Use Gaylord Archival® 40 x 60" B-flute Corrugated Board (25-Pack) to back frames, makes boxes, line shelves and create supports for artifacts. It is made from two outside sheets of archival paper and a fluted inner sheet. Because of their arched design, the flutes resist bending and pressure and serve as insulation to moderate temperature and humidity inside the enclosure. The larger flute profile increases vertical compression strength and acts as a cushion.
