My apologies for the belated reply here; I haven’t been reading very deeply into the site lately…!
One of the suppliers of dehydrated (powdered) eggs

Once Opened, How Long Will Powdered Eggs Last?
Stored in the absence of oxygen and placed in a cool storage environment, powdered eggs have a storage life of 5 to 10 years. Once a container of powdered eggs has been opened, it is comparable to any other dehydrated dairy product and shelf-life would be measured in weeks or a month. Many people opt to refrigerate the remaining portion or only open as small a container as possible. If the goal is to keep the remaining powdered eggs long-term, we recommend that you re-pack the remaining portion in a smaller container with an oxygen absorber. Keep in mind that the eggs will only store as well as the condition of the original product - and therefore, should be free of moisture and oxygen.
In other words, I think, best packaging is the original, if it is foil packs or plastic-lined tightly sealed bags, stored in colder-is-better (your freezer?). If otherwise packed in bulk (buckets?), you will need to repackage into smaller mylar bags with oxygen-absorbing packs, heat sealed (use your iron) and otherwise vacuum sealed – or maybe use one of those vacuum-sealing gizmos on late-nite TV? Since a little can go a long way in an average household, smaller packs are a good idea to ensure freshness if using over a longer period. Most of what is sold in bulk these days is intended for volume users – bakeries, etc – who might be expected to consume a full bucket in only a day or two.
A bit of investigation about
exactly how the original is packed is time well spent, I think. And learning how to repack stuff is highly useful info. Lots of websites offer good advice there. Some good points here:
