I just opened a box of 4x5 film, one that had been opened previously and used a few weeks ago. There were about ten sheets left in the box, and they were all glued to each other. The box had been sitting in the darkroom for a couple of weeks since the last time I opened it. The darkroom is an outbuilding, and so does not have central heat and air, but it stays relatively cool because of the thick concrete floor. I don't know what the humidity is in that building, but there has been some rain recently. I am guessing that humidity caused the sheets to stick together. I had to throw them away.
Luckily I had a new box of film and it's fine. I am storing that now in the house, but the house is not exactly climate-controlled all the time either: I run the AC for an hour or so in the afternoon if it gets unbearably hot and humid.
Does anybody have any ideas about how to prevent this problem when one does not have a perfectly climate-controlled house, and one lives in the humid Southeast? Thanks.
