I posted this thread about issues with my Mamiya RB67 Pro-S film back advance not functioning properly because it would continue without locking or fail to register an exposure. Someone mentioned that there is a thread out there about slippery 120 backing paper. I didn't find it.

Have you had any trouble with Kodak Gold 120 film slipping in a medium format camera film back?
 
I don't believe the frame counter mechanism on an RB67 insert is controlled by a wheel and friction against the backing paper.
 
The RZ uses a rubberized roller to meter the film, I'm not sure about the RB. Many systems did.

It's usually the old rubber hardening rather than the backing paper that causes slippage, along with increased friction in the gears due to old lubrication.

The frame counter is driven by a roller on the photographer's left side (supply side) of the roll film holder. The design of this roller varies somewhat between Pro and Pro S backs - on the Pro backs the entire length of the roller turns, on the Pro S it's just a little wheel at the top. There is some discussion in this thread:

However the specific issue in that thread that motivated superglue, is running 35mm in a RB67 back and getting the narrow film to turn the counter. Not an issue of the film counter wheel slipping on full-width 120 film. I might have been thinking of that thread and misremembered the topic.
