Smart packaging refers to innovative packaging solutions that enhance the functionality and user experience of products. This technology can include features like sensors that monitor freshness, indicators that show when a product is spoiled, or materials that can change color to signal temperature changes. These advancements help improve product safety and reduce waste. Additionally, smart packaging can facilitate communication between the product and consumers. For example, it may include QR codes or NFC chips that provide information about the product's origin, usage instructions, or promotional offers. This interactivity helps consumers make informed choices and fosters a deeper connection with brands.
