Bio-based active packaging has been demanded for replacing the petroleum plastics and extended shelf-life of perishable food. In this study, fish gelatin-carrageenan (GC) blended films were incorporated with torch ginger (Etlingera elatior) inflorescence carbon dots (TGCDs) at varying concentrations (1–5%, w/w based on polymers). Physicochemical properties and characteristics of resulting films were investigated. In addition of TGCDs, the film appearance became more yellow (+b*) with decreased lightness (L*) and increased redness (+a*). Thickness of all films was in the range of 0.031 – 0.039 nm. TGCDs addition at 3% significantly increased elongation at break (EAB) (P < 0>
