Product Overview
China's Duplex Board Grey is a two-ply paperboard engineered for optimal performance. The top layer features a smooth, coated white surface (100–400 GSM) for high-definition printing, while the recycled grey core (80–200 GSM) provides structural rigidity. With a total thickness of 200–500 GSM and machine-direction (MD) stiffness of 3.0–27.0 MN·m, it balances aesthetics and durability.
China's Duplex Board Grey Key Features
1. Exceptional Printability
Surface Quality: Coated with premium pigments (e.g., kaolin), the top layer achieves a roughness of ≤2.0 μm and brightness ≥82%, ensuring sharp offset, flexographic, or digital printing for vibrant branding and intricate designs.
Color Accuracy: Supports 4-color process printing with high ink absorption, ideal for luxury packaging (e.g., smartphone boxes for renowned brands) and retail displays.
2. Structural Integrity
Tensile Strength: ≥2.5 kN/m, resisting bending and tearing during transportation and handling.
Moisture Resistance: Cobb value ≤50 g/m² for the top layer and MVTR ≤20 g/m²/24h, protecting contents in humid environments.
3. Sustainability
Recycled Content: Contains 70–90% post-consumer waste paper, reducing reliance on virgin pulp.
Certifications: FSC®-certified options available, aligning with global eco-friendly sourcing standards. The company also adheres to ISO 9001 (quality) and ISO 14001 (environmental) management systems.
