The development of several novel food packaging techniques is seen in the market that help the consumer monitor their quality, safety, integrity, cleanliness, freshness, and purity until they are being consumed. In addition to this, there is a need to minimize food corruption, counter-theft, spoilage, contamination, and efficient food safety communication. Several current technologies for packaging, such as intelligent packaging and active packaging, have been established to meet this requirement. In this review paper, we discussed various types of intelligent packaging systems like indicators, sensors and data carriers. Indicators indicate the current status of food products from the inside by giving visual signals like colour change. Sensors, which are digital in nature, detect the changes that occur in the product with the help of transducers and signal processors. Finally, a brief discussion about data carriers and their classification, such as Bar codes, QR codes, Radio Frequency Identification Devices, and Near Field Communication Systems, is given. These systems help to track the product in supply chain and inventory management.
