most of what happens to film happens thanks to fogging by gamma rays. Gamma rays don't notice your fridge, in fact they don't notice the earth, and pass right through it, just as easily as your fridge.
BrianShaw, I will try summarize..
Film or paper should be stored in environment with 40 % to 60 % relative humidity (RH).
RH below 30 % might result temporarily brittleness and lead to unacceptable curl and possible emulsion cracking.
RH above 65 % can damage containers (e.g. rust), cause labels, tapes and cartons to deteriorate and encourage the growth of fungi.
Manufacturers recommend a maximum temperature of 13 ◦C for longer periods.
Manufacturers' expiration dates can be extended by storing at still lower temperatures.
25 ◦C is OK If storing for less than a month.
Infrared-sensitive films shall be stored at −18 ◦C at all times.
There is a table with temp specs for various materials and a few notes under it, the relevant one is:
For VERY LONG STORAGE of all types of photographic materials, the recommended storage temperature shall be between −18 ◦C and −20 ◦C.
Further within the ISO 18928 doc, there is storage room specs on gases, extraneous radiations, background radiation, mechanical requirements, medical x-ray film stuff, airport stuff about carry-on baggage, the well known ISO 400 barrier.
A table with temperature acclimatization for various films and paper.
Bibliography refers to SO 18906, ISO 18911, ISO 18918, ISO 18920 and some books and tech reports
And.. some other stuff

I do it two ways. I put my 100' roll in the bulk loader and load as many cassettes as I think I'll need for a couple of months. The bulk loader goes in a freezer bag, I get as much air out as I can and put the loader in the freezer. When it's time to load more cassettes, I lit the loader sit out overnight before opening the bag.
The other way is to take the partly used 100' roll out of the loader, but it in a metal 100' can (I have several), tape the lid joint and put that in the freezer.
I've been doing this for more than 50 years and have never had film go bad, either color or black & white.
I think the whole gamma ray thing is over blown. My freezer is in the basement, so it is shielded by earth, the house, metal, etc. Don't seem to hurt my film.
Hmmm. I have one of those "seal a meal" gadgets which evacuates much of the air and then heat seals the bag. I'll bet that would be a good way to prepare a bulk loader for the freezer! Just don't confuse it with the rib roast nearby!
