Smart packaging technology encompasses advanced materials, embedded electronics, sensors, indicators, and digital connectivity features that extend packaging functionality beyond traditional containment and protection. These innovative solutions transform passive packaging into interactive systems capable of monitoring product conditions, communicating with consumers and supply chain partners, extending shelf life, enhancing user experience, and providing authentication while potentially reducing environmental impact through optimized material usage.
Unlike conventional packaging serving primarily physical protection and marketing purposes, smart packaging actively participates in product quality preservation, supply chain management, and consumer engagement through various technological approaches. This evolution enables packaging to serve as a digital touchpoint throughout the product lifecycle—from manufacturing through distribution, retail, consumption, and disposal—providing valuable data while delivering enhanced functionality that addresses challenges in food waste, counterfeiting, medication adherence, and consumer information access.
