paper tape trays

Polyethelene? Polypropyline? Polyvinyl Chloride? Or some mixture? I am curious because I have a boatload of paper tapes to preserve and protect for posterity. Those DEC tape boxes are nice; they stack and seem to preserve the paper tapes in an available, usable ways. I have also seen a photo of paper tapes on shelves; a whole bank of narrow shelves about 3 inches high, with labels on the shelves. That looked pretty good, if they could be protected from dust. How do you guys manage long-term storage of your paper tape collections? Are there any fatal errors, like would storing them upright for a long time cause a bad enough slump in the paper to prevent readability? Do you keep them out of the sun? What about aftermarket identification labels on the leader, how thick can this become before the tape doesn't work any more? What other problems have you seen?
