Sorry about the name.
I have never used the smaller size, only the "4x5" and I restricted my answer to what I know about that format, so size and pack design may have been limited to the larger product. The packs for the Kodak holder were made in a variety of sheet film sizes, but I have no idea when they were discontinued. My last use of them was in about 1962, but that has nothing to do with the actual date in which packs were stopped being produced.
Sorry I was not clear. All other answers above and my generic comments still apply such as buckling and the paper/glue adhering to the film during processing.
