Why on earth dont you lot do away with those crappy plastic spools that are a continous problem, and just have each reel on a core in a plastic container! The distributors could then easily consider having reels made into 6,000 lengths, even 4k reels would be better than it is now. Pasted from another thread. Last paragraph of Leo's post 05-07-2001.
>If 6,000 foot spools ever do become the norm for distributing release prints, I would much prefer to see them supplied on 4-inch cores packed in tightly-fitting containers (like the ones used for 2,000 foot reels in Europe at the moment, only bigger).<
With the spool problems including wide in structure, Leo's preference might well work. Most cinemas constantly move prints off & onto platters, handling 6,000' on a core should be easy enough. A size of a 2,000' container measures 15". A 6,000' container would only have to measure 23", almost the size of a 5,000' spool.

All color release prints are now on polyester base film stock. AFAIK, none of the major film manufacturers still make any triacetate color print film.Kodak's 35mm triacetate color print film base had a nominal thickness of 0.0056 inches (142 micrometres). Current Kodak ESTAR polyester base (VISION Color Print Film) is nominally 0.0047 inches (119 micrometres) thick. The color print emulsion coated on the base is about 0.0006 inches (15 micrometres) thick. Roll size is a direct proportion to film thickness. So prints on Kodak VISION Color Print Film with ESTAR base will be (0.0047 + 0.0006) / (0.0056 + 0.0006) = 0.85 the roll diameter of triacetate prints. In other words, you can now fit about 15% more film on a reel. ------------------
