Packfilm was introduced by Polaroid in the early 1960s as successor to Polaroid rollfilm. This new packfilm was designed to be much easier to use for the consumer. Packfilm was different from rollfilm in that there was no longer a film coating, and that fixer was no longer a necessity.
As you probably guessed from the name, you need packfilm for all Polaroid packfilm cameras. Packfilm camera models are as follows: 100, 200, 300, 400, and the colorpack series.
Unfortunately, this film is no longer in production. Polaroid ceased production of this film type years ago, and we are unable produce new packs as the machinery to produce packfilm would require a big investment.
You can still find some compatible packfilm which was produced by Fujifilm until 2016. Unfortunately, Fujifilm has now also stopped all production of this film format, and only old stock is available. Compatible film formats are: Fujifilm FP-100c (color) or FP-100b and FP-3000b (black & white).
