100ft & 300ft

Why is there a handspool 100ft 35mm film but not a '300ft' 120 ?? or did I miss something and I don't mean those 70mm canisters. Thanks.

Backing paper?

The 100 foot rolls of 35mm film probably wouldn't exist if 35mm film didn't originate as motion picture film.

Backing paper?

No, i don't need 300ft of backing paper just film and about motion film: we have Cinemascope why not 120mm ? greetings

120 film has backing paper. 220 film doesn't.

The standard long roll roll film is 70 mm. What do you want to do that you can't to with 70 mm? Or, for that matter, 65 mm.
