EA10
These indicators enable to detect visually whether a package is oxygen free.
They start off pink in colour but when opened and inserted into the package they will turn blue. Once the package has been sealed and the oxygen removed, the tablet will turn back to pink when oxygen concentration is below 1%.
It is thus easy to check if the heat seal was correctly performed, or if the pouch contains enough absorbing sachets compared to its volume.
Extracted from the package, the indicator turns back to blue and can be used again.
The indicators shelf life is limited in time, in its packaging it cannot exceed six months.
