Smart packaging has emerged as a transformative approach in modern food systems, enabling real-time monitoring of food quality, safety, and freshness throughout the supply chain. Unlike conventional passive packaging, smart packaging integrates sensing, communication, and response mechanisms to detect biochemical and environmental changes in food products. Freshness sensors, biosensors, and intelligent indicators play a crucial role in extending shelf life, reducing food loss, and enhancing consumer trust. This review critically examines recent developments in smart packaging and freshness sensor technologies, focusing on sensor types, functional materials, data integration, and industrial applications. Emphasis is placed on sustainability, scalability, and the role of intelligent packaging in addressing global food safety challenges. Current limitations, regulatory concerns, and future research directions are also discussed to provide a holistic understanding of the evolving smart packaging landscape.

Smart packaging and freshness sensor technologies represent a transformative approach to food quality monitoring, offering real-time, accurate, and accessible information across the food supply chain. Advances in materials, fabrication methods, and sensor integration have enabled intelligent packaging systems that enhance food safety, improve supply chain efficiency, and support sustainability objectives. Their application across diverse food categories demonstrates strong potential for reducing uncertainty in freshness assessment and minimizing food loss and waste.
However, achieving large-scale implementation will require addressing technical, economic, and regulatory challenges while ensuring environmental responsibility. Continued innovation, supported by interdisciplinary research and harmonized policy frameworks, will be essential for advancing smart packaging toward widespread commercial adoption. As these technologies mature, they are poised to play a vital role in creating more resilient, transparent, and sustainable global food systems.
