2 .s −1 .Pa −1 to 3.33 ± 0.16 × 10 −11 g.m.m −2 .s −1 .Pa −1 ) and increasing the maximum tensile strength (from 1.23 ± 0.15 MPa to 7.78 ± 0.83 MPa). These results encourage the use of cassava bagasse as a reinforcement in the production of green composites as packaging. © 2018 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2019 , 136 , 47224.
