German auction site there was Fuji FP-100C for sale and the seller
indicated that it had been deepfrozen. I contacted him and he assured
that there would be no difference to unfrozen film. I knew that
Polaroid original film would be ruined by deepfreezing. So we discussed
this on a French Polaroid forum. In the end, nobody had some reliable
information. To know more, we had to test. I froze some colour film and
a swiss member froze some b&w film and some colour film for a
After a week of freezing at -20°C in a Tupperware
style box, two days of thawing at the bottom of the refrigerator, and
one night at room temperature, I unpacked the film pack. Nothing
special to see. I put it in an EE100 camera. No problem with the
black paper dark slide. Then I took a picture, no darken or lighten. No
problem getting the photo out of the camera, no smudges. I waited 100
seconds (it was 20 degrees that winter morning in the south of France).
No difference with a fresh pack, Really none!!!
one problem less since Pack 100 film has been discontinued. It's the
opposite of what has been said, but apparently nobody tried. It only
applies to Fuji FP film, it probably doesn't work with old Polaroid film.
putting in some pictures:

test for the b&w film, frozen for some months, showed no difference
either. The longtime test for colour film showed some slight colour
alterations with the swiss member of the forum. So I made anothe
6-month test. It showed a slight magenta cast after separation of the
photo from the negative. The cast disappeared exposing the photos to
bright daylight for 2 days.
