Tetra Pak has designed packaging with an embedded chip that will let you know when your milk has been out of the fridge too long.


The world’s largest packaging giant, Tetra Pak, has created milk cartons that change color when left out of for too long.

The cartons will have an embedded chip that will provide information – such as how long a carton has been outside the fridge, indicate which cow on which farm produced the milk, and other processing and packaging information – on a scannable label.

Working with Aurora, a Brazilian food co-operative, Tetra Pak will target BRIC countries of Brazil, Russia, India and China concerned with sustainability information.
