Packaging

A
class of packaging that can
detect the temperature, pH,
etc either the packaged food
or the food environment inside
the package is called Intelligent
food packaging. A package can
be intelligent if it has the ability
to track the product, sense the
environment inside or outside the
package, and communicate with
human. For example, an intelligent INTELLIGENT FOOD PACKAGING IS AN INNOVATIVE
