FBB (Folding Box Board) sheets are a type of paperboard that is commonly used for packaging applications. FBB sheets are known for their high-quality surface, strength, and versatility. Here is some information about FBB sheets:

1. Composition: FBB sheets are typically composed of multiple layers of bleached chemical pulp. The layers are bonded together to form a single sheet of paperboard. The use of high-quality pulp ensures a smooth and consistent surface.
2. Coating: FBB sheets are coated on one or both sides with a layer of clay or other coating materials. The coating enhances the surface smoothness, brightness, and printability of the paperboard. It also improves the ink absorption and color reproduction.
3. Thickness and Weight: FBB sheets are available in different thicknesses and weights, ranging from lightweight to heavyweight options. The thickness is measured in terms of the paper’s weight, which is expressed in grams per square meter (gsm) or pounds (lb). Common weights for FBB sheets range from 200 gsm to 400 gsm or higher.
4. Printability: FBB sheets offer excellent printability, allowing for high-quality graphics and vibrant colors. The smooth and coated surface ensures sharp and clear printing results. FBB sheets are compatible with various printing techniques, including offset printing, digital printing, and screen printing.
5. Folding and Creasing: FBB sheets have good folding and creasing properties, making them ideal for packaging applications that require folding or die-cutting. They can be easily folded without cracking or breaking, allowing for efficient packaging assembly.
6. Surface Finish Options: FBB sheets are available in different surface finishes, such as gloss, matte, or satin. The choice of surface finish depends on the desired visual appeal and the specific packaging requirements.
7. Strength and Durability: FBB sheets are known for their strength and durability. They offer good stiffness, rigidity, and resistance to bending or warping. This makes them suitable for applications where structural integrity is important, such as cartons, boxes, or other packaging containers.
8. Environmental Considerations: Many FBB sheets are made from sustainable and responsibly sourced fibers. Additionally, FBB sheets are recyclable, which helps reduce waste and promote environmental sustainability.

FBB sheets are widely used in various packaging applications, including food packaging, cosmetics packaging, pharmaceutical packaging, and consumer goods packaging. Their smooth surface, excellent printability, and strength make them a preferred choice for creating visually appealing and durable packaging solutions.
