Just found this you tube video in a post on facebook by "Film is not dead"

Show (In the light) the manufacture of the IMPOSIBLE project SX-70 style cartridges, including the actual coating of the negative film, similar to the process for almost all current film production I would guess.
Hello Charles,
yes, the coating of the negative film base is indeed very similar to the process for non-instant photographic films.
The coating of this negative film base for the Impossible films is done by InovisCoat in Monheim, Germany:

They are also involved in the research of the new Impossible films.
This company is run by former Agfa Leverkusen engineers. And most of their machinery is also modernised machinery from the former Agfa film plant in Leverkusen, Germany.
InovisCoat also cooperates with other classic film photography companies.
Best regards,
Henning
