Hello Tim,
I've had problem with exotic films slipping from the reel (plastic in my
case).
From my school days I use a gluing tape made by TESA and called TESA
CREPE it is light brown in color lightly crimped and has a mildly
sticking adhesive and looks globally like the tape used to secure the
120 film on backing paper.
It is used by engineers to stick Mylar or drawing paper on their board,
so you Americans should have something similar. It resist quite well in
water.
when unspooling 120 film, I put a length of this tape at the end of
film. I secure the other end of the tape on the center of the spool and
back to the film if I've enough length. Then I spool the film and
process it. This way, the film can't unspool by itself. You have to be
very careful when unloading the spool with the wet film to reach the
tape which is easy to unglue.
Hope this helps.
