Smart packaging refers to advanced packaging solutions that enhance the functionality of traditional packaging. It often incorporates technology to monitor the condition of the product inside, such as temperature, humidity, or freshness. This helps ensure that products, especially perishable items like food and pharmaceuticals, remain safe and effective for consumers. Additionally, smart packaging can include features like QR codes or NFC tags, allowing consumers to access information about the product, such as its origin or usage instructions. This technology not only improves user experience but also helps manufacturers track their products throughout the supply chain, enhancing overall efficiency and safety.
