Main functions of Active and Intelligent packaging.

Components of Active packaging	Components of Intelligent/Smart packaging
- Consists of various chemical components that have huge anti-fungal/microbial properties, incorporated in the form of sachets/films.	- Packaging material capable of indicating time temperature for identifying contamination
- Incorporating ethylene scavengers/ethanol emitters/oxygen absorbers in packaging sachets/films	- Food products with sensors/indicators in controlling the micro spoilage.
- Packing contains inbuilt heating or cooling mechanism according to the functions and requirements.	- Shock indicators for identifying physical damage to food products
- Moisture absorbing /carbon dioxide emitters in the form of pads and sheets in food products	- Food packaging sensor that distinguishes between allergen and non-allergen
- Sachets /films made to remove/absorb odor and flavor	- Leakage indicators with microbial growth sensors.
- Contaminants causing food spoilage organisms are controlled in the form of sachets, films, and coating.	- Identification of indicators /sensors for contaminants.
