Duplex board is a multi-layered paperboard featuring a white coated top surface and a gray or brown recycled back. This construction balances print quality on the visible face with cost efficiency from the recycled inner and back layers, making it one of the most popular packaging substrates worldwide.

Key Advantages

• Cost-effective print quality: The white coated top surface delivers good color reproduction at a lower price point than solid bleached board
• Balanced construction: Recycled gray back layers reduce material cost while the white face maintains visual quality
• Good structural strength: Multi-layer construction provides adequate stiffness for folding cartons and product packaging
• Wide availability: One of the most commonly stocked packaging boards globally, ensuring reliable supply and competitive pricing
• Recyclable: Accepted in standard paper recycling streams despite the multi-layer construction

Common Applications

• Standard folding cartons: Food, beverage, pharmaceutical, and household product packaging
• Cereal and food boxes: High-volume consumer packaging where cost per unit is critical
• Rigid box structures: Inner structural board where the gray back is hidden by wrapping paper
• Point-of-sale displays: Counter displays and shelf talkers where only one side faces the customer

Industry insight: Duplex board is the pragmatic choice when your packaging has a clear front-facing orientation. The white printable surface handles customer-facing graphics while the gray back stays hidden inside the box or against the shelf. For packaging where both sides are visible, upgrade to SBS.
