The present work aims to develop active and biodegradable coating from polyvinyl alcohol (PVOH), agarose, and D‐glucose combined with Sonneratia ovata leaf extract (SO) for prolonging the shelf life of Grande Naine banana. In addition, the PVOH/agarose/D‐glucose/SO coating films were prepared through solvent evaporation method before applying it to banana for the purpose of characterizing vital properties required for food packaging materials. Our findings showed that the addition of SO in the polymer blend based on PVOH/agarose/D‐glucose (PAD) imparts outstanding flexibility, UV‐barrier, antioxidant, and bactericidal properties of the resultant film. It was also found that the modified coatings with SO could prolong the shelf life of bananas up to day 6th storage at 25°C. The visual appearance, development of peel color, weight loss, total soluble sugar content, and pH of banana samples confirmed that PAD‐SO coating could prevent ripening of bananas during the storage period as compared to uncoated and PAD‐coated fruits. These results suggest that PAD‐SO active coatings are a promisingly potential material for extending the shelf life of fruits.
