Under the trusted brand of Archival Methods, our Museum Board 9x12 Polar White 4 Ply PKG 25 is a professional-grade, high-quality product designed for the preservation and presentation of fine prints, precious documents, and both traditional and digital photographs.

The Polar White Museum Board boasts a cool tone with a subtle blue shift, enhancing the visual appeal of your displayed items. It is acid- and lignin-free, incorporating both internal and external alkaline sizing for added protection. This feature safeguards your valuable pieces from the harmful effects of acid migration and environmental pollution that could potentially decrease the pH of the mat board over time.

Our museum board is buffered with 2-3% calcium carbonate, maintaining an alkaline reserve with a pH of 9 +/-0.5. This acid-free composition ensures the longevity of your artwork, preventing degradation and harm to mounted matted artwork.

The 4-Ply, 60 Pt. (Approximately 1/16") thickness of the board offers a sturdy and supportive backing for both display and storage, making it an ideal choice for window mats and mat backing. The color dyes used are light-fast and non-bleeding, preserving the original colors of your artwork.

This museum board passes the rigorous PAT (Photographic Activity Test) ISO IT 18916 (formerly ISO 14523 ANSI IT9.16), and its lignin content, tested by TAPPI 236 cm-85, has a Kappa number of less than five. This ensures the highest archival standards for your valuable pieces.

The single ply sheets of this museum board are laminated together using an all-natural starch adhesive, further enhancing its durability and resistance to wear and tear. With no optical brightening agents used in the pulp or manufacturing process, our Museum Board 9x12 Polar White 4 Ply PKG 25 is a reliable choice for professionals seeking a superior-quality, archival-grade product.
