Abstract Films based on rice flour were optimized using varying concentrations of guabiroba pulp (0–20%). After production using casting techniques, the films were subsequently characterized and compared to the control film. It was observed that the addition of guabiroba pulp enhanced the mechanical, optical, and water vapor barrier properties of the obtained films. Scanning electron microscopy and Fourier‐transform infrared spectroscopy tests indicated a good dispersion and interaction of the guabiroba pulp with the rice flour polymer matrix. Guabiroba pulp can therefore be used as a reinforcing additive in edible food packaging, among other purposes.
