Industry Overview & Application Trends

Duplex board paper is recognized for its smooth double-faced surface, enabling both-side printing and superior print fidelity. Typically composed of bleached (white) and unbleached (grey) pulps, this material ensures balance between strength, brightness, and print adaptability.

• Packaging & Carton Manufacturing: Used for boxes in pharmaceuticals, foods, toys, electronics due to its rigidity and printable surfaces.
• Photo & Poster Printing: The rise of both side printing photo paper for marketing and creative industries.
• Stationery & Offset Printing: Preferred for brochures, calendars, notebooks, and premium double sided printer papers.

Technical Parameters & Product Comparison

Fine-tuned technical parameters distinguish each duplex board paper grade. Below is a comparison of mainstream products—standard duplex board, coated duplex board grey back, duplex board with whiteback, and double sided printer paper.
