Understanding Duplex Paper Types A Comprehensive Guide

Duplex paper is a popular choice in the printing and packaging industries due to its versatility, strength, and cost-effectiveness. Made from two layers of paper, duplex paper is characterized by its smooth surface on one side and a more textured or uncoated finish on the other. This distinctive feature makes it suitable for a variety of applications, from packaging products to producing high-quality printed materials. In this article, we will explore the different types of duplex paper products, their properties, and their common uses.

Types of Duplex Paper

1. SBS (Solid Bleached Sulfate) SBS duplex paper is known for its excellent print quality and white color. Made from bleached wood pulp, it is primarily used for packaging and products that require vibrant color reproduction. The smooth, bright surface allows for intricate designs, making it ideal for items such as cosmetics, food packaging, and high-end boxes. Due to its durability, SBS is also widely used for folding cartons, which are designed to hold fragile items.

2. CUS (Coated Unbleached Sulfate) CUS duplex paper features an unbleached surface, providing a natural and earthy feel. This type of duplex paper is typically brown or gray and is made from a mixture of recycled fibers and virgin pulp. CUS is often used in packaging goods where a robust, environmentally friendly option is required. Common applications include food packaging, shipping boxes, and retail bags. Its strength and sustainability make it a favorite among eco-conscious brands.

3. Greyboard Greyboard is a type of duplex paper that uses recycled paper fibers, giving it a thick, sturdy structure. It is typically grey in color and has a rough surface, making it suitable for applications where rigidity is crucial. Greyboard is widely used in making backings for notebooks, as well as in the production of high-quality packaging products, such as cartons and display panels. Its ability to withstand pressure and weight makes it a go-to choice for various industrial applications.

4. Chipboard Similar to greyboard, chipboard is another duplex paper product made from recycled fibers. However, chipboard tends to be thinner and is often used in applications like game boards, packaging for lightweight products, and backing for picture frames. It provides a lightweight yet sturdy solution, making it easy to work with during the construction of various products.

5. Chromolux Chromolux is a high-quality duplex paper featuring a glossy finish on one or both sides. This type is particularly popular in the creation of high-end brochures, business cards, and other marketing materials that require a professional appearance. The glossy surface enhances color vibrancy and sharpness, making it a staple among businesses looking to present themselves in a polished light.
