problem with long stored neg

[nze]

Hello all

I make some film development for another photographer. He gave me hundreds films to develop and in this film there are some long stored film ( about 2 years old). They appear to have some mark on them. I don't know what's up because I develop them with fresh exposed film and don't get the mark on the fresh one

what format film ?

Is important as it might be 120 and problems with the backing paper & humidity

Good point Ian. I was thinking of heat or reticulation too.

Yes looks like texture from paper backing.

My guess, humidity.
