Understanding Coated Duplex Board with Grey Back An Overview of Manufacturing and Applications

Coated duplex board with grey back is a specialized type of packaging material that is widely used in various industries. This paperboard is characterized by its unique construction, offering a smooth, coated surface on one side and a grey fiber layer on the reverse side. The combination of these features makes it highly sought after in sectors such as printing, packaging, and cardboard manufacturing.

What is Coated Duplex Board?

Duplex board is a type of paperboard made from multiple layers of pulped fibers. The coated aspect refers to a layer of coating that is applied to one side of the board, enhancing its printability and surface quality. The grey back is typically produced using recycled fibers, making this product not only cost-effective but also environmentally friendly.

The Grey back of the duplex board is often used as a substrate for various types of printing. The grey color provides an optimal background that can enhance the vibrancy of inks while also concealing any printing flaws or imperfections. This makes coated duplex board an excellent choice for the packaging of products that require an appealing look and feel.

Manufacturing Process

The manufacturing process of coated duplex board begins with the selection of raw materials, primarily wood pulp and recycled fibers. The quality of the pulp directly influences the strength and durability of the final product. Manufacturers often emphasize sustainable sourcing to create an eco-friendly product.

Once the raw materials are chosen, the pulping process begins, in which the fibers are processed and refined. This involves breaking down the wood into pulp, which is then washed and bleached, depending on the desired quality. The next step is forming the board. The pulp is spread into sheets, which are then pressed and dried to achieve the right thickness and moisture content.

After the basic board is formed, the coating process takes place. The coating is typically made from materials like clay, latex, or other polymers, applied to one side for enhanced smoothness and printability. The coated side is then dried and cured to ensure durability. Finally, the grey back is achieved by applying recycled fiber layers, which adds to the board's stiffness and structure.
