Gray board paper — commonly called chipboard or greyboard — is a thick, dense material made primarily from recycled paper fibers. Its exceptional rigidity makes it the structural foundation of rigid boxes, book-style packaging, and any application where firm, non-collapsible construction is required.

Key Advantages

• Outstanding rigidity: High-density compressed construction creates a firm, non-flexible board that holds its shape under pressure
• Made from recycled content: Typically manufactured from 90-100% recycled paper fibers, supporting sustainability goals
• Multiple thickness options: Available from 1mm to 3mm+ caliper for varying structural requirements
• Excellent wrapping substrate: The rigid surface accepts paper wrapping, fabric covering, and lamination with consistent results
• Cost-effective structural material: Provides premium rigidity at a lower cost than solid wood or plastic alternatives

Common Applications

• Luxury rigid boxes: The core structural board inside wrapped gift boxes, jewelry cases, and premium product packaging
• Book-style and clamshell boxes: Hinged and magnetic closure packaging requiring stiff panels
• Packaging inserts: Die-cut structural inserts and product cradles inside presentation boxes
• Hardcover book cases: The rigid core in hardbound book covers and slipcases

Industry insight: Gray board is never the visible surface — it is always wrapped or laminated with a decorative paper, fabric, or printed sheet. Think of it as the skeleton of luxury packaging: invisible but essential. The thickness you choose directly determines how premium the box feels in hand.
