Ah, but 0.6mm is more than enough....but to be sure you should 
measure it with a depth-gauge (Dutch: schuifmaatje (onderzijde)).
Thin polyester foil (0.1mm) exists in #87, thick polyester foil
(0.4mm) in #87C. 

I am currently also doing some research on a thin #89B for the same
application, but then of course for Konica, Ilford and Agfa. I have
at least one solution, but it requires a rather large minimum order,
so this is only feasible if I can get a bunch of filters cut in
exactly the same size....and fitting more than one brand/model of 
camera....my EOS-1 measures an exact 24.0mm height
between the filmrails (width is not crucial, I point at 45mm). 

So a question for those having a depth-gauge at hand: would this 
24.0mm fit other brands & models of cameras?

PS: don't poke that depth-gauge through your shutter....pick the 
sides of the frame rails, not the middle....;-))
