Art Paper vs. SBS Board: Structural and Coating Differences

Understanding Coated Art Paper

Art paper is a high-grade paper treated on one or both sides with a mineral coating (kaolin clay or calcium carbonate). This coating prevents ink absorption into paper fibers, locking pigment on the surface for exceptional image sharpness and vibrant contrast.

Primary Applications: High-end magazines, visual product catalogs, brochures, and photo books.

Understanding SBS (Solid Bleached Sulfate) Board

SBS board is a premium paperboard manufactured entirely from virgin bleached chemical wood pulp. It features a coated top surface for printing and an ultra-clean white reverse side, offering high tear resistance and superior stiffness.

Primary Applications: Cosmetics packaging, pharmaceutical cartons, luxury retail boxes, and heavy pocket folders.

Key Architectural Differences

• Fiber Structure: SBS features multi-ply construction engineered for structural rigidity and clean score/crease lines without cracking.
• Bulk & Caliper: SBS delivers significantly higher thickness per unit weight compared to standard multi-coated art paper.
