|>> the ones from WalMart, the plastic is thin and flimsy
I agree that the Zip-locs I bought from ClearBags were much higher quality than Wal-Mart's (thicker & clearer plastic, more consistent zipper).
However, I like knowing that humidity and oxygen migrate right through thin plastic (slowly). Probably even the high-quality ones leak through the zipper, which I think is a good thing. A tiny amount of humidity can escape and oxygen can get in, very slowly. Seeds are alive and use a tiny bit of oxygen, I believe.
I like plastic better than paper after seeds are fully dry because I live in a rainy, drizzly climate and want to keep seeds viable for as long as possible. A drop of water or a humid day doesn't both seeds inside a layer or two of plastic.
I also like having a verbose label readable inside the Ziploc, where it can't fall off.
Also, I just like gadgets.
I would never store seed that was at all humid in plastic. But I figure that any seed has SOME water left, and my air is prob ably more hu7mid than is ideal for long-term storage. So I keep the Ziplocs inside sealed tubs with dessicant in the tubs but not inside the Ziplocs. After I open and close a tub, the dessicant pulls excess humidity out of the air in the tub, and then the Ziplocs gradually go from "probably dry enough" to "plenty dry".
I'm sure this is overkill, but if I can give my seeds steady 10-20% RH instead of swinging from 30% to 75%, why not? (Actually, I see that Victory Seeds reccomends air Relative Humidity of 30-40%! I may be keeping my seeds TOO dry.)
