Coated duplex board with grey back

The front side of the coated duplex board with grey back presents a soft grayish-white tone with precise grayscale control,while the backside core is a uniform dark gray with a rough texture, enhancingthe paper's adhesion performance and compatibility with any paper lamination needs. It meetsthe color and stiffness requirements in packaging design, with structuralstability sufficient to meet the mechanical performance demands of mostpackaging scenarios, performing stably during regular stacking andtransportation.

This product is made from 100%post-consumer waste paper pulp, achieving resource recycling at the rawmaterial stage, reducingwood consumption by about 70% and water usage by 50% compared totraditional virgin pulp paper, deeply aligning with the EU CEFLEX initiativeand domestic 'dual carbon' policy orientation, providing core material supportfor a green supply chain system.

The coating surfacedemonstrates excellent compatibility in print adaptability, providing goodmatching for halftone reproduction in offset printing, color saturation inflexographic printing, line clarity in gravure printing, and surface gloss inUV printing. The surface smoothness is controlled between 200-300 seconds (Bekkmethod), ensuring that the color reproduction rate exceeds 90% during 4-6 coloroverprinting, meeting the printing needs of intricate patterns and textinformation. The gray backside is more suitable for lamination on variousmaterials such as paper and fabric and so on.

The weight covers a full rangeof specifications including 230gsm, 250gsm, 300gsm, 350gsm, 400gsm, and 450gsm,where 230-300g is suitable for lightweight packaging such as cosmetic innerliners and electronic accessory hangtags, while 350-450g meets thehigh-strength needs for heavy-duty corrugated box face paper and appliancecushioning pads, providing flexible choices for diverse packaging designs.

With its comprehensiveperformance, it is widely used in single-layer folding paper boxes (for food,daily necessities, etc.), corrugated composite cartons (e-commerce logisticspackaging), supermarket promotional cards, clothing hangtags, among other fields,providing stable material solutions for fast-moving consumer goods packagingand industrial product identification.

This product has passed FSC Recycled 100% forestcertification (ensuring 100%post-consumer waste paper source), EUDR easier traceability, DDS EU due diligenceand other regulatory certifications (complying with cross-border tradeenvironmental standards), SGS physical property testing (including burststrength, fold endurance, and 16 other indicators) and MSDS chemical safetydata sheet filing, possessing international competitiveness in qualitytraceability and safety compliance. In terms of cost control, it has a 15-20%price advantage over similar coated white cardboard, although its surface glossis slightly inferior to coated products, its environmental attributes andmultifunctional adaptability form a comprehensive value, making it an optimalhigh-performance-to-price ratio packaging material solution.
