What is duplex board?
If you work in the packaging industry, you may have heard the term ‘Duplex Board’ thrown around. But what exactly is duplex board? In short, it’s a type of paperboard made from two layers of bleached or unbleached pulp, with a different grade of paper on each side. The layers are laminated together to create a sturdy and versatile material that can be used for a variety of packaging applications.
Duplex board is known for its strength and durability, making it a popular choice for packaging products that need to withstand transportation and handling. It’s also a cost-effective option compared to other types of packaging materials, such as corrugated cardboard or plastic. Additionally, duplex board can be coated or laminated with other materials to enhance its properties, such as moisture resistance or printability.

Definition and Properties
Duplex board is a type of paperboard that is composed of multiple layers of pulp. It is known for its sturdiness and strength, making it an ideal choice for packaging and printing applications. The board is made by pasting together layers of pulp from hardwood and softwood trees, which provides it with a unique set of properties that make it suitable for a wide range of applications.
Material Composition
Duplex board is typically composed of two layers of pulp, which are laminated together to create a single sheet of paperboard. The top layer is made from bleached chemical pulp, while the bottom layer is made from unbleached mechanical pulp. The combination of these two layers provides the board with a high level of stiffness and strength, making it ideal for use in packaging and printing applications.
Weight and Thickness
Duplex board is available in a range of weights and thicknesses, depending on the specific application it is being used for. The weight of the board is measured in grams per square meter (gsm), and typically ranges from 200 gsm to 500 gsm. The thickness of the board is measured in microns, and typically ranges from 200 microns to 500 microns.
Surface Finish
Duplex board is available in a range of surface finishes, including matte, gloss, and semi-gloss. The surface finish of the board can have a significant impact on its appearance and performance, as well as its suitability for different applications. Matte finishes are ideal for applications where a more subdued appearance is desired, while gloss and semi-gloss finishes are better suited for applications where a more vibrant and eye-catching appearance is desired.
In summary, duplex board is a sturdy and versatile type of paperboard that is ideal for use in a wide range of packaging and printing applications. Its unique set of properties, including its material composition, weight and thickness, and surface finish, make it a popular choice among manufacturers and designers alike.
