This invention discloses a food-grade antibacterial packaging paper based on biomass conversion and its preparation method, relating to the field of papermaking technology. The packaging paper uses areca leaf mechanical pulp rich in lignin and natural phenols as a substrate. After alkali treatment and oxidase activation of the phenolic hydroxyl groups on the fiber surface, a chitosan-tea polyphenol layer is coated onto its surface, followed by ionic crosslinking and interfacial co-crosslinking with phytic acid to construct a dense fiber-coating network structure. This improves the paper's mechanical strength, water and oil resistance, and inhibition of common pathogenic bacteria while maintaining its renewability, biodegradability, and food contact safety.
