The Benefits of (B&W) Polyester Film – By Emanuel Hentes

It has (much) better archival qualities. That’s it. That’s why it’s so great. The rest of the article just expands on that idea.

I am implicitly assuming you agree that being concerned about the archival quality, longevity, permanence, lifespan (or however else you might call it) of film is something worthwhile – at least to some extent. I initially wanted to argue why I think that one should care about the permanence of film, but I soon realized this endeavor would get highly philosophical and would detract from the overall purpose of the article. The issue of why would be worth its own separate article. Nevertheless, I think I’m making a fairly safe assumption.
