You will need to find these used, but they are around. However, 3 pyrex meatloaf pans will work just fine. If you are worried about having enough to process or scratching your neg, you can always do one at a time using the brush method.
My experience with all Polaroid, peel apart films is that when frozen the chemicals crystalize rendering them useless.

Refrigeration is fine but freezing is not recommended. I believe I got the info years ago from Ansel's Polaroid Photography book.

You might want to test a sheet of two of your stash.
