Copper tape refers to an adhesive-backed copper tape. Copper tape can be found at most hardware and gardening stores and sometimes electronic stores. Copper tape is used to keep slugs and snails out of certain areas in gardens, potted plants, and trunks of fruit trees, and other trees and shrubs. It is also used for other applications, such as electromagnetic shielding or low-profile surface mount transmission line in electronics and in the production of tiffany lamps. It comes in two forms; conductive adhesive and non-conductive adhesive (which is more common).
