Keep documents and files protected in our Gaylord Archival® Corrugated Polypropylene Record Storage Carton. It is made from an extruded fluted plastic that is chemically inert and double-walled for extreme durability. The moisture-resistant material is ideal for long-term storage as it will not off-gas. It is also free from all additives, including UV inhibitors, and therefore is not recommended for areas with UV exposure.
