Smart food packaging combines traditional packaging with intelligent features—such as sensors, freshness indicators, RFID / NFC / QR code tracking, time-/temperature-indicators (TTI), and modified atmosphere packaging—to monitor food quality, trace supply-chain conditions, extend shelf life, and improve safety. These solutions help reduce waste, enhance consumer confidence, support food safety regulations, and enable real-time feedback (e.g. whether the product has been stored properly or is still fresh). Growing concerns around freshness, safety, spoilage, transparent information, and sustainability are driving adoption.
