Pacon PAC5557 White Foam Board 22x28 in Acid-free 5-pack

Product Description

The PACON PAC5557 is a white foam board measuring 22 x 28 inches, constructed from extruded polystyrene foam laminated between two paper sheets. At 3/16 inch thick, it strikes a balance between lightweight handling and structural rigidity. The acid-free surface resists yellowing over time and accepts paints, markers, adhesives, and other common media without bleed-through. Each carton contains 5 boards. This product is used in educational, commercial, and creative settings where a smooth, stable mounting or display surface is needed.

PAC5557 foam board is a standard choice for school projects, craft work, science fair displays, photo and document mounting, framing backings, and point-of-sale exhibits. Its large 22 x 28 inch format accommodates full-size poster layouts and oversized artwork. The acid-free construction makes it appropriate for archival-adjacent applications where longevity matters. Sold as a carton of 5 sheets, it suits classroom environments, print shops, framing studios, and display fabricators who work through material in volume.

Installation Notes

Cut with a sharp utility knife and a straightedge for clean edges; a dull blade will compress the foam core and produce ragged cuts. When mounting prints or documents, use a foam-board-compatible adhesive or mounting film applied evenly to avoid bubbling. Store boards flat in a dry environment to prevent warping. No special tools or trade licensing required for typical display and mounting use.
