giordano Posted January 4, 2012 Share #2 Posted January 4, 2012 Put the cans, with unbroken seals, into another hermetically sealed container and put that in the freezer. Google will find you more info, including this from Kodak. Link to post Share on other sites More sharing options...
cbretteville Posted January 5, 2012 Author Share #3 Posted January 5, 2012 Thanks John, A fellow Norwegian Leica enthusiast recommended ZipVac bags. So I have ordered some. Like the idea of removing as much air as I can from the bulk rolls. Carl Link to post Share on other sites More sharing options...
budrichard Posted January 6, 2012 Share #4 Posted January 6, 2012 Any sturdy ZIP LOCK freezer type will work. The main concern is that you allow the film to thoroughly come back to normal room temperature before loading or using.-Dick Link to post Share on other sites More sharing options...
tobey bilek Posted January 6, 2012 Share #5 Posted January 6, 2012 You want a sealed container so "self defrosting" freezers do not dry the film. Better still, stay away from self defrosters. Wrap the film is a comforter or between two pillows or a single roll in you pocket. In all cases, keep sealed until room temp is achieved. I have been freezing film 40 years + and the problem has never occurred with me. Link to post Share on other sites More sharing options...

I have been freezing film 40 years + and the problem has never occurred with me. No problems with me either. I just put them in the freezer in the box they came in. When I get them out, I first put them in the fridge and let them defrost there. Then I keep the one I need in my trousers- pocket until they are warm enough to unpack out of their container. ( Mostly in 10 minutes. ) Link to post Share on other sites More sharing options...

Some plastics (google LPDE) are gas permeable, just as plastic bottles can be (typically not LPDE). The later is one reason to store chemicals in non-permeable plastic.

earleygallery Posted January 7, 2012 Share #10 Posted January 7, 2012 Not bulk, but ive always just put unopened film in the freezer, 35mm in it's container and 120 foil wrapped. Never had any issues. Link to post Share on other sites More sharing options...

In the link I posted, Kodak specifically warn that "a small amount of vapor leakage through the closure of a taped can is unavoidable" and recommend that the sealed cans be stored in a vapour-sealed outer container if they're going to be kept for longer than a month.

Thanks. I was thinking in terms of the plastic 35mm containers and foil wrapped 120. I guess with the bulk rolls they might be opened up and in and out of the freezer until finished. Didn't consider that before! Link to post Share on other sites More sharing options...

If I was going to freeze those long term I'd search the Kodak site for advice on whether a second hermetic seal was necessary. For those thinking in terms of freezing a lifetime supply, remember that low temperature doesn't give any protection from radiation. Consider building a lead-lined room for the freezer.
