Single-Sided Tape, also known as Single-Coated Tape or Single-Faced Tape, is a pressure-sensitive tape consisting of film, foam, foil, cloth or paper face stock with rubber, acrylic or silicone adhesive on one side, and either has a silicone release liner or is self-wound. Adhesive tape refers to any one of a variety of combinations of a backing materials coated with an adhesive. Different backing materials and adhesives can be used depending on the intended use. Double-sided tape is any pressure-sensitive tape that is coated with adhesive on both sides. It is designed to stick two surfaces together, often in a way which is not visible in the end product, due to it being in between the objects rather than overlaying them.
