cardb is brown corrugated cardboard made with two flat liners and an inner fluted medium. This familiar construction provides lightweight support at a lower cost than the foam-core options.
The board is cut to the width and height entered, allowing it to be ordered for the project without trimming a larger cardboard sheet.
Choose corrugated cardboard for replaceable posters, temporary displays, shipping support, economical backing, and general projects that do not require acid-free materials.
The fluted center separates the two flat liners and adds stiffness without substantial weight. This product is not identified as acid-free or as a conservation material and should not contact valuable, original, signed, or irreplaceable work.
Learn about economical cardboard backing and when a more protective material may be preferable.
