Abstract
A method for manufacturing a preservation mat board for use in framing a picture frame. The mat board includes a top facing layer and/or backing layer, each comprising a buffer and/or deacidifying agent, adhered to a middle board or layer by an adhesive containing zeolites. Another embodiment discloses mixing polystyrene pellets with zeolite using an extruder and one or more blowing agents to form a foam material. One or more paper layers comprising a buffer and/or deacidifying agent are heat-fused, without the use of adhesives, to the surface of the foam to form a preservation mat board.
