I'll second that. I think Elmer's is a casein glue that works well only
on porous substances, like wood. If the sheet doesn't come with an adhesive backing, use a waterproof glue that doesn't require a solvent to evaporate. [It won't, through mylar.]

BTW, there's a huge difference between aluminized mylar (99% of it) and silvered mylar. It is the metal that counts, not the mylar substrate. The price may give you a clue. The silver tarnishes quickly if not sealed, so that product is much, much more expensive to make, for a 10-12% increase in reflectivity. Look for at least 95% guaranteed.
