Note that it's on a polyester base. This has presented problems since, unlike acetate, sprocket holes won't tear and the film transport could be damaged.
Well spotted, none of the reputable manufactures sell 35mm films on polyester bases for camera because of the potential damage to the film transport system.
The Ilford special 72ex 35mm had been discontinued by the time some of the current senior management joined the company but they indicated on an APUG factory visit that never again had or would they use a Polyester base for 35mm. It doesn't break, and the sprocket holes don't rip, so the chances of camera damage are potentially very high.

Hello Ian, hello Sal,
I have to disagree. In the past and nowadays several film manufacturers had sold and are selling 35mm on a polyester (PET, ESTAR) base, including Kodak, Agfa, Fuji, Fotokemika Nova (Efke).
For example, Kodak Technical Pan was coated on a polyester base (Kodak called it ESTAR). I have used this film without any problems in my 35mm cameras. And I have never heard, that a Kodak Technical Pan film has damaged the film transport system of a camera.
Maco has offered several films (before they have established the Rollei-Film brand) on a PET base. No problems.
All of the current Filmotec photo films are coated on a PET base. Some of the Rollei-Films, Adox and Bergger films are / has been made by Filmotec. No problems.
The current Agfa-Gevaert films, which are offered by Rollei-Film since 2004, are all coated on a PET base. Never heard of any problems concerning film transport.
I have tested some of these films as well, in different cameras. No problems at all with film transport.
Adox CMS 20 is coated on polyester as well. And the latest batches of Efke films (and therefore Adox as well) are now coated on polyester, too. Look at Mirkos statement in his german Fotoimpex forum.
Back to the topic: If Rollei-Film can offer a 800 speed CN films, I would use it, especially in 120.
Best regards,
Henning
So if you were selling the film you'd be prepared to cover the repair costs for the damage to a camera if caused by the film base ?
It's heavy duty motor drives or over-zealous winding on passed 36 ex that does the damage, but it will happen.
Many of the films you refer to AREN'T designed for normal camera use, many are micro films where the camera is far more robust, others, some maybe cine film, others are re-confectioned films designed for aerial photography or military/industrial applications.
I'm not denigrating the emulsions bt questioning the film base.
Ian
and as far as I know Foma
BUT Kodak, Fuji, Ilford and as far as I know Foma & EFKE DON'T make films designed specifically for film camera use on Polyester film.
