I'm not as advanced nor knowledgeable as some members here in terms of long food stroage, but because of the high humidity here in Florida, vacuum seal my dry stores...I double seal the seams, and then place the package in a fairly opaque 5gal bucket...it does waste a lot of space conpared with using a mylar bag and oxygen absorbers for an entire bucket of one item...

the dried milk I've stored is not a regular use item rotated like some other supplies, so decided to repackage it from its original waxed paper box container....

if the stores are not needed in 3 years, then they have given me peace of mind, and were worth the cost

I do rotate regular used stores, especially mindful during hurricane season
