Love your insert but it's very far from industrial facilities! This mashines is to coate "some" holographic plates on glass say a couple of it during a week!
A plant have many so called around equipment too! Not just a table!
Well, certainly not comparable to Kodak facilities, the professional device I mentioned, is capable of coating glass plates of 1 x 1m size and PET (polyester) film up to 1000m length (3280 ft) at 30cm width.
My point is that specialized products can be manufactured to exacting standards by small companies. Whether the manufacture of photographic products could be economically viable, I don't know. As Ron points out, there are lots of film and paper sizes. Again, not easy, but possible with good engineering.
