Introduction
Nanomaterials are revolutionizing the field of packaging by dramatically improving the core physical and protective properties of materials. Their integration significantly enhances mechanical strength, barrier performance against gases and moisture, and thermal stability. Nanomaterials provide advanced, long-lasting functionalities such as potent antimicrobial and antioxidant effects, which are crucial for extending the shelf life and safety of perishable products. A transformative aspect is the enablement of intelligent, responsive packaging systems. This includes the development of visual indicators for real-time freshness monitoring, temperature-sensitive controls for adaptive protection, and mechanisms for the precise, controlled release of active compounds. These multifaceted innovations collectively drive the evolution of packaging towards high performance, multifunctionality, and greater environmental sustainability. This Special Issue is dedicated to presenting the latest scientific advances and applications of nanomaterials in this area, highlighting novel materials, innovative design strategies, and their broader implications for the future of smart and sustainable packaging solutions.
