Our B-flute, 5/8″ thick corrugated boards are both sturdy and lightweight, features which make them suitable for a wide variety of conservation uses. The paper is the same used in the corresponding solid fiber board we offer. Lig-Free I corrugated is tan on both sides and buffered throughout. MicroChamber/ Silversafe corrugated is a tan buffered sheet on one side and a neutral pH, white paper on the other. Details on our various papers are found under the Technical Information tab on this site. Prices shown are per sheet with minimums of ten sheets. Large sheets will have to ship by truck, but can often be cut down for UPS or FedEx upon request.
