I have two boxes of Ilfochrome paper released just before the discontinuation was announced; 1 x 12"x16", and 1 x 8"x10" unopened. I also have an opened box of 8"x10" paper. The unopened materials have been stored in a cool, dry place but not at under 10ºC. The Ilfochrome data sheet http://www.ilford.com/media/53862/cps_clm.pdf suggests allowing paper to warm to room temperature before opening, however I've often been nervous of storing paper in a fridge due to concerns over condensation and moisture; as the paper is not completely sealed in the box.
If I were to refrigerate the paper as I'm most likely not going to use it in the next few weeks are there any extra precautions worth taking, e.g. Ziplock bags etc?
