Millets have re-emerged as important crops in addressing food safety, climate resilience, and nutritional challenges, especially in areas that are arid or semi-arid. As customer demand of gluten-free, functional, and healthful foods has increased, the market for value-added millet-based goods has grown quickly. However, their shelf life and market potential have been constrained by the absence of suitable packaging solutions. This chapter offers a thorough analysis of packaging choices for millets and their derivatives, looking at both sustainable and traditional plastic-based approaches. The mechanical, barrier, and environmental properties of biodegradable and bio-based materials, such as starch-based films, polylactic acid (PLA), polybutylene adipate-co-terephthalate (PBAT), and polyhydroxyalkanoates (PHA), are investigated. Nanotechnology’s ability to improve packaging functionality, specifically, nanoclay-reinforced bio composites, is evaluated. Applying active and intelligent packaging technologies, such as pH-sensitive indicators, oxygen scavengers, and antimicrobial coatings, to extend shelf life and enhance product safety is also being researched. Alongside government measures encouraging the adoption of sustainable packaging, packaging options specifically designed for millet-based baking products, beverages, infant foods, and ready-to-cook items are assessed. The chapter emphasizes the need for integrated post-harvest processes and innovative materials to ensure millet product quality, reduce spoilage, and advance circular economy goals in the food packaging sector.
