Choosing a packaging board is not simply a paper specification exercise. The board influences print quality, stiffness, folding performance, appearance, food-contact suitability and ultimately how the finished pack performs on the production line and in the market.
Three commonly discussed categories are FBB, SBS and Duplex Board. They may appear similar on a product comparison sheet, but their construction and intended applications can be quite different.
FBB: lightweight strength with strong print performance
Folding Box Board (FBB) is widely used for folding cartons where stiffness, bulk and printability are important.
Its multi-layer construction allows manufacturers to achieve a strong stiffness-to-weight balance, making it suitable for applications such as food, pharmaceutical, personal-care and consumer packaging, depending on the grade and required certifications.
For premium printed packaging, surface quality is particularly important because the board must support high-quality graphics and finishing.
SBS: a premium choice for demanding applications
Solid Bleached Sulphate (SBS) is a virgin-fibre paperboard known for its clean, bright appearance and strong printing characteristics.
It is frequently considered where premium aesthetics, surface quality and structural performance are important—for example, luxury consumer packaging, cosmetics, pharmaceuticals and selected food applications.
The exact grade and certification remain critical, particularly for direct or indirect food-contact applications.
Duplex: efficiency with strong packaging performance
Duplex board is commonly produced in multi-layer constructions and can offer a practical combination of stiffness, printability and cost efficiency.
Grey-back duplex grades are often used where the application does not require the premium appearance of fully white premium boards. They are common in FMCG, general consumer packaging and industrial packaging.
So which one should you choose?
The answer depends on the packaging objective.
Choose based on: Product type + print requirement + stiffness + folding/converting process + food-contact requirement + visual positioning + target cost
For example, a premium cosmetic carton may prioritise whiteness and print reproduction. A mass-market secondary carton may place greater emphasis on cost and structural performance.
A board should therefore be selected backward from the finished packaging requirement—not forward from the lowest available price.
That distinction matters in global sourcing, where the right specification can reduce conversion losses, improve pack performance and create a better total cost than simply choosing the cheapest board.
