The new beverage cans from Ball Packaging Europe change colour like a chameleon - shifting, say, from blue to purple or yellow to green with a change in temperature. Previously, the colour could only be made to change from white to blue. By enhancing the thermochromic ink technology, Ball has opened up new opportunities for customers to design cans with striking colour effects. For the first time, Ball has made thermochromic ink not only change colour from white to blue, but from any colour to any other. The secret of thermochromic ink is held in special microcapsules. The colour change is triggered when the can reaches a specific temperature.
