This study focuses on the development of an alginate-based film enhanced with beeswax and zinc oxide nanoparticles (ZnO-NP) for food packaging applications. The alginate film was initially synthesized with the addition of beeswax and ZnO-NP, and its physical, mechanical, and barrier properties were characterized. Using response surface methodology (RSM), an optimal formulation was designed to enhance the film’s overall performance. The optimized film was achieved with 1.13% beeswax and 1.73% ZnO-NP, resulting in a moderate thickness of 0.076 mm, tensile strength of 5.70 MPa, and elongation of 33.45%. Additionally, the film exhibited good moisture resistance with a water vapor transmission rate (WVTR) of 25.11 g/m 2 ·day and moderate water solubility of 85.60%. These findings highlight the potential of beeswax and ZnO-NP as effective additives for alginate films, offering a solution for food packaging while maintaining key functional properties. • An alginate-beeswax-ZnO-NP film has been synthesized. • The addition of beeswax and ZnO-NP primarily enhances the barrier properties. • The optimized film was achieved using 1.13% beeswax and 1.73% ZnO-NP. • These findings emphasize the potential of beeswax and ZnO-NP as valuable additives for alginate films
