3mm Grey High Thickness Eco friendly Book Binding Board For Notebook Covers/Grey Chip Board

Grey Chip Board: Core Characteristics

1. Structural Durability
Grey chipboard typically features elevated thickness (0.8-3.0mm) and high-density composition, delivering exceptional compressive strength (≥8kg crush resistance) to withstand stacking pressures in logistics.
2. Engineered Rigidity
With bending stiffness of 15-25 N·m/g (ISO 5628), it maintains dimensional stability (±0.15% warp tolerance) under load, preventing deformation in applications requiring shape retention.
3. Enhanced Printability
The controlled surface roughness (PPS ≤3.0μm) enables uniform ink absorption (dot gain <15%), supporting high-fidelity offset/UV printing for branding and information marking.
4. Eco-Conscious Composition
Manufactured with ≥70% recycled pulp (FSC Mix certified), it achieves 90% biodegradation within 180 days (OECD 301B), aligning with circular economy principles.
5. Cost Efficiency
Offering 40% lower cost per m² vs. solid bleached board, it provides optimal price-performance for mass production without compromising structural integrity.
6. Processing Adaptability
Compatible with:
High-speed die-cutting (±0.1mm tolerance @12k sheets/hour)
Precision creasing (180° folds >100 cycles)
Automated gluing (adhesion strength ≥4.0 N/mm)
for streamlined packaging and craft production.
7. Cross-Industry Versatility
Proven functionality as:
Publishing: pH-neutral (7.5-8.5) hardcover book boards
Packaging: Reinforced gift box shells (ECT ≥14 kN/m)
Display: Warp-resistant exhibition panels
Industrial: Laser-cut architectural models
