Considering that there are negatives around from the 20s and 30's in box/folding cameras that are still good, I'm going to call bullshit on this. Those films were invariably NOT stored in ideal environments and the film base is still fine. The *emulsion* may have gone bad, but that isn't the fault of the base.

In order to make acetate archival grade,

however at room temperature it's lifetime is decades.
Triacetate film is also sensitive to humidity and water.

Whereas glass, paper, and polyester can all be stored at room temperature for centuries.

Polyester will always outlive the binder and color.
Also you can store polyester film in your library,
where albums and other records belong.

I don't know anyone that keeps a dry fridge in their library.
And the fridge in my kitchen is too humid,
mold grows in food left too long,
as with most kitchen fridges.

In terms of the camera winding mechanism,
it can be repaired, even reinforced.

If polyester film is so much cheaper, then Ilford should make some.
Hey perhaps can even "innovate" and make some vegan film, with gum arabic binder.
Then I and other healthy young people expecting to live a long time, would have reason to buy your film.

Otherwise Rollei knows where it's at with polyester! Woo hoo :-D
They are often sold out, even in online stores.
Obviously other people know its benefits also.
Gonna have to order direct from Germany.
