Coroplast Archival grade is a chemically inert, extremely durable polypropylene copolymer, extruded twin wall fluted plastic sheet free from additives such as coloring agents, antistatic and ultraviolet inhibitors. Coroplast archival is suitable for backing, mounting, and fabricating containment enclosures. A superior substrate for long-term use with no out-gassing. It is resistant to water, oils, and solvents at room temperatures, and is excellent for making boxes, backing of framed works of art and as a barrier board.
