Pressure sensitive tape 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.
This allows for neater looks and better craftsmanship.
Double-sided tape is created by applying a thin adhesive layer to each side of a carrier material. For example, double-sided tissue tape, an easy-to-rip double-sided tape, is created by applying adhesive to two sides of tissue paper, which is then wound with a siliconed paper to avoid it sticking to itself.
