Die cut storage boxes made from CXD Premier Grade Grey/White Archive Board which is made to a detailed specification designed to give a safe storage environment for all types of archive material including photographs. The board is low in reducible sulphur and other oxidising elements, free from optical brightening agents, and is laminated with a specially produced pH 7 plasticiser free EVA adhesive. Lightfast, 5 to 6 on the blue wool scale, the paper is buffered with calcium carbonate and has an average pH value of 7.5 to 8.5. These boxes are unique because the board for each box is specially laminated prior to the die cutting process, when the board is still damp which prevents it from cracking.
