The strange part is the fact that with film - light is more translucent with a polyester base and less so thru the acetate base. Anyone have any ideas, or guesses why? No one has been able to answer this yet!! It is a very strange phenomenon. I still think that it has to do with the tapepack, but I could be wrong.

They're right. You can also tell the difference by pulling on it until it
breaks; the acetate snaps off cleanly while the polyester stretches first.
