25 September 2026

Key Takeaways:

FBB is a versatile paperboard for folding cartons, offering a balance of stiffness, bulk, lightweight construction and printability.
Different paperboard types suit different packaging needs, with FBB, SBS, recycled paperboard and kraft paperboard differing in their fiber composition, appearance and performance.
Foopak Hard Size Board is designed for food packaging applications, offering high stiffness, dimensional stability and printability for applications such as cake, chocolate and confectionery packaging.

Choosing the right paperboard is an important part of developing effective packaging. Different paperboard types offer different combinations of stiffness, printability, appearance, weight, sustainability and cost, so the best choice depends on the packaging application and its performance requirements.

Among the commonly used options, Folding Box Board (FBB) is known for its balance of strength, lightweight construction and printability. But how does it compare with other paperboard types such as Solid Bleached Sulfate (SBS), recycled paperboard and kraft paperboard?

What Type of Paper is FBB?

Folding Box Board (FBB) is a multilayer paperboard designed primarily for folding carton applications. Compared with paper, paperboard is thicker and more rigid, providing the structural support needed for packaging.

FBB is generally designed to combine high stiffness, bulk and relatively low weight, making it suitable for folding cartons that need to maintain their shape while remaining efficient to handle and transport. Its smooth, printable surface also makes it suitable for packaging that requires high-quality graphics and strong visual appeal.

These characteristics make FBB particularly useful for food packaging, where the board needs to provide both structural performance and a suitable surface for printing and branding. Depending on the grade, FBB can be used for applications ranging from confectionery and bakery packaging to other folding cartons.

For food packaging applications that require additional rigidity and stability, Foopak offers Foopak Hard Size Board. This high-bulk folding box paperboard is made from virgin fibers sourced from PEFC-certified wood and is designed to maintain its strength and shape, including in chilled or cold-storage conditions. It also features a smooth, printable surface for high-quality graphics.

What is Folding Box Board Used For?

FBB is commonly used for folding cartons where packaging needs to be lightweight while maintaining sufficient stiffness and structural integrity.

Typical applications of FBB include:

Food packaging, such as folding cartons for confectionery, bakery products, snacks and other packaged foods
Foodservice packaging, including takeaway boxes, dessert boxes and other food containers
Chocolate and confectionery packaging, where stiffness and high-quality printing help protect the product and enhance presentation
Cold and chilled food packaging, where the board needs to maintain its strength and shape under low-temperature conditions
Pharmaceutical packaging, where dimensional stability, printability and reliable folding performance are important
Cosmetics and personal care packaging, where appearance and high-quality graphics are key considerations
Retail and consumer packaging, including cartons for a range of everyday products

FBB can also support material efficiency. Its lightweight construction can reduce the amount of raw material required for a package and lower transport weight, although the overall environmental impact depends on the specific board, manufacturing process, coatings and end-of-life system.

Where is FBB Popular?

For FBB, recent market research shows that Asia-Pacific is a particularly strong market, with FBB accounting for 53.78% of the region’s folding-carton market in 2025, according to Mordor Intelligence’s report published in May 2026. The report identifies China as the largest country market, accounting for 46.63% of Asia-Pacific’s folding-carton market in 2025, while India is projected to be the fastest-growing major market, at a CAGR of 10.15% through 2031.

Understanding the Differences Between Folding Box Board and Other Paperboard Types

FBB is not automatically the best choice for every packaging application. SBS, recycled paperboard and kraft paperboard each have characteristics that may make them more suitable depending on the product, design and performance requirements.

Differences Between FBB and SBS

SBS stands for Solid Bleached Sulfate. It is generally made from bleached virgin chemical pulp throughout the board, whereas FBB uses a multilayer structure combining chemical pulp with a high-yield middle layer.

The difference in construction affects how each board performs.

FBB is often selected when lightweighting, stiffness and material efficiency are important. Its multilayer structure provides high bulk and stiffness while maintaining a printable surface.

SBS, meanwhile, is known for its bright, uniform white appearance and high-quality printing surface. It is often preferred for premium packaging where color reproduction, surface appearance and a clean white interior are particularly important.

In simple terms:

Choose FBB when stiffness-to-weight performance and material efficiency are priorities.
Choose SBS when premium whiteness, print quality and a uniform white appearance are especially important.

The choice ultimately depends on the product and packaging requirements rather than simply which board is considered higher quality.

Differences Between FBB and Recycled Paperboard

Recycled paperboard is made using recovered paper fibers, although the exact composition can vary between grades. Coated recycled board (CRB), for example, is commonly used for folding cartons and other packaging where recycled content and cost efficiency are important.

Compared with recycled paperboard, FBB is commonly associated with virgin-fiber construction and a multilayer structure designed to achieve a high stiffness-to-weight ratio. This can make it suitable for packaging where structural performance, printability and a clean appearance are important.

Recycled paperboard can be an attractive option when recycled content is a major consideration, particularly for applications where the appearance and performance requirements can accommodate the characteristics of recovered fibers.

The key difference is therefore not simply whether one material is “better” for sustainability. Factors such as fiber sourcing, manufacturing, coatings, transportation and the availability of recycling infrastructure all contribute to a packaging material’s overall environmental profile.

Differences Between FBB and Kraft Paperboard

Kraft paperboard is valued for its strength and is commonly used for packaging applications that require structural durability. Unbleached kraft grades can also provide a distinctive natural appearance that supports brands looking for a more rustic or natural packaging aesthetic.

FBB generally offers a different balance. Its layered construction and bleached outer surfaces can provide high stiffness with relatively low weight, along with a surface suitable for detailed graphics and branding.

Kraft paperboard may therefore be a better fit when:

High structural strength is a priority
A natural or kraft appearance suits the brand
The package needs to handle heavier products or demanding applications

FBB may be preferable when:

Lightweighting is important
The package requires good folding and stiffness
High-quality graphics are an important part of the design
A clean, bright printable surface is desired

Ultimately, board selection should consider the complete packaging system, including product weight, carton design, printing process, converting requirements, storage conditions and end-of-life considerations.
