Hot or Not?

Although it is difficult to define exactly what smart packaging, is, one significant component of any smart package is its ability to communicate with the person interacting with it. In food packaging, some packages can communicate freshness, while others can communicate a product's history or expiration. In terms of the pharmaceutical market, packages integrating RFID tags to verify authenticity is another example. Other smart packages combine communication with functionality, like self-cooling beer kegs or self-heating soups and coffees.
