Abstract: Customer expectations have shifted as a result of changing and improving product variety and evolving technology. This has resulted in significant growth in the printing industry, particularly in the packaging sector. The food industry, as well as the increasing need to preserve food for long periods of time, has necessitated the development of methods for preserving the freshness and safety of food products during their shelf-life. As a result, packaging systems were given special consideration in order to facilitate food processing, preserve food quality, extend shelf-life, and keep food from spoiling. Because of these systems, packaging has evolved beyond simply acting as a barrier between the food and the environment, and has also taken on roles such as releasing protective agents or removing unwanted matter. Microbial growth is one of the most important causes of food spoilage. Although heating, drying, fermentation, freezing, and adding antimicrobial agents have previously been tried to solve the problem, there are limitations, particularly when used with fresh food. A new generation of technologies is being introduced today to monitor the condition of products using a tiny sensor or label placed on the packaging. Smart packaging is a type of packaging that not only improves the basic functions of a product, but also responds to stimuli in its environment. Intelligent packaging and active packaging are the two main types of smart packaging. The purpose of this research is to investigate the concept of smart packaging, which has emerged as a result of increased competitiveness, digital interaction and consumer awareness, changes in consumer behaviour and expectations, and increased interest in product safety. As a result, it is obvious that cutting-edge smart packaging, which can connect to the Internet and has many channels of interaction, will create new business models and customer experiences, and will eventually replace conventional packaging, which has no interactions.
