I have some flakes stored for maybe 5 years now. No issues but I haven't sampled from every bag. I just use up a bag and move to the next. Most recently maybe a month ago when I cracked open a new bag of "super blonde" flakes. The majority of my stash is "super blonde" and "garnet" flakes from Wellermart.

However, I double bag them and toss in a few desiccant packs for good measure in the outer bag. The shellac came in very heavy and heat-sealed bags and I use freezer zip-lock type bags as the second bag. Squeeze out the air for good measure.

I vaguely recall a discussion some time back about using vacuum sealers for this sort of storage. Not tried it and I don't recall if there was any long-term report on effectiveness.
