When I started collecting 16mm film, I found a site by Paul Ivester that describes various film stocks and markings, there is also a section on VS and other "enemies" of film.
Film Preservation Basics
At the bottom of the tab to identifying film stocks, you will find this: quote: A non-destructive method to tell Polyester (Estar, etc.) from Acetate
One technique is to use crossed polarizers, such as camera filters or 3-D glasses. Overlap the polarizers, and orient them so that they are opaque. Place the film between them. If it is acetate, it will appear opaque. If it is polyester (Estar, etc.) it will depolarize the light, and the area of the film will appear less opaque.
Here is a link to the "Guide to Identifying Color Movie Film Stocks" on the site, it includes many pictures:
