Paper boards are a versatile and indispensable material in numerous industries, ranging from packaging to printing. Known for their durability and adaptability, they are thicker than ordinary paper and come in various grades and types, each suited to specific applications. This article explores the key aspects of paper boards, their types, uses, and the advantages they offer.

What Are Paper Boards?

Paper boards, often referred to as cardboard, are a thicker and more rigid material compared to standard paper. They are typically made by compressing layers of paper pulp or by combining different grades of paper to achieve the desired thickness and strength. The thickness of paper boards is measured in terms of grams per square meter (gsm) or in caliper (thickness in microns).

Types of Paper Boards

1. Solid Bleached Sulfate (SBS):
   • Made from bleached chemical pulp, SBS boards are highly durable and have a smooth, white surface.
   • Commonly used for high-end packaging, printing, and food-grade containers.
2. Coated Unbleached Kraft (CUK):
   • Produced using unbleached chemical pulp, these boards are sturdy and often brown or natural in color.
   • Ideal for beverage carriers, corrugated boxes, and industrial applications.
3. Folding Box Board (FBB):
   • Composed of multiple layers of mechanical and paper boards chemical pulp, FBB is lightweight yet strong.
   • Frequently used for pharmaceutical packaging, cosmetic boxes, and food cartons.
4. Recycled Paper Boards:
   • Made from recycled paper fibers, these are an eco-friendly option.
   • Suitable for secondary packaging, such as shoe boxes and shipping cartons.
5. Chipboard:
   • A low-cost, dense board made from recycled paper.
   • Commonly used for backing in notebooks, book covers, and packaging inserts.

Applications of Paper Boards

Paper boards find utility in a wide array of sectors due to their versatility. Some of their primary applications include:

1. Packaging:
   Paper boards are a popular choice for packaging due to their lightweight, recyclable nature. They are used for food packaging, retail boxes, and protective wraps.
