Carbohydrate-based biodegradable films offer an eco-friendly alternative to conventional petroleum-derived packaging for agricultural commodities. Derived from renewable polysaccharides such as starch, cellulose, chitosan, pectin, alginate, pullulan, and xanthan gum, these exhibit favorable biodegradability, film-forming ability, compatibility with food systems. This review presents a comprehensive analysis of recent developments in the preparation, functionalization, application polysaccharide-based packaging. Emphasis is placed on emerging fabrication techniques, including electrospinning, extrusion, layer-by-layer assembly, which have significantly enhanced mechanical, barrier, antimicrobial properties materials. Furthermore, incorporation active compounds antioxidants antimicrobials has improved performance shelf-life packaged goods. Despite notable advancements, key limitations moisture sensitivity, poor mechanical durability, high production costs persist. Strategies polymer blending, nanofiller incorporation, surface modification are explored potential solutions. The applicability fruits, vegetables, dairy, grains, meat products also discussed. By assessing current progress future prospects, this underscores importance carbohydrate-based promoting sustainable systems, reducing environmental impact through advancement circular bioeconomy principles development.
