A common grade of paper commonly used for letterhead, business forms, writing, typing, and copying. Bond papers are characterized by high permanence and durability, high surface strength to withstand writing and erasing, and high stiffness. Unwatermarked bond papers, made from chemical pulp, are used for invoices and other business forms. An air-dried, watermarked, cockle finish bond is used for high-quality letterhead. The highest quality bond papers are cotton-content bond papers, which are produced from a higher amount of rag-based pulp (from 25:100% cotton-fiber). High cotton-content bond papers are used for distinctive letterheads and writing papers, as well as matching envelopes.
