Chuck forwarded a message from another source about long term storage of his favorite Duos:
I don't follow this list, but I agree with Dan if you want a vapor proof bag, you need a metalized bag, polypropolyne and most other flexable plastics, absorb water and outgas both into the air and the bag. Vacuum sealing with the right bag, desiccant and a VCI inhibitor would do the trick.
Wow! if it was true that most flexible plastics absorbed water and outgassed it into the air, I'd be able to work such magic in my job that I'd be a hero overnight. Unfortunately, there are only one or two plastics I know of that will absorb moisture and they aren't available as flexible materials yet. They're also incredibly expensive in comparison to most plastics in use as packages.
Polypropylene is a much better barrier than polyethylene, but it's not very common to see PP in a clear bag. Usually you'll find it as metalized PP. Vacuum sealing isn't a requirement. If you can vacuum seal the bag you'll require less desiccant or VCI but as long as the bag is sealed to prevent any outside moisture from leaking in (other than through the bag material itself) you only need to add enough extra desiccant / VCI to handle the additional volume of air.
Anyway, I think you have the general idea. If you're able to find some military surplus metal boxes/drums that fit your Duos, you'll get even better moisture protection than from any bag you can buy. Otherwise look for bags with a foil or metalized layer, as there are smaller gaps between the metal molecules than between plastic molecules.
