SBS vs. FBB: Understanding the Differences

Unboxing Differences: Solid Bleached Sulphate (SBS) vs. Folding Boxboard (FBB)

For those in the paper conversion industry—whether dealing with mono cartons, greeting cards, or premium packaging—understanding the differences between Solid Bleached Board (SBS) and Folding Box Board (FBB) is crucial. These premium-grade paperboards are widely used in packaging for food, cosmetics, cigarettes, and more. Let’s explore their characteristics and key differences.

What Are SBS and FBB?

SBS and FBB are high-quality paperboards derived from virgin wood fibers, pulped, and bleached to create durable, odorless, and printable surfaces. Available in 150-400 GSM, they offer superior strength compared to recycled paper boards. Both are easily printable, embossable, and customizable, making them ideal for high-end packaging. However, their unique properties make them suitable for different applications.

Solid Bleached Board (SBS)

Also known as ivory paperboard, SBS is made from chemically pulped fibers, flattened into a single-ply sheet. The top surface, and often the reverse side, is pigment-coated, providing a smooth, bright white print surface. Due to its high whiteness and bulk, SBS is considered a premium choice for luxury packaging. However, its higher cost makes it less economical compared to FBB.

Folding Boxboard (FBB)

FBB is a lightweight alternative to SBS, designed to reduce wood consumption without significantly compromising performance. It is a multi-layered paperboard with mechanical pulp sandwiched between outer layers of chemical pulp. While the top layer is bleached and pigment-coated, the inner side has a slightly yellow hue due to the middle layer.

Modern manufacturing technologies allow for the use of lighter-weight pulp in the middle layer, making FBB a rigid yet cost-effective choice. Despite its lightweight composition, FBB performs well in packaging cigarettes, chocolates, cosmetics, and other consumer goods while maintaining excellent creasing, folding, and printability.

Sustainable Packaging & Industry Trends

While FBB is more eco-friendly than SBS due to its efficient use of wood pulp, both materials remain sustainable alternatives to plastic. As brands move towards environmentally friendly packaging solutions, understanding the advantages of SBS and FBB can help in making informed decisions for cost-effective and sustainable packaging.
