By leveraging advanced technologies, smart packaging addresses the increasing demand for transparency and personalization, making it a significant trend in the packaging industry. As smart packaging continues to evolve, enhance consumer experience and improve product safety, its potential to transform supply chains, enhance sustainability, and improve consumer engagement becomes increasingly evident. 

How Is Smart Packaging Being Implemented?

The industry is making significant strides in implementing smart packaging by integrating advanced technologies. These technologies give manufacturers and consumers more visibility and control over the product's condition, authenticity, and impact on the environment. Smart packaging incorporates various technologies and features, and it can be broadly classified into the following types: 

Active Packaging: Active packaging is a way of smart packaging which involves incorporating components or materials that interact with the product or its environment to extend shelf life, improve product quality, or enhance safety. Some common examples of active packaging technologies are: 

• Oxygen scavengers: These components absorb oxygen within the package, reducing oxidation and extending the shelf life of perishable goods like food and beverages. This also ensures the freshness of the edibles stored inside. Some active smart packaging systems can also control humidity levels inside the package to prevent moisture-related degradation of products. 
• Ethylene and Antimicrobial absorbers: Ethylene is a gas naturally produced by fruits and vegetables, which accelerates their ripening and spoilage. Ethylene absorbers in smart packaging help slow the ripening process, extending the freshness of the produce. Adding antimicrobial agents into the smart packaging makes it possible to restrict the growth of bacteria, mold, and other microorganisms, preserving the product's freshness and safety.

Intelligent Packaging: Intelligent packaging is another popular form of smart packaging, which involves integrating electronic components like sensors, microchips, or indicators into the packaging to provide real-time information about the product or its environment. Examples of intelligent packaging technologies include: 

• Temperature sensors: These sensors can monitor and transmit temperature data to ensure products stored in smart packaging are within safe temperature ranges during transportation and storage. Time-temperature indicators, or TTIs, can also be used to monitor temperature change. TTIs are smart labels that change color based on time and temperature exposure, giving consumers an indication of product freshness and safety. 
• RFID (Radio-Frequency Identification) and NFC tags: RFID package tracking tags are widely employed to track and trace products, ensuring their authenticity and preventing counterfeiting. These tags are used for tracking and tracing products throughout the supply chain and can also provide consumers with additional information or promotions through their smartphones. 
• QR codes and augmented reality (AR): These technologies allow consumers to scan their smart packaging to access digital content, such as product information, usage instructions, or interactive experiences.
