Understanding Duplex Paper Meaning and Manufacturers

Duplex paper is a specialized type of paper that plays a crucial role in various printing and packaging applications. It is characterized by its unique structure and properties, making it a preferred choice for manufacturers and designers around the world. In this article, we will explore the meaning of duplex paper, its types, uses, and a look into some prominent manufacturers in the industry.

What is Duplex Paper?

Duplex paper is a type of paperboard that consists of two layers or plies. These layers are typically made from different types of pulp, with one side often coated for printing purposes and the other side untreated. The coated side usually has a smoother finish, which enhances image clarity and color vibrancy, making it ideal for high-quality printing. The untreated side is generally more robust and is often used for packaging purposes, providing strength and durability.

The two layers in duplex paper can vary in weight, thickness, and texture. This versatility makes duplex paper suitable for a range of applications, from lightweight cartons and boxes to heavier packaging solutions. The paper is often available in various grammages, ranging from 200 to 500 grams per square meter (gsm), catering to different needs in the market.
