Active and Intelligent Packaging
Packaging systems that actively modify the package environment or indicate product or package condition through absorbers, emitters, antimicrobial components, sensors or indicators.
Active packaging changes the package environment, while intelligent packaging communicates information about condition, history or integrity. Some systems combine both functions.
Oxygen scavengers, moisture absorbers, carbon-dioxide systems and antimicrobial surfaces can target specific deterioration routes. Their capacity must match product, package and shelf life.
Time-temperature indicators, gas indicators and integrity sensors can support monitoring. They measure or infer a selected condition rather than every hazard.
The film, sachet, coating, ink and active substance must be authorised for the intended food and conditions of use. Migration and consumer misuse require assessment.
Test the complete product-package-storage system, including worst-case loading, seal performance and end-of-life conditions. Laboratory response does not automatically predict distribution performance.
Define what the device controls or indicates, how it is interpreted and what action follows. Do not market an indicator as proof of safety beyond its validated function.
