"I store quite a lot of my posters in plan chests, and don't put anything between the posters. Any damaged ones, or with old tape stains I store else where. I think these posters have lasted 50 years of abuse until I got them, I'm sure they will out last me.
The worst is cardboard, and poster tubes they are full of poster munching Acids, yet I have bought posters that were stored in these and they seen fine."
I think Paul is dead on with these comments. I have said for years (which earns me the anger of bag and mylar manufacturers everywhere!) that the climate and conditions where you store the items is far more important that what you store the items in. The very best condition paper collectibles finds were made in Canada and Colorado, and yet all those items were stored completely unprotected for decades. But both were in natural cold environments. By contrast, posters found in Central America and the Middle East are almost always in dreadful condition. Coincidence? I think not!
I think you can store your items unprotected (and save a fortune!), as long as where you store them is controlled as to temperature and humidity (and you don't want zero humidity). You also want no or little light on them. Most important of all, there must be protection from insects and vermin (such as mice).
Get this set-up going, and you will find that your collection shows next-to no sign of age (and as Paul says, even items stored poorly, like in tubes or in bags and boards, don't seem to age under these conditions).
