Paper boards, also known as cardboard or paperboard, are an indispensable material in various industries due to their lightweight, durable, and eco-friendly properties. As consumer demand grows for sustainable and efficient packaging solutions, paper boards have emerged as a top choice for businesses and consumers alike. This article explores the characteristics, types, applications, and environmental benefits of paper boards.

Paper boards are thick, flat sheets of compressed paper pulp, typically with a thickness greater than 0.3 millimeters. Unlike standard paper, paper boards are designed to provide greater strength and rigidity, making them ideal for packaging, crafting, and industrial applications. They come in various grades and finishes, catering to diverse needs.

### **Types of Paper Boards**

1. **Solid Bleached Sulfate (SBS):**
Made from chemically processed wood pulp, SBS boards are coated with a clay finish to offer a smooth, printable surface. These are widely used in high-end packaging for cosmetics, pharmaceuticals, and food products.

2. **Coated Unbleached Kraft (CUK):**
Made from unbleached wood fibers, CUK boards are known paper boards for their durability and are often used in beverage packaging and other heavy-duty applications.

3. **Folding Boxboard (FBB):**
Made from mechanical and chemical pulp layers, FBB is lightweight and ideal for folding cartons, retail packaging, and graphic printing.

4. **Recycled Paper Board:**
As the name suggests, this type is manufactured using recycled paper materials. It’s commonly used in packaging for non-food items, including electronics and household goods.
