Seems odd to purge with nitrogen then vacuum seal. Isn't nitrogen a
desiccant? It would be pretty easy to buy or build a glove box and put your
standard thermal sealer inside. Hook up to the nitrogen line, and away you
go.
I have seen die and caps stored for years in a nitrogen purged dry cabinet
that bonded/soldered beautifully.
