Wikipedia suggests it might be Mylar (i.e., polyethylene terephthalate).
I still don't know how to make it disolve though. So far we've tried:
- Acetone
- Hexane
- Butyle acetate
We don't have any other really cheap solvents in our lab...
Oh well, I guess I could try using mineral acid to disolve the iron
coating. :-S
