Abstract The present review aims to analyze biodegradable packaging films, with a specific emphasis on their sources, the role of additives in enhancing their properties and functionality, and the processes involved in their development. While traditional biodegradable films are derived primarily from polysaccharides, proteins, lipids, or hydrocolloids, recent advancements have led to the incorporation of natural and synthetic additives to enhance their mechanical, barrier, and functional properties. The integration of nanocomposites, bioactive compounds, and plant-based extracts has significantly improved the antimicrobial, antioxidant, and physical characteristics of these films. Processing techniques such as extrusion and solution casting have also evolved to produce biodegradable films with properties comparable to those of conventional plastics, enabling large-scale production. Therefore, the current trends and prospects identified in this review could offer valuable insights to facilitate the adoption of sustainable practices within the food industry. Moreover, the findings can contribute to ongoing efforts in the innovation and advancement of eco-friendly biodegradable packaging materials.
