Active packaging is a type of packaging that interacts with the contents to extend shelf life and maintain product quality. It can release or absorb substances, such as moisture or oxygen, to prevent spoilage. This technology is commonly used in food packaging to keep products fresh longer. Additionally, active packaging can include features like antimicrobial agents that inhibit the growth of bacteria or ethylene absorbers that slow down ripening in fruits. By enhancing the protective qualities of packaging, it helps reduce food waste and improves safety for consumers, making it an important innovation in the food industry.
