Bonded leather

Bonded leather, also called reconstituted leather or blended leather, is a term used for a manufactured upholstery material which contains animal hide. It is made as a layered structure of a fiber or paper backer, a pulp made from shredded leather, and a polyurethane coating which is embossed with a leather-like texture. Related products, bicast leather or coated leather, are made by splitting, shaving, or grinding leather to reduce its thickness, and then laminating it.

Bonded leather is made by shredding leather scraps and leather fiber, then mixing it with bonding materials. The mixture is next extruded onto a fiber cloth, or paper backing, and the surface is usually embossed with a leather-like texture or grain. Color and patterning, if any, are a surface treatment that does not penetrate like a dyeing process would. The natural leather fiber content of bonded leather varies. The manufacturing process is somewhat similar to the production of paper.

Lower-quality materials may suffer flaking of the surface material in as little as a few years, while better varieties are considered very durable and retain their pattern and color even during commercial use. Because the composition of bonded leathers and related products varies considerably (and is sometimes a trade secret), it may be difficult to predict how a given product will perform over the course of time. There is a wide range in the longevity of bonded leathers and related products; some better-quality bonded leathers are claimed to be superior in durability over low-quality genuine leather.

Bonded leather can be found in furniture, bookbinding, and various fashion accessories. Products that are commonly constructed with different varieties of bonded leather include book covers, cases and covers for personal electronics, shoe components, textile and accessory linings, portfolios and briefcases, handbags, belts, chairs, and sofas. A more fragile paper-backed bonded leather is typically used to cover books such as diaries and Bibles, and various types of desk accessories. These bonded leathers might contain a smaller proportion of leather than those used in the furniture industry, and have some leather exposed in the product's surface, producing the characteristic odor associated with leather.

These same applications can alternately use artificial leather constructed in a similar appearance to bonded leather.
