Archival Fluted Polypropylene – affordable Coroplast alternative

Our natural Archival Fluted Polypropylene Backer is an affordable alternative to Coroplast. Conservators and picture framers use it as a rigid, archival mounting material, and frequently as a backer in picture frames.

SmallCorp’s polypropylene board is an acid-free, neutral pH material with no dyes or additives, like Coroplast. We have it specially made for SmallCorp  in 4mm, 6mm and 8mm thicknesses.  We sell it by the carton in standard dimensions, or we can cut to your specific size.
