This is a common bit of confusion.

Mylar is a sheet form of polyester.  Polyester is not a 
low-surface-energy plastic and is not suitable as a release film.  There 
are Mylar products with surface treatments to minimize surface energy, 
but these are specialty films.  If you buy generic Mylar from, say, an 
art store, you might end up with a sheet of Mylar securely bonded to 
your project.

Some release films sold are almost indistinguishable from Mylar to most 
of us.  So if you want release film, don't ask for Mylar.  Ask for 
release film and buy it from a place that sells epoxies and related 
materials.
