IML Color Change with temperature control range: above 45°C and below 25°C

In the video demonstration, IML products change color rapidly when exposed to hot water above 45°C, revealing clear and vibrant patterns; they also change color in cold water below 25°C. This dual temperature-responsive color-changing effect not only enhances the fun and recognizability of the packaging but also provides functional indications, such as optimal drinking temperature reminders or temperature status displays. This technology not only elevates the premium feel of the product but also serves practical purposes, such as safety temperature alerts and best flavor timing indications.
