gatorade bottle. medicine bottle (like vitamin I containers). both of these have produced 100% dry paper in all the cases i have seen.

Nalgene bottle. I found one on a summit in Montana that had been placed as a geocache and been in place for nine years. Everything in it was good as new as was the pen for signing the summit log.
