I think that freezing, thawing, then refreezing film several times is ok. But if it is not in sealed containers you run the risk of introducing ice into the film from the condensation during the thawing cycle.Originally Posted by Diapositivo
I suspect the plastic sealed envelopes that major film brands use for 120 film are a good moisture barrier. And I suspect the plastic 35mm canisters are adequate.
Can anyone give definitive advice about sheet film and film wrapped in paper?
