Biopolymers and Biomaterials

Edible Films & Smart Food Packaging

Edible films and smart food packaging introduce environmentally friendly alternatives that enhance food safety, extend shelf life, and reduce plastic waste. Formulated from natural biopolymers such as starch, proteins, pectin, alginate, and cellulose derivatives, these materials create thin, biodegradable layers that safely contact or coat food products. Edible films provide barriers against moisture, gases, and microbial contaminants while allowing the incorporation of natural antioxidants, antimicrobials, and nutrients. Smart packaging technologies integrate sensors and indicators that respond to freshness levels, temperature changes, or spoilage markers, giving consumers and manufacturers real-time information about food quality. These innovations support sustainable supply chains by reducing waste and improving storage efficiency. Advances in material engineering focus on enhancing mechanical strength, transparency, and water resistance to match industrial standards. As global markets shift toward sustainable packaging solutions, edible and intelligent materials provide powerful tools for improving food security, minimizing environmental impact, and delivering eco-conscious innovations.
