Also, the emulsion could crack from being left in the freezer too long. He added a refrigerator is a wonderful storage place as long as the film goes directly into the camera . There are several issues here. It looks somewhat like the crazing or crackle in a ceramic glaze. The emulsion can't expand as rapidly as the speed of temperature change requires and you get an all over geometric pattern from uneven expansion between the film and its base.
Condensation comes from cold film coming in contact with warm moist air.
If you keep the film sealed in its original packaging any condensation that occurs while the film is warming will be on the outside of the packaging not on the film. If you are really concerned about moisture getting to the film, get yourself one of those vacuum sealing machines they sell for home kitchens and vacuum seal the film in batches of 4-5 rolls. This would also protect the film in a backpack until you are ready to use it. Actually freezing is not an accurate term for what you are doing when you put film in the freezer. Frozen is the term for the solid state of matter and film is already solid so we should say stored below 32 degrees F .
