Along with branding and attracting consumers, packaging is now using color for functional aspects.
The largest packaging manufacturer, Tetra Pak, has created milk cartons that change color when left out of the fridge for too long.
The cartons have an embedded chip that provides information about provenance and packaging and is aimed for use in BRIC countries to develop the notion of sustainability.
Ball Packaging has developed aluminium cans with thermochromic inks where temperature changes give rise to color changes.

This clever tool expresses when the contents are at the optimum temperature. Similarly, Scientists at the University of Strathclyde in Glasgow have developed smart palstic that can indicate if the food packaged in it is spoiled or not. The new material would be cheaper than currently used labeling, making it a viable solution for future food packaging.
