Tissue tape, also known as double-sided tape or adhesive transfer tape, is a type of tape that consists of a thin, flexible backing material coated with adhesive on both sides. The adhesive is typically a pressure-sensitive adhesive (PSA) that allows it to adhere to various surfaces upon application of pressure. Tissue tapes are commonly used for bonding lightweight materials such as paper, cardboard, plastics, and fabrics. They are often used in applications where a strong, permanent bond is required between two surfaces without the bulkiness of traditional adhesive tapes.
