The Importance of Shielded Cables - Tech Resources

Foil shielding incorporates a thin sheet of either copper or aluminum. This "foil" is usually bonded to a polyester carrier to enhance the strength of the cable. Also known as "tape" shielding, this type of shielded cable provides protection for the conductor wire they are wrapped around. No EMI from the environment can penetrate.
