What is FBB(Folding Box Board)?
Folding Box Board (FBB), also known as Ivory Board or by its industry codes GC1 and GC2, is a high-quality paperboard made from multiple layers of chemical and mechanical pulp. Its unique “sandwich” construction—mechanical pulp between two layers of bleached chemical pulp—gives it exceptional bulk and stiffness while remaining lightweight.
What is SBS (Solid Bleached Sulphate)?
Solid Bleached Sulphate (SBS), sometimes called SBB (Solid Bleached Board), is the “gold standard” of paperboard. It is manufactured entirely from 100% bleached chemical pulp. This results in a solid white sheet throughout—not just on the surface—offering the highest level of brightness, purity, and hygiene.
For applications where quality and aesthetics are paramount, Amar Trading Company offers premium Solid Bleached Sulphate (SBS) and Folding Box Board (FBB). These virgin fiber paperboards are the gold standard for high-end packaging and graphic communications, providing a luxurious feel and unmatched performance.”
FBB provides high rigidity without adding weight. This means you can use a lower GSM (grams per square meter) to achieve the same strength as thicker materials, saving on shipping costs.
SBS is white on the front, back, and even the "core" (the edge of the paper). This provides a clean, medical-grade aesthetic.
FBB is engineered to be creased and folded without cracking, which is essential for automated packaging lines.
SBS has the smoothest surface of any paperboard. This allows for high-definition graphics, vibrant colors, and sharp text with minimal ink absorption.
FBB has premium feel with excellent print quality while keeping material weight and cost low.
SBS purity makes it FDA-compliant and safe for direct food contact and pharmaceutical packaging.
