Applying Microelectronics to Food Packaging

Intelligent packaging is engineered to sense change in the environment within or external to the contents in a package—or on the package structure itself—and to respond by signaling the change. Among the intelligent packaging technologies that have been proposed, developed, or even introduced in recent years have been time-temperature integrators, maximum temperature indicators, radio frequency identification (RFID), tracking systems, interactive information generators, microbiologic…
