An acid- and lignin-free buffered cardboard most often sold in light blue or gray colors, but also available in tan and white. Archival corrugated board is typically buffered with 3% Calcium carbonate that provides a pH of 7.5-9.5. A water resistant, modified starch adhesive is used for corrugating. Fluting size is designated by a letter (A-F) that refers to the number of folds per foot.
