barkpaper

Barkpaper is a generic term for sheets produced from tree bark fibers rather than wood pulp. It includes traditional handmade papers and modern sheets made from bark fiber alone or in blends. It is distinct from barkcloth, a fabric woven from bark fibers.

Production typically starts with collecting inner bark from suitable trees. The bark is softened, fibers are separated by soaking and beating, and then formed into sheets with moulds or deckles. The sheets are pressed and dried. Some processes mix bark fibers with small amounts of wood pulp or other fibers to adjust strength and texture.

Historically, bark-based papers appear in many cultures. In East Asia, paper mulberry bark (kozo) is used in traditional washi. Indigenous and colonial communities worldwide also produced bark papers for manuscripts, art, and ceremonial uses, often in regions where wood-pulp sources were scarce.

Characteristics vary by species and processing, but bark papers are typically textured and can range from soft and flexible to fairly strong. They may be more sensitive to acids and moisture if not properly finished. Uses include writing and drawing surfaces, bookbinding supports, and crafts.

Economically, bark fiber can be a forestry byproduct or a dedicated crop, offering a lower-energy alternative to long-fiber wood pulp. Sustainable harvesting and careful processing are important to minimize environmental impact. In contemporary craft, barkpaper is valued for texture, color, and historical associations.
