Specialpapir

Specialpapir is a broad term used in Scandinavian contexts to refer to papers manufactured for specialized uses beyond standard office paper. It encompasses a range of fibers, finishes, and treatments designed to meet specific performance criteria such as durability, chemical resistance, print quality, or structural behavior.

Common categories include archival or acid-free papers for long-term preservation; coated papers for high-resolution inkjet or offset printing; photographic papers; carbonless or security papers; label stock and film-support papers; technical papers such as tracing, filter, or insulation papers; and specialty substrates used in packaging, art, and electronics. Properties often specified include grammage, caliper, brightness, opacity, finish, pH, and tear strength.

Production involves selecting pulp types (wood fiber, recycled, cotton), refining, forming, pressing and drying, with optional coatings or calendering to achieve surface characteristics. Finishes may include gloss, velvet, or matte textures. For many applications, papers are treated for water resistance, flame retardancy, or chemical stability. Ethical and environmental considerations use standards like FSC or PEFC and may pursue chlorine-free processing.

Markets for specialpapir include publishing, packaging, art and design, photography, medical and technical industries. The term also overlaps with "specialty paper" in English, and specific products may be marketed under brand names or technical specifications.
