Copper grounding tape or other grounding methods are usually for "noise" or EMF suppression. It works the same way as a wrist ground strap for static electricity. Errant electrons are routed away from other components so as not to cause interference or damage.
Electronic devices are also regulated as to how much errant EMF/static/noise/electrons not making it to the desired path (however you want to describe it) etc., can be generated and these foils can do just that; "foil" their "escape." (sorry for the pun).
