Backings

Our PAPERBACK, DIGEST AND PULP BACKINGS are not meant to be used as backings with paperbacks and pulps, but for packaging thinner items if corresponding sleeves are being used.

We stock 3 grades of backing boards:
1. CHIPBOARD - pH neutral board contains acid but is .030" thick and an excellent choice for short-term storage. White on one side. SUPER economical.
2. STANDARD ACID-FREE is acid-free all the way through. Acid-free board can trap migrating acids in paper and neutralize it. Use our .028" thick board for intermediate to long-term storage. White on both sides.
3. SUPER ACID-FREE - Our .040" thick board is off-white, 100% alpha cellulose board and buffered with calcium carbonate, which keeps the board from breaking down (indefinitely). Acid-free (alkaline 8.0-9.0), lignin-free, contaminant-free. Suitable for conservation. Meets Library of Congress Archival Standards for indefinite storage.

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.
