Intelligent packaging systems represent a modern technological advancement in food packaging that combines traditional protective functions with advanced monitoring, sensing, and communication capabilities. Unlike conventional packaging, which mainly serves as a passive barrier against environmental contamination, moisture, oxygen, and physical damage, intelligent packaging interacts with the food product and its surrounding environment. It is designed to detect changes in food quality, provide real-time information to manufacturers, retailers, and consumers, and improve food safety, traceability, and shelf-life management. With increasing global food demand, complex supply chains, and consumer awareness about food safety, intelligent packaging is becoming a crucial component of emerging food technology. An intelligent packaging system typically includes sensors, indicators, data carriers, and communication devices integrated into packaging materials. These components monitor various parameters such as temperature, gas composition, microbial growth, freshness level, and physical damage during storage and transportation. The system provides visual signals or digital data that help in assessing food quality without opening the package. This technology is widely being explored by food manufacturing companies such as Nestlé to improve quality assurance and supply chain transparency. One major type of intelligent packaging is indicator-based packaging. Indicators are simple devices that provide visible signals about the condition of food products. Time-temperature indicators (TTIs) are commonly used to monitor temperature
