Abstract Sustainable packaging materials with inherent antimicrobial and antioxidant properties are increasingly demanded for food preservation. In this study, chitosan/polyacrylamide/tea tree oil (CS/PAAm/TTO) films were developed via gamma irradiation, varying both the irradiation dose (10–50 kGy) TTO concentration (25–100 μL) to attain an optimized formulation superior performance. regard, optimization was accomplished atomic force microscopy (AFM) through assessing surface morphologies of prepared at different doses, which identified 30 kGy as optimal incorporation. On other hand, comprehensive characterizations using Fourier transfer infrared spectroscopy, x‐ray diffraction, thermogravimetric analysis, contact angle measurements revealed that increasing content enhanced hydrophobicity improved mechanical properties. More specifically, increased significantly higher levels, indicating hydrophobicity, while tensile tests demonstrated flexibility. addition, assays confirmed efficacy against a range pathogens, 1,1‐diphenyl‐2‐picryl hydrazyl assay indicated notable activity, IC50 value 111.45 μg/mL formulation. These findings underscore potential biofilms advanced, multifunctional materials, offering promising environmentally friendly alternative conventional Highlights Green sustainable.
