Jerry said polyester film as "a loop of film and some brushes could make a van-de-graff generator".That idea would work with older films, but KODAK VISION Color Print film has a thin transparent conductive coating on the back side of the film that quicky dissipates any static charge by providing a path to ground. Prints stay much cleaner because they don't attract and hold dirt with static charge, and annoying "shocks" when winding prints are much less likely. Some ad trailers are printed on different stock, and the difference in dirt level, shedding and static is quite noticeable. ------------------ John P.

Matthew asked: " What use would you have for scrap film other than recycling?"In the theatre, old trailers certainly should be used for training new operators in proper splicing and handling techniques. A loop of a trailer having very dark scenes should be run several hundred times after any lamphouse changes, to verify that the projector is not causing heat damage. Trailers can be used as thread-up and protective leader, but be sure the picture and sound do not get shown to the audience accidently. The gelatin emulsion can be removed from the film by soaking the unwound film overnight in dilute hypochlorite laundry bleach, then rinsing and drying. Hard to do with long lengths, but a way to make "clear leader" for shorter lengths. The polyester plastic used for print film base is essentially the same material used for plastic beverage containers (PETE), so it can be recycled into new plastic. Film can also be used as an environmental fuel for power plants, or recycled into leader: Link to Kodak Film Salvage Link to Kodak Environmental FPC, Inc., a Kodak subsidiary, has been honored by the Academy of Motion Pictures Arts and Sciences with an Award of Commendation.
The award honors FPC for developing and implementing an environmentally responsible program to recycle or destroy discarded motion picture prints. Since it was founded in 1952, FPC has destroyed or recycled more than 330 million pounds of motion picture prints. Film is shipped to the FPC plant in Tennessee, where it is recycled into leader or burned as a replacement for fossil fuels. ------------------ John P.
