unholyroller Pillar of the Community United States 1903 Posts	Posted 01/07/2012 10:47 pm I vacuum pack a lot of meats and other foodstuffs and one company I know of sells vacuum sealer bags made of Mylar anywhere from sandwich bag size up to ones you could put a body in.....not that I want to vacuum seal a body...lol. Just thought I would mention it for anyone wanting to store bulk quantities of coin and not worry about tarnish and PVC damage. The bags a super strong too. Just Google Mylar vacuum seal bags and you will see. Report this Post to the Staff

If I really crank an impulse sealer, I can get a seal on real thin mylar, but even 2mil is almost impossible. Mix the two parts of epoxy glue in large quantities and submerse the entire bag into this. Allow to completely dry. Makes no difference how thick the Mylar is then. Aquire those cans of liquid plastic used to decopage and emerse the entire bag in that. Might be possible to seal with a Butane Torch. I use Zip Lock Plastic bags for all my Albums and just push out as much air as possible and run my fingers along the seal and it's good enough for me. Report this Post to the Staff
BuffaloBonehead Valued Member United States 333 Posts	Posted 01/08/2012 4:28 pm I use the snorkel vac for mylar sealing. I have trouble with it when I overpack or use too thick of a mylar bag, but it isn't something that I can't fix by cutting it open and trying to seal it again. Report this Post to the Staff
Earle42 Bedrock of the Community United States 10038 Posts	Posted 01/08/2012 4:44 pm For my ziplocks - the el cheapo alternative to an actual vacuum sealing system:: 1. Insert coin/album/proof sets. 2. Seal most of the way while squeezing out air. 3. Insert drinking straw deep along one side. 4. Create continual vacuum while pulling straw out. 5. As straw reaches top, quickly seal remaining strip of bag. - cheap, fast, no electricity, and works - but also teaches that after awhile ziplocks - even the double lock ones - will lose a vacuum.

CelticKnot Bedrock of the Community United States 12822 Posts	Posted 01/08/2012 5:23 pm I bought a bunch of dimes earlier this year and they came to me sealed in what looks like a food-grade vacuum bag. Seems like a pretty good idea for storage of your 90%, especially if your climate is humid. However I didn't consider the possible tarnishing depending on composition of the bag. There's nothing on the bag that would help me identify it and research its composition, so perhaps I'll swap that out. But again, it's just 90% dimes, so I don't really care all that much.
