1. Overview of Duplex Board Paper

Duplex board paper is a form of paperboard consisting of two layers, typically with a coated surface, widely favored in the packaging and printing industries. The dual-layer structure provides enhanced strength, printability, and versatility for diverse applications. Duplex board, especially coated duplex board (CDB), is classified into various types such as coated duplex board grey back, coated duplex board with grey back, duplex board grey back, and duplex board white back according to its surface and reverse-side finishing.

8. Professional FAQ: Duplex Board Paper Key Terms

1. What is the structure of duplex board paper?

Duplex board paper consists of two layers: a high-brightness, coated surface facing for printing, and a stiffer reverse side (grey, white, or brown), forming a strong, smooth composite sheet.

2. How is the GSM (grammage) selected for protective packaging?

The required GSM depends on product weight and required rigidity; for heavy-duty packaging, 350-450gsm is recommended, while 230-300gsm suffices for lightweight boxes.

3. What coating types are available for coated duplex board?

Light-weight coating (LWC) offers a lighter, semi-gloss print finish, while high-weight coating (HWC) provides a thicker, smoother surface for high-quality or moisture-sensitive applications.

4. Are duplex boards suitable for direct food contact?

Only boards tested to relevant food safety standards (like FDA/EU) and with low Cobb value are suitable for direct food contact. Always consult the supplier's technical sheet for food-grade certification.

5. What standard sizes are available?

Common sizes include 1092x787mm, 1194x889mm, 610x860mm, 31x43", and custom sizes can be manufactured for special requirements.

6. How does duplex board grey back differ from white back or brown back?

Grey back is economical, suitable for inner surfaces; white back offers premium look (higher print whiteness on both sides), and brown back combines cost advantage with natural appearance and strength.

7. What is the recommended storage and handling procedure?

Store boards in dry, clean rooms away from humidity. Handle with care to prevent edge damage or surface contamination before printing.
