John's tip about removing the paper backing is solid.
If you have a large changing bag, make a small wire frame from coat hanger wire to insert in the changing bag to give it a "ceiling".

As a former wire service shooter in the days of film, I roll many a roll in a changing bag, while I sure prefer the darkroom, a changing bag works.

Has anyone tried to load stainless steel reels in a changing bag?
