High-Quality White Duplex Board Paper with Grey Back: Applications and Advantages
White duplex board paper with a grey back is a versatile and durable paperboard widely used across multiple industries, especially in packaging and printing. Known for its smooth white coated surface on one side and sturdy grey backing on the other, this board offers the perfect balance between cost-efficiency and performance. It is a preferred choice for businesses seeking high-quality, high-strength packaging materials that can also deliver visually appealing print results.
What Is White Duplex Board with Grey Back?
White duplex board paper typically consists of two layers. The top layer is coated white, usually with kaolin clay, providing a smooth and printable surface ideal for high-quality graphics, logos, and product information. The reverse side is grey - made from recycled fibers - offering structural support and rigidity at a more economical cost than fully white boards.
Duplex board is manufactured in various thicknesses, generally ranging from 230gsm to 450gsm or more, depending on the packaging strength required.
Main Application Scenarios
Consumer Goods Packaging
White duplex board is widely used for the packaging of consumer goods, such as toys, electronics, and household products. The white surface allows for attractive branding, while the grey back reduces overall material cost.
Food and Beverage Packaging
Although grey back duplex board is not suitable for direct food contact, it is often used in the secondary packaging of dry foods, bottled beverages, and boxed snacks. When laminated or lined with food-safe materials, it can also be adapted for more direct food packaging.
Pharmaceutical Packaging
Due to its excellent printability and dimensional stability, it is frequently used for medicine boxes and over-the-counter product packaging, where clear instructions and professional presentation are crucial.

Clothing, shoes, and accessories brands often use duplex board for folding cartons, offering both protection and a clean, elegant presentation.
Stationery and Office Supplies
From file covers to notebook backing and presentation folders, the grey back duplex board finds broad use in the production of everyday office and school supplies.
Gift and Promotional Packaging
With optional lamination, embossing, foil stamping, and die-cutting, duplex board can be transformed into high-end promotional packaging that stands out on the shelf.
