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.

These backings are excellent for a movie poster collection. I bought 30 and they fit perfectly into mylar sheets. A must have and will preserve the posters indefinitely.

These backing boards are perfect. I long considered the thicker corrugated boards, but these allow me to store more posters in the box and reduce the overall size and weight. The are a great match with the mylar sleeves. I think these are an excellent product and would buy again in the future.
