Elmer's is fine as far as acidity and long-term performance are concerned. It wouldn't be used where it might have to be removed in the future (although it can be removed easily).
A steam iron won't scorch or harm paper, as long as it's steaming. It might polish the surface, so it would be better to work from the back side, with the cardboard face down on several thicknesses of clean paper.
If you don't have any acid-free paper I could mail you a piece. But since it's on the back and never seen, almost anything will do.
