- 100% Cotton fiber pulp (99% Alpha Cellulose). It does not contain any post consumer waste recycled pulp. Paper is free of metal particles, waxes, plasticizers and residual bleach peroxide. Sulfur content is less than 0.0008% reducible sulfur. Iron content does not exceed 150ppm and copper does not exceed 6ppm. No optical brightening agents are used in the pulp.
- Alkaline sizing is used for both internal and external sizing. No alum is used in the manufacturing process.

- Color dyes are light-fast and non-bleeding.
- Board will not degrade and cause harm to mounted matted artwork.
- Board passes the PAT (Photographic Activity Test) ISO 14523 (formerly ANSI IT9.16).
- Lignin content is tested by TAPPI 236 cm-85 and has a Kappa number of less than five.
- The single ply sheets are laminated together using all natural starch adhesive.
- Note: Some suppliers of archival products are providing confusing information about the use of un-buffered boards and papers with photographic materials. Black-white and color photography (both conventional and digital output) should have mounts or enclosures made from buffered paper. This is the recommendation from the latest ISO document 18902, “Photographic Films, Papers Filing Enclosures”. The only items that need matting or storage in un-buffered papers are cyanotypes (architectural blue prints) and protein based textiles. ISO18902 is available at www.ansi.org,
