Good idea. A flexible conductive epoxy of the type supplied by the regular adhesive
suppliers (who are probably going to be looking at bendy versions of their die attach
products) is worth a go provided you can get a cure schedule which is compatible
with the flex circuit material  (and not effect adhesion of the foil), but may not be the
best/sole option. For example how are you going to maintain your outline when laminating
this stuff into the middle of a flex circuit, if uncured, or get adhesion if cured on one
layer? Assuming I read you right.
So it might be a good idea to try also suppliers of inks and things for flex circuits, I
think Acheson is a leader here. They anyway will be uptospeed on what can can't be done
and how to.
There are companies that specialise in RF shielding products, problem is I am not familiar
with your market place.
Finally when all else fails they say  RTFM [read the manual]. In this case a Nepcon West
Show Catalogue. This should give you classified lists of companies in the unlikely event
that Technet strikes out (if that's the correct phrase).

Best of luck
Mike
