3M overhead transparencies are perfectly cut into nice A4 rectangles and I 
considered these for a flat plate cap some time back.

PROBLEMS:

1.  These are polyester which is hopeless for RF.

2.  3M is a conservation supportive company and up to 30-50% of the 
material used is recycled, so the sheets may look fine but will have a high 
component of impurity.

I didn't bother going any further :-(

Cheers

Mark
