Corrugated Board:
University Products Multi-Use Bi-Corr Cross Direction Perma/Dur board "For ultimate strength and rigidity in archival board, we offer Bi-Corr Cross Direction Perma/Dur Corrugated board. As the name suggests we laminate two layers of our very best corrugated board together so the corrugation of each runs perpendicular to the other. The result is a lightweight board of exceptional strength which resists bending, folding or curling. This blue/gray board, with its 0.25" thickness, is exceptional for picture frame backing but is equally effective as a sturdy display construction material. In fact, it excels in any application which requires a strong but lightweight acid-free material. A 3% calcium carbonate buffer offers additional protection from atmospheric pollutants. Like both our single and double wall corrugated boards, this board is made of bleached cellulose fibers and is acid-free and lignin-free. Sold in full cartons of 8 sheets. Price per carton." [1]
