The study aimed to prepare cornstarch-chlorophyllin (CS-Chl) composite films with coconut oil (CO), oregano essential oil (OEO), and beeswax (BW) at percentages of 0.5 %, 1.0 % and 1.5 %, to address the key limitation of the hydrophilic nature of the CS-Chl matrix, and the physiochemical, structural and photoactive antibacterial properties of the films were evaluated. The moisture content, water solubility, swelling ability, and water vapor permeability were significantly reduced in all CO
