“Innovative Oxygen Absorption Packaging Solutions” was the title of an informative presentation from Atsushi Inoue, R&D Manager at Mitsubishi Gas Chemical Co.
The company has developed a special iron-based oxygen absorbing resin that does not need moisture or activation sequences to absorb oxygen. Moisture and odor absorption can be also be added for this multi-function packaging solution.
It will compete with sachets, which consumers may not like in their pharmaceutical packaging. Stability studies using the OxyVanish absorber in plastic bottles were tested with EPA supplements, vs EVOH (ethylene vinyl alcohol) barrier and HDPE (high-density polyethylene). The absorber kept the product fresher and with less “fish-oil” smell than the other two constructions, for up to a year.
Testing of the absorber is also underway for food applications.
