This study focused on the development and optimization of thermoplastic starch (TPS) and poly(butylene adipate‐co‐terephthalate) (PBAT) biobased active packaging films by incorporation with grape seed oil, alpha‐tocopherol, and rice husk. In the compound and film production step during extrusion for biobased active packaging film two variables, the antioxidant substance concentration (Grape seed oil, 0.5–4%; alpha‐tocopherol, 0.5–4%; rice husk, 1–5%), TPS concentration (60–90%) were optimized through response surface methodology (RSM) for highest tensile strength (MPa) and antioxidant activity (%) as responses. Among the resulting films, samples containing grape seed oil in particular exhibited an optimal balance, showcasing robust mechanical properties alongside potent antioxidant characteristics. Comprehensive analyses encompassing thickness, density, color, opacity, FTIR spectroscopy, total phenolic content, and energy consumption were conducted to assess the films' viability for potential deployment within the food industry. Based on the findings, it was determined that these biobased active packaging films made of TPS/PBAT held promise in safeguarding food products.
