Hensaplenty : My thoughts on that subject are this. If the dried seeds have too high of a moisture level still in them, and you put them into a plastic bag and seal them up, the risk of something like "damp rotting" might take over and destroy them. Again, I have no scientific data to back up this thought, but I always tend to err on the safe side. I usually put my seeds onto an uncoated paper plate for initial drying and that is done in my homemade seed dryer. When they first come out of the homemade dryer, they go into coin envelopes for a few weeks and this allows them to continue releasing moisture as they stabilize with the ambient humidity.

I don't permanently store any seeds in plastic baggies. My final storing container is some repurposed prescription bottles. If medicines do well in these bottles, then my seeds should also do well.

If I were to have to choose between plastic or paper as the only thing I could ever use, I would always go with the paper.
