Kleefpapier

Kleefpapier, or adhesive paper, is a type of paper that carries an adhesive coating enabling it to stick to surfaces without separate glue. It includes self-adhesive papers, label sheets, and sticker papers. The adhesive can be permanent, removable, or repositionable, and may be pressure-sensitive or moisture-activated.

In construction and formats, the adhesive is usually applied to a base stock such as paper or film and protected by a release liner until use. When ready to apply, the liner is removed and the adhesive bonds to the target surface. Common formats include label sheets designed for printers (laser or inkjet), sticker sheets, and laminated labels. Variants may use water-activated gummed adhesives or dry, pressure-sensitive adhesives.

Applications span labeling, packaging, and branding in commercial settings, as well as office, home, and school use for organization. In crafts and arts, kleefpapier serves decorative purposes, scrapbooking, and DIY projects. Industrial uses include asset labeling, barcode tagging, and safety signage.

Materials and performance vary by purpose. Base stocks range from standard coated papers to transparent films, with finishes from matte to glossy. Adhesives can be acrylic, rubber, or hybrid formulations, chosen for permanence, surface compatibility, and resistance to factors like temperature and humidity. Some kleefpapier is designed for easy removal with minimal residue, while other varieties provide strong, durable bonds.

Environmental considerations focus on recyclability and the impact of the adhesive backing. The combination of adhesive and backing can complicate recycling streams, prompting development of more recyclable label stock and less environmentally burdensome adhesives.

Historically, self-adhesive papers and label stock became commercially important in the 20th century, enabling widespread labeling, branding, and decorative applications.
