CTI: Food-temperature sensitive ink for consumer product labeling

When the temperature is fine, the reminder is ‘off.’ When the package is getting warm, the reminder turns ‘on.’

CTI’s “reveal inks” can be printed on cans, paper labels, cartons, and film and is powered by a combination of thermochromic inks.  When the product, such as milk, is at a safe temperature, the message reads “Drink Milk,” but when the carton reaches a target warm temperature (e.g., 40° F. or 4.4° C.), a color will disappear revealing a “return to fridge” reminder to the consumer.  CTI’s process allows the message, which is enabled to be ‘on’ and ‘off’ throughout the life of the package, to be customized.
