after using a roll of film, is it ok to store it in the freezer first before sending a bulk load of them for development?
how long can they be restored in the freezer?

It is in fact advised to keep exposed film cool if you aren't going to develop them right away. And the freezer is even better. Remember - you aren't actually freezing the film. Just making it extremely cold.

I had been told that the fridge is OK, but it's best NOT to put film back in the freezer once the original package has been opened.
The reason is that the film was in a controlled-humidity environment when originally "canned," so freezing a never-opened can is OK.
But once the can (or wrapper) has been opened, normal-humidity air is admitted. If you put the film back into the freezer, even if you put it back in the can first, that humid air is still in there -- meaning there's the risk that the humidity will condense on the film, potentially causing problems such as spots or sticking. (That's also why you're supposed to warm fresh-frozen film back up near room temperature before unwrapping or uncanning it.)
As I say, that's what I was told... but I've never tested it. Another job for the RFF Mythbusters!

Well, if there is some kind of ultra-dry air in the factory, and opening the canister and then refreezing is bad...then I have a lot of bad film. But, as far as I can tell, it's all fine.
