Have you ever wondered how Kodak film is made? Find out in the Kodak Factory Tour video

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

Making a film is a complicated process that requires equipment, materials and a lot of specialized know-how. Destin Sandlin of Smarter Every Day 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 factory still produces films to this day.

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

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

Once the molten polymer has been strained, it is ready to begin shaping it into transparent film rolls. It passes through a series of temperature controlled rollers which begin to stretch it and as it thins out the speed at which it travels down the production line increases.

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

Once the film is removed from the accumulator, it is scanned to check its quality and then packed in a large wooden box called a coffin. It is then stored until needed to make photographic film elsewhere on site, used for electronics, or sold to an external customer and shipped to another location.

This is just the first part of three videos that Smarter every day will publish the Kodak factory tour. Be sure to subscribe to the channel to find out how clear film is transformed into the photosensitive film we use in some of the best film cameras you can buy.
