Bionanocomposite packaging eco-friendly alternatives with enhanced characteristics. This study aimed to develop a bionanocomposite intelligent packaging. Sodium alginate, gelatin, Curcumin (Cur), glycerol, and Nanoclay (NC) films were prepared. The influences of nanoclay and curcumin on the surface, optical, mechanical, chemical, barrier, and pH-indicating properties were studied. The results showed that the lightness of films was reduced by 1.28 folds compared to NC (control) film, while the yellowness of films increased by 5.82 folds. Film transparency was reduced by 9.3 folds and a 3.46 folds increase in UV barrier properties was observed compared to NC (control) film. The highest tensile strength and elongation at break was observed was 38.63±0.93MPa and 3.89±0.69%. The hydrophobicity of films increased upto 87.36. N-H, C-O, and O-H covalent bonds are observed between biopolymers. The water vapour barrier and oxygen permeability increased by 8.95% and 93.06% respectively when compared to Curcumin (control). A colour change was observed from orange to red in alkaline conditions. The biodegradation study showed that all developed films biodegraded 100% within 1 month. The films had enhanced mechanical, barrier, and pH-indicating properties. Therefore, it can be used as a potential intelligent food packaging material to improve the quality of food products.
