Ageless Eye Oxygen Indicators

These indicators enable to detect visually whether the bag is oxygen free.

It turns from blue to pink when there is no more oxygen. 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 bag, 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.
