Certainly someone knowledgeable will come up with a good answer. While we're waiting, here's my lame, never-tried-this answer!

The problem is that film has layers. Both the film back and the emulsion are creased (I assume). If you manage to flatten the backing, the fragile emulsion will likely crack. Unless you can soften the emulsion layer. Soaking the film may soften the emulsion and allow it to flex as you flatten out the film base. Or it may completely destroy the image.

I think I would try to get the best possible print from it by putting it in a glass carrier in the enlarger. If you stop down the enlarger lens, you might increase the depth of focus enough to cover the crease. Once you have the best print possible, then try soaking it in Photo-flo or equivalent. To hold it flat while it is drying, maybe you could carefully sandwich the edges (sprocket holes) between wooden craft sticks (tongue depressors).

Doing a project with very old family photos.  I have a strip of 35mm negative that on it says safety ILM 3 I think it is, but that isn't the biggest problem.  It was over the years creased like paper that had been folded.  Some of the folds are through the middle of the image.  Any way to flatten.

I have no idea what is one them.  Judging from the prints found with it, I would wager a best guess of about 50 years. They don't appear to be scratched up.

First idea is to contact print them with glass on top to see what I have.  I could probably copy them from a contact print, but would rather have the wet print if possible.  Would leaving them sandwiched between two plates of glass with some weight on top do any good.  Though about soaking them, but thought better of that pretty quickly.  Might or might not help.  Ideas and thanks everyone
