This comprehensive review explores the emerging trends in biomaterials for sustainable food packaging, addressing the growing environmental concerns and the negative impacts of traditional plastic packaging. The study examines various biomaterials, including biodegradable polymers, ceramics, composites, and metal alloys, highlighting their potential to replace conventional plastic packaging and reduce environmental damage. The integration of nanotechnology is also discussed, emphasizing its role in improving barrier qualities, introducing antimicrobial properties, and enhancing smart packaging features. The review further delves into edible coatings and films made from biodegradable polymers, which offer new sensory experiences while extending product shelf life. The use of biomaterials derived from food processing and agricultural waste is emphasized, supporting environmentally responsible production methods. The report highlights the increasing use of recyclable and biodegradable packaging by the food industry, aligning with the concepts of a circular economy. Despite encouraging trends, challenges such as cost-effectiveness, technological constraints, and scalability of biomaterial production remain. The review concludes by emphasizing the critical role of biomaterials in guiding the food industry toward sustainability and the need for ongoing research and development to address environmental issues and meet the growing demand for eco-friendly packaging options.This comprehensive review explores the emerging trends in biomaterials for sustainable food packaging, addressing the growing environmental concerns and the negative impacts of traditional plastic packaging.
