If you shoot film, chances are you know a little bit about how it works and how it’s developed – but you might not know about how it’s made. The latest video (below) from Smarter Every Day on YouTube takes you on a tour around the Kodak factory in Rochester, New York, and shows you the process from start to finish. 

Manufacturing film is a complicated process that demands specialist equipment, materials and a lot of know-how. Smarter Every Day's Destin Sandlin is an engineer and producer, who was recently invited on a behind-the-scenes tour of the Kodak Factory in downtown New York. It was founded in 1890 by George Eastman and, despite filing for bankruptcy in 2012, the plant is still producing film to this day.

Most 35mm film produced at Kodak is made from polyethylene terephthalate pellets (PET) which is the most common thermoplastic polymer resin in the polyester family. To start the process, these pellets are ground down to a fine powder so that it takes up more surface area and can easily have a stabilizer added to it. 

The powder mixture is then passed through giant metal “screws” where it is melted down by friction, passed through a vacuum to extract unwanted gasses, and then exits the screw as molten polymer.

Once the molten polymer has been filtered, it’s ready to start shaping it into clear rolls of film. It’s passed through a series of temperature-controlled rollers that start to stretch it out and as it gets thinner, the speed at which it moves across the production line increases.

Different coatings are precisely added to the material as it travels along the production line, and these coatings can help the photosensitive layer bind better, give it an antistatic layer or even a conductive / gelatine coating depending on the final use of the film.

Once the film is taken off the accumulator, it is scanned for quality and then packaged in a large wooden box known as a casket. It's then stored until it’s needed to make photographic film somewhere else on site, used for electronics or sold to an external customer and shipped to a different location.

This is just part one of three videos that Smarter Every Day (opens in new tab) will be posting of the Kodak factory tour.
