Duplex board is a kind of paperboard or cardboard. It consists of two layers, or plies, so
people call it duplex board. The exterior of the board is coated, often with a bright white
appearance, to make it more water-resistant and to give it a glossy sheen, but even
uncoated duplex board is strong enough to make disposable cups and plates.

Duplex paperboard is eco-friendly as it is made from 100% recycled paper material. Duplex board is a less expensive variant of whiteboard; with similar surface finishing that provides a comparable printing surface to that of the more expensive whiteboard.

The advantage of the duplex board is tough, durable, straight and is able to take on a bright white appearance, unlike common corrugated cardboard. At High Land, it is commonly used to create rigid boxes for a variety of luxury small goods. For example, it is often used in pharmaceutical cartons, rigid shoe boxes, garment boxes, toy packaging and cigarette packs.

The uncoated duplex board is often wrapped with art paper and specialty paper to build
rigid boxes with fantastic artwork printing.
