I've noticed that any plant/vegetable matter will have a tendency to rot if it's in direct contact with plastic.
I store seed in 2" x 3" manila coin envelopes, which then are grouped in ZipLoc bags. I store them refrigerated, but dry. This is only to prevent further drying and deterioration of the seed. It does not affect the "dormancy" or sprout inhibition the seed may have. If you're planting seed outside in the late fall, no stratification is needed, winter will do it for you. No refrigerator storage is really necessary either, but you will need to purposefully protect the seed beds or pots from all manner of critter damage, from above and below.
About six weeks before expected planting time, I put a half inch of water in the baggies to moisten the envelopes, then, after 20 minutes or so, drain off the excess and put them back in the refrigerator. This six week period of cold, wet storage simulates winter, and is intended to break any "dormancy" or germination inhibition the seed may have. A percentage of seed will sprout with no stratification, but since it doesn't hurt to stratify all of the seed, I do, and it keeps germination more or less uniform. I don't pay any attention to the bags of seed until six weeks have passed. This is a very hands-off, efficient way to process seed.
To give you an idea of what you can get away with, this March I put about a dozen 2016 seed in wet storage in the refrigerator. When I looked at them yesterday, they all had "roots" about 1/8" long, so I planted them outside in pots. There were no floaters or squishers. They grow very slowly under refrigeration and will live a long time, as long as they aren't touching plastic. I've had seeds go over six months in wet, refrigerated storage and by then they'll have roots and blanched leaves up to 2" long. They really need to be babied at this point, if they are to survive exposure to light and low humidity, because they're too soft for the real world, and the energy stores within the seed have been used up. A percentage always seems to pull through though. At some point during long wet storage, the paper envelopes will start to lose integrity, and they'll get a little moldy, but the seeds and sprouts inside are clean,healthy and ready to go. One or two seed in each envelope may rot, but that's an inevitability, and it doesn't seem to affect the healthy ones. My favorite time to plant them is when they have a small root and a leaf about 1/2" long, as it provides a good handle to hold them by. When planting, I cover the seed with about 1/8" of mix, or enough so that the seed is still covered after misting .
I've never tried peroxide, but one year I moistened the seed envelopes with a Physan 20 solution and the paper envelopes looked very clean after months in wet refrigerated storage. It didn't seem to affect the seedling mortality, as I still found the occasional bad seed in the envelopes, but the envelopes were a lot cleaner and nicer looking. I don't use fungicides when sprouting seeds because mortality a necessary part of the selection process.
. Now just 100 more to go 
. I am so excited. Thanks for all the help, I am sure I would have lost all of them, with yall. :thankyou
