Click image to enlarge

An archivally safe board which can be used for making your own custom sized storage boxes, dividers, heavy weight folders, pamphlet or photographic binders, etc. Acid-free and lignin-free, our non-buffered 1mm board is manufactured for those applications where buffering compounds such as calcium carbonate would cause an undesirable reaction with the materials contacting the board, including natural history specimens. This attractive tan board is lightfast, non-bleeding, and most importantly has no internal polyester barrier which prevents materials from receiving adequate air-flow and intensified, unwanted internal chemical reactions. Package of 25 sheets (polywrapped and cartoned for moisture and handling protection). pH 7-7.5.
