Progress in controlled release for active packaging

Active packaging is a new package technology which uses packaging material as the carrier and releases the preservatives such as antibacterial agents and antioxidant agents to preserve the food quality and extend the shelf life. In this study,the progress of the research on the release- active packaging with the antibacterial and antioxidant properties was reviewed.Firstly a general introduction was given to kinetics of release.Then the four ways of releasing control including resin composition,multilayer composition,nano material composition,and encapsulation were introduced in detail. Finally,the future trends and prospects in the development of active packaging were highlighted.
