4. Manufacturing Process
Pulping: Recycled paper is pulped into uniform fibers, mixed with sizing agents for water resistance.
Forming: Fibers are layered on a Fourdrinier machine to create plies, with the core layer optimized for stiffness.
Lamination: Plies are bonded using heat (120–150°C) and pressure (5–10 MPa) via hydraulic presses, ensuring interlayer adhesion .
Finishing: Surfaces are calendered for smoothness, and optional coatings (e.g., UV varnish) are applied for enhanced durability.
Cutting: Precision slitting or die-cutting to meet custom dimensions (e.g., 600x600 mm to 1200x1200 mm) .
5. Quality Assurance
Stiffness Testing: Conducted using ISO 2493-1:2010 (15° bending angle, 50mm span) or TAPPI T 489 (Taber tester) .
Adhesion Strength: Evaluated via peel tests to ensure ply cohesion under stress.
Environmental Compliance:
FSC/PEFC certification for sustainable sourcing .
Low VOC emissions from adhesives (e.g., 3M™ 5 Green Chloroprene Adhesive) .
Compliance with EU REACH and US EPA standards.
6. Industry Standards & Certifications
Material Standards: ISO 9001 (Quality Management), ISO 14001 (Environmental Management).
Performance Standards:
ISO 5628 (Four-point bending test for thick boards) .
TAPPI T 566 (Flexibility testing for thin variants).
Sustainability:
100% recyclable and biodegradable.
FSC-certified mills ensure traceable, deforestation-free raw materials .
7. Market Trends
Sustainability-Driven Demand: Growing preference for eco-friendly packaging in e-commerce and luxury sectors .
Lightweight Solutions: Thinner variants (e.g., 1.0mm) gaining traction for cost-effective, yet rigid, applications.
Technological Advancements:
Automated die-cutting for complex shapes.
Nanocoatings to enhance water resistance without compromising recyclability.
8. Key Considerations for Buyers
Moisture Control: Store in dry environments (RH ≤60%) to prevent warping.
Print Compatibility: Ensure surface smoothness meets lithographic or digital printing requirements.
Customization: Suppliers offering embossing, foil stamping, or die-cutting add value for premium packaging .
Supplier Evaluation: Prioritize vendors with ISO 9001 certification and proven track records in high-stiffness board production.
