Finally, no more sniffing the milk to see if it’s turned.

Bemis and ThinFilm have teamed up to develop intelligent packaging for food, which will be able to monitor environmental experiences.

The labels will be powered by printed batteries to ensure they stay charged during the foods' shelf life. Although at first there will only be one sensor to record temperature, the plan is to create a platform to which other sensors can be attached. This means the labels will be able to get more and more advance, be applied to many different types of foods, and prevent people from food poisoning due to dodgy storage conditions.

"Intelligent packaging is an emerging technology with many potential intersections with Bemis' flexible packaging and pressure sensitive materials business segments," said Henry Theisen, Bemis company president and CEO.

FilmThin was the first company to commercialise printed rewritable technology. Its partnership with flexible food package supplier Bermis will see the labels starting to appear in food packages in 2014.
