Thermo-sensitive inks change colour when the beverage reaches a certain coolness. What better way to indicate the perfect drinking temperature! In this way the packaging itself helps the brand truly interact with the consumer at the moment of consumption. Inks are UV sensitive allowing for a host of creative design ideas (See our Coloured UV ink product page). Unusual, effective and increasingly popular, this technique is an exciting complement to standard labels. It is available for use on aluminium and white base-coated designs. N.B. 100 day shelf life.
