Core Features
Superior Print Performance
90%+ D65 brightness (top side) and 85%+ back side whiteness ensure vivid color reproduction and sharp image clarity.
High surface smoothness (≥100 ISO 5627) and gloss (≥45 ISO 8254) reduce ink consumption while enabling high-speed 6/8-color offset printing, digital printing, and decorative finishes (hot stamping, UV coating, laminating).
Excellent ink absorbency and low surface roughness (≤1.40 μm PPS) guarantee consistent print quality even at 18,000 sheets/hour

production speeds.
Structural Excellence
Basis weight range: 170–400 gsm (customizable up to 1800 gsm via lamination) with tight tolerance (±3% per ISO 536).
Exceptional stiffness (CD: ≥1.08 m·nm, MD: ≥1.98 m·nm) and internal bond strength (≥130 J/m²) support die-cutting, folding, and box forming without warping or cracking.
Low moisture content (6.0–7.0% ISO 287) ensures dimensional stability and long-term storability in non-direct sunlight environments.
Sustainable & Safe
Made from FSC-certified virgin pulp (no recycled waste paper) and free of orthophthalic substances, fluorescent whitening agents, and harmful additives.
Recyclable and eco-friendly, aligning with global demands for sustainable packaging solutions-a key driver of market growth.
