Klebeband

Klebeband, or adhesive tape, is a family of tapes with a pressure-sensitive adhesive on a backing, used to join surfaces without heat or water. The backing is usually a plastic film such as polypropylene or polyester, but can also be paper or cloth. The adhesive is typically acrylic or rubber-based, with silicone formulations used in specialty tapes. Common varieties include transparent office tape, masking tape, double-sided tape, duct tape, electrical tape, and gaffer tape.

Properties vary with the backing and adhesive combination and are described by tack, peel strength, shear strength, and temperature resistance. These factors determine suitability for tasks such as sealing packages, mounting, labeling, or insulating electrical cables. Some tapes are waterproof, while others offer UV resistance or transparency.

Manufacture involves coating the chosen backing with an adhesive layer, and, for some products, applying a removable release liner. Production lines may include extrusion, coating, and slitting to standard widths.

Uses span households, offices, packaging, crafts, and industrial settings. Packaging tape is widely used for sealing cartons; masking tape is common in painting; electrical tape provides insulation for electrical work.

History notes that pressure-sensitive tapes emerged in the 20th century, with early consumer cellophane tape popularized by 3M in the 1930s. The term Klebeband is standard in German-speaking areas to denote this class of products.

Environmental considerations include disposal and recycling challenges due to mixed materials, though some tapes are formulated for easier removal and reduced residue. Safety concerns are generally minimal, but certain adhesives can irritate sensitive skin.
