Copper tape is a thin strip of copper or another metal together with an adhesive.
This copper strip could be insulated from a conductive element using kapton tape, so we would stick the kapton tape to the surface and on top we would paste our copper tape.
This copper strip allows you to solder cables, components, etc. without any damage.
The RFI/EMI shielding tapes are used as absorption and protection materials for radiating electronic elements.
