Can you help me identify this film?

[uranylcation]

Bought a film back online and found a roll already loaded with the arrow lined up. But the backing paper is not routed correctly, so likely it’s not exposed. I rolled it back to find no identification markings. Any ideas what it could be? Anyway, I plan to shoot at ISO100 and develop in HC-110 or Rodinal, what could possibly go wrong, right?

Obviously this is no evidence, that it is Fomapan 100, but I do know, that Fomapan uses this nondescript backing paper. I also know, that not many films use such nondescript backing paper.

Wish you best luck exposing and developing this thing ...

Thanks. I'll find out this weekend

Ilford uses that type of backing paper.

Load the film onto a reel and put it in the tank, turn on the lights and check the backing paper to see what film it is.

Yep, Delta 3200 has that backing paper too (or at least it did when I last used it a couple of years ago.) Good luck, OP!

I had a similar problem a few years ago. I loaded the film on a reel, closed the tank and then looked at the paper from one end to the other. The beginning of the paper told me that it was Rollei film. I suggest that you try the same thing and then examine to length of the paper. Also you could cut a little film off the end, develop it so you can look at the imprint in the rebate area.

In these modern times, when minimum order quantities are so high from the remaining backing paper supplier(s), and 120 film sales volumes are so low, backing papers look very similar to each other.

This is Ilford paper, you can roll the film onto an empty spool, then see the specific film on the exposed label. After that, just roll it back onto the original spool, making sure to keep tension on the film as you roll it up so you don’t get a kink.

I cannot find a supplier of backing paper to save my like, and I’ve asked everywhere I can think of. You would think the 120 width film would be the hardest thing to get for MF bulk rolling, it’s not lol. But this is definitely Ilford. Foma/rollei would have writing saying it’s 120, Kodak and Fuji would be… well, Kodak and Fuji, and Shanghai uses similar paper to Fuji. Only edge case I can think of is that maybe it could be CineStill or CatLabs, but it’s much more likely to be Ilford.

Looks like a roll of Arista Edu 125, which these days is Foma but in the past was Ilford.

Whatever it is the chances are it's ASA 125 or so and can be developed with Ilford's FP4 instructions (or Foma's, if you are so inclined).

A few years ago Harman/Ilford were quite forthcoming about the details of backing paper availability, in the context of exploring whether it made economic sense to bring back 220 film production.
And of course Kodak went through the wrapper offset debacle when their huge inventory of self-produced backing paper finally dried up, years after the near collapse of the still film industry forced them to dismantle their backing paper manufacturing capacity - a debacle that nearly caused them to cease 120 film production.
There are very few paper manufacturers and printers out there that have the capacity to make the narrow tolerance, high specification paper necessary for top line film production, and their lead times are long and minimum order quantities are huge - which in turn imposes a large capital burden on the film manufacturers.

This makes sense. And I figured this was the case, hence why Ive asked film manufacturers about buying from them. Kodak and fuji didn’t respond (go figure), Ilford and Foma told me no at least, and Reflx says that they’ll roll my film in new paper (assuming with Shanghai) but won’t sell paper directly. Astrum says they can cut me backing paper, however as mentioned the tolerances are small, so it might not work correctly, and Astrum does have a minimum $1000 USD order. Seems my best bet might just be to get in contact with a lab and ask if they save intact paper and spools and send me a big box, although Ive had some trouble with that as most labs seem to tear through the backing paper in some way when unloading the film.

Well, turns out it's Delta 100, and it developed fine. $60 for a GX680 film back is not a bad deal, the bonus film makes it even sweeter

If the lab is unloading 120 film manually for processing, then the backing paper should be intact.
Maybe they are not "gentle" enough.
