Plastic packaging has been widely criticized due to the environmental pollution it entails. Biopolymer-based films could provide an interesting eco-friendly alternative. This study aimed investigate effect of plasticizer type on physicochemical and mechanical properties gelatin, pectin, starch, gelatin/pectin, gelatin/starch, starch/pectin-based films. Films were prepared using casting method. Among six types studied, gelatin/pectin-based film plasticized with sorbitol displayed best functional properties. Tensile strength elongation at break 52.46 MPa 19.80%; moisture content, water vapor permeability, resistance 19.96%, 3.24 × 107 g s–1 m–1 Pa–1, respectively. Mentha pulegium Lavandula angustifolia essential oils incorporated into selected their effects film's characteristics evaluated. The incorporation resulted in enhanced antibacterial properties, lower reduced Practical applications have attracted widespread attention as alternative plastic packaging. In this study, we demonstrated that 30% good matrix important antimicrobial activity adequate characteristics. combination be used bioactive preserve prolong shelf life food.
