Abstract
A novel flexible package for an oxygen reference solution has been developed. This package is made from a laminated film including preferably polypropylene as the inner layer, aluminum foil as the middle layer, and polyester as the outer layer. The seams are heat sealed, while an optional access device for allowing access to the solution after the storage period, is attached to the inside wall of the bag without breeching the middle barrier layer.
