Premium Duplex Board: White Back & Grey Back - Beyond Ordinary Packaging
Engineered for Performance, Designed for Tomorrow
In the evolving landscape of sustainable materials, duplex board emerges not just as packaging but as precision-engineered substrate technology. With White Back (bright, print-ready surface) and Grey Back (robust, cost-effective core) variants offered in 0.3mm, 1mm, 2mm, and 3mm, we deliver solutions merging ultra-precision with structural intelligence. Forget generic boards-ours integrate nano-calibrated layering for unmatched flatness and ink adhesion, setting new benchmarks in functional design.
Breakthrough Applications: Where Science Meets Surface
Harnessing thickness as a functional variable:
| Thickness | White Back Applications | Grey Back Applications | Innovation Spotlight |
|---|---|---|---|
| 0.3mm | Ultra-light luxury tags, QR code sleeves | Medical device sterile barriers | Thinnest FDA-compliant food-grade layer ↓30% material use |
| 1mm | Fragrance tester cartons, micro-perf samples | Pharma blister pack backing | Silicon-valley approved "smart-pack" base for NFC tags |
| 2mm | Vegan cosmetic compacts, foldable POP displays | Automotive part protective trays | Anti-static coating-ready for electronics |
| 3mm | Carbon-neutral watch cases, museum archival boxes | Heavy equipment shock-absorbent corners | Load-bearing >18kg despite paper origin |
Why Engineers & Designers Choose This Duplex Board
Precision-Calibrated Rigidity
Each micron is optimized: 0.3mm achieves flexible crispness, while 3mm rivals wood-based boards at 1/3 the weight.
Circular-Economy DNA
100% recyclable with closed-loop processing-verified 0.48kg CO2e/sqm footprint (EPD-certified).
Surface Intelligence
White Back: 98% ISO brightness with ceramic-coated barrier against oil/grease.
Grey Back: Cross-directional tensile strength >7kN/m for palletized loads.
Grey Back: The Unseen Structural Genius
While White Back shines visually, Grey Back operates as the hidden structural engine in:
Robotic warehouse shelf dividers (2mm)
Shock-diffusing e-bike battery casings (3mm)
Vaccine cold-chain insulated liners (1mm)
White Back: The Aesthetic Innovator
Redefining print performance:
Achieves 97% Pantone color match accuracy-unheard of in recycled board
Holds 200LPI+ stochastic screening for hyper-detailed cosmetics imagery
Certified for direct food contact (ISEGA, FDA) in pastry sleeves (0.3mm)
Reimagine Packaging Physics
From featherlight 0.3mm smart labels to indestructible 3mm industrial crates-this isn't cardboard. It's precision-engineered fiber technology where every layer serves a calculated purpose.
"The right thickness isn't a specification-it's a strategic tool."
