Details

Museum Grade Archival 100% alpha-cellulose board, buffered with a 3% calcium carbonate buffer. It is acid-free (alkaline pH 8.0-9.0), lignin-free, contaminant-free. Suitable for conservation. Our material meets the Library of Congress Archival Standards. Acid-free board can trap migrating acids in paper and neutralize it. A buffered board can stop migrating acids from entering an object and therefore prevent damage.
