Cutting down 70mm film into 120/220 size?

["ROLLAND ELLIOTT (Quality Assurance Co-Op)" <rolland.elliott@xxxxxxxxxxxxxxx>]

 <I......was unaware of this 70mm IR
 <film.  (though I am sure it would be a lot easier if Kodak made 120/220
<rolls).

A different Kodak rep once told me that they don't make IR film in 120/220 size
because the paper backing doesn't shield IR light well, and fogging of the film
would be a problem.  This seems like a weak excuse since Konica is able to
manufacture IR film in 120 size.  Perhaps the extra IR sensitivity of Kodak
films makes the paper backing useless?  Perhaps a aluminum foil backing paper
would be effective in preventing fogging?  I've never used Medium Format gear
so I don't really know if this would be feasible.

Has anybody ever cut down some 70mm IR film from Kodak and used it in a Med.
Format Camera?  If so was fogging a problem and how did you avoid it?

Cheers!
