How Archival Is Polaroid 664 Film?

[Matthewt]

I was just curious. If I take photos with 664 film, how long before they fade? Thanks..........Matt

If it's a major issue, consider rephotographing the Polaroid print onto large format film with a copy stand setup. A well processed and stored large format negative will likely last centuries, and if slow film is used is capable of reproducing the 664 print right down to the grain.
