Abstract: Fruits typically have a short shelf life after harvest, making them susceptible to spoilage, especially during transportation. The purpose of this research was to create antibacterial packaging to extend the shelf life of fruits by coating paper packaging with silver nanoparticles (AgNPs). These AgNPs were synthesized using a green method that utilized orange peel extract as a reducing agent. The results from absorbance, particle size, and morphology analysis revealed that the AgNPs exhibited maximum absorption at 425 nm and had an average size of 128.1 ± 26.6 nm, and showing good dispersion with spherical shape. Paper packaging coated with AgNPs effectively inhibited the growth of both gram-positive and gram-negative microorganisms, thereby reducing the risk of fruit spoilage. Furthermore, this research investigated the physical characteristics. The findings indicated that AgNPs-coated paper packaging extended the shelf life of tomatoes in comparison to uncoated paper packaging. This implies that the antibacterial properties of the AgNPs contributed to preserving the quality of tomatoes for a longer duration. In conclusion, the development of antibacterial packaging by coating paper with silver nanoparticles synthesized using green synthesized orange peel extract as a reducing agent has the potential to inhibit bacterial growth and prolong the fruit's shelf life
