This comprehensive review explores emerging trends in sustainable food packaging using biomaterials, addressing environmental concerns and the negative impacts of traditional plastic packaging. It highlights the potential of biodegradable polymers, ceramics, composites, and metal alloys as environmentally friendly alternatives. The integration of nanotechnology enhances barrier properties, antimicrobial effects, and smart packaging features. Edible films and coatings made from biodegradable polymers offer new sensory experiences and extend product shelf life. The review emphasizes the use of biomaterials derived from food processing and agricultural waste, supporting sustainable practices while reducing resource use and waste. The food industry is increasingly adopting recyclable and biodegradable packaging, aligning with circular economy principles. Global market trends show growing consumer demand and regulatory pressure for sustainable packaging. Despite these trends, challenges such as cost-effectiveness, technological constraints, and scalability of biomaterial production remain. The review concludes that biomaterials play a critical role in guiding the food industry toward sustainability, emphasizing the need for ongoing research and development to address environmental issues and meet the growing demand for eco-friendly packaging. The review also discusses the functions of various biomaterials, including biodegradable polymers, ceramics, composites, metals, and nanomaterials, highlighting their benefits and challenges. It explores the role of nanotechnology in enhancing biomaterial performance and the potential of edible films and coatings in reducing packaging waste. The review also examines global market trends, the growth of bioplastics, and the increasing use of compostable and recyclable packaging. Challenges include balancing cost-effectiveness with sustainability, ensuring regulatory compliance, and improving the scalability of biomaterial production. The review concludes that collaboration between industry, research, and government is essential to advance sustainable food packaging solutions.This comprehensive review explores emerging trends in sustainable food packaging using biomaterials, addressing environmental concerns and the negative impacts of traditional plastic packaging.
