Time-Temperature Indicators
A Time-Temperature Indicator (TTI) is an intelligent labeling system that visually alerts users if a product has been exposed to temperature and time conditions outside the recommended range during storage or transport. Developed through Nanografi’s R&D infrastructure, TTI solutions are especially critical for temperature-sensitive goods—helping to reduce spoilage risks and enhancing both producer and consumer confidence in quality and safety.
