    The Nikor 4x5 reel is actually adjustable for all pack film sizes, and is pretty much the ideal daylight method for processing it. Hangers really don't cut it, since the film is so floppy, and is smaller than the nominal sheet film sizes. I doubt they would behave well in a Jobo reel either.

    Bits of paper are par for the course when processing it, there's no way to cleanly remove all the glued strip of paper that holds the film to the pull-paper.

    Kodak made a pack film tank, which was round, and took a tray with pie-shaped wedges. You folded a sheet in on itself and slid it into one of the pies. But it's not really a daylight tank, since you have to remove the lid to drain and fill. (It was from the days of Orthochromatic film being the norm, so you used a red safelight.)

    Look out for at least two other potential problems.

    The paper tabs can remain on the film and come loose during processing and stick to the film causing defects, and the film is slightly oversize so that 4x5 is not 4x5, it is longer. This means that you cannot use some holders for this film such as traditional 4x5 hangers. That is why it was often tray processed. Of course the thin support led to buckling in most holders as well which also caused problems.

    Although I know they were used for pack film, in my experience trying to load a Nikor reel with it is very frustrating and leads to many crinkles. The film is just so flimsy. Maybe if I had the experience of an old newspaper lab worker doing many, many a day it would work out. I have two of the "taco" pack film tanks (Kodak and Premo - looks like the only difference is the marking) and while they do have to be opened to drain. it looks like an easier proposition. I have a few more film packs in the freezer so I will probably have it down pat just as I run out of film.
