The present study examined the impact of dielectric barrier discharge cold plasma treatment on the physicochemical characteristics of taro peel starch (TPS) and its films. This work reports for the first time on using native and modified TPS in the casting procedure to develop packaging films. The results showed that, as plasma exposure voltage and treatment time prolonged, the pH, 955 cm−1/1022 cm−1, % crystallinity, and turbidity of TPS significantly decreased, while amylose content, solubility, and 1047 cm−1/1022 cm−1 of TPS increased considerably. Despite this, modified TPS‐based films have comparatively smooth and homogeneous surfaces. Moreover, the modified starch‐based film exhibited the lowest water vapor permeability, elongation at break, and solubility, while highest opacity and tensile strength.
