Oftentimes I put exposed film that I will not be able to process for some time back in a can in the fridge. For example, E-6 films or sometimes C-41 films that I like to process when I have 5 or 6 of them to do. I have not noticed any problems. Actually, I have also put them back in the freezer without ill effects. Follow the same recommendations as when opening them fresh. I will add that I normally do keep all of my film packed in ziploc bags. (Hate to get film mixed in with frozen peas!)

Maybe a little "dust-off" spray in the can would be a good idea, IDK. Haven't tried it.
