A couple of quick questions for our friends that buy and use boxes of TMAX-400 in 100 sheets - Does Kodak divide the contents up in to smaller sealed packs ?
If so, are these packs hermetically sealed ?

Those inner envelopes are sealed until the corners of the sheets of film pierce them. This happens quite regularly. Don't ever buy an open box where the inner envelopes have been exposed to light. You're quite likely to get fogged film. I'm always amazed when sellers show the inner sealed envelopes as though it's a good thing. If the box has only been opened in total darkness, this is obviously not an issue.
Actually, I never put Ilford film in the fridge or freezer for the exact reason you mention. Ilford film in general, as much as I do love it, seems to have more issues with humidity related emulsion problems than Kodak film. Both kinds of packaging have their pros and cons.
If they're zip locked and sealed in containers, why do you put them in the fridge to thaw ? Why not just leave them on the counter ? seem alike a lot of bother jus to warm up film. It's just film. ymmv
Like jnanian, just about all my film is neither frozen or fridged. it's kept in a cool basement fwiw
It's better to slowly change an objects temperature, so many variables to list, but anything can happen in a rushed thaw. If water particles were present it could damage the film not having time for moisture to dissipate, condensation issues from moving the object too quickly to a fil different temp environment. Actual pressure issues from the high difference in temp could lead to the normally capable seal of the container to leak moisture that wouldn't happen with a slower thaw. All sorts of reasons. Plus just the change in temp could effect the emulsion by parts being colder it hotter than others could cause micro-fractures in the emulsion.
I'm probably being overly cautious, but it's good practice to allow proper thaw time. Just like why when you defrost good you should let it sit in the fridge first so that the entire piece can acclimate without cold pockets.
Better safe than sorry.
As well, film is not *that* delicate.
equating food to film is nonsense.
The only reason afaic, to bag film for the freezer is to keep condensation out. If they're zip locked, no probs so toss them on the counter. Film can be shot at any temperature so bringing to room temp is not necessary. As well, film is not *that* delicate.

Well you should have left it in the foil wrapperI've never, NEVER had any issues with film warming up in 120 foil or 35 plastic containers. If you put your film in zip locks that are closed properly, then moisture will not be an issue unless there was moister win the ziplock to begin with.
As for sheet film, my guess would be that if there's enough moisture to cause separation, then the film is most likely pooched anyways from ice crystals forming on the emulsion. but that'd be a wild guess unsupported by any factual evidence.
TMax sheet film ain't that cheap, so if you are rich enough to gamble ruining a package by opening it an hour or two too soon after being frozen, be my guest. Plenty of people have learned that lesson the hard way, as well as how not to put open packages back in the freezer,
If you plan to do a lot of this kind of thing, you can get a nice little vacuum packing device intended for frozen foods for about a hundred bucks.
Yes, 2 packs of 25 in paper packs with metal and plastic inner lining.
... it doesn't come in 100 sheet / box
Those inner envelopes are sealed until the corners of the sheets of film pierce them.
Thanks for confirming that.
Box says "2000" - Compared to some of the plates/film/paper I've got kicking around, that is quite fresh.
