In the procurement of high-end folding cartons, SBS white core white card and FBB yellow core white card are the two most frequently compared materials, especially suitable for beauty gift boxes, tobacco and alcohol color boxes, medical folding boxes, and high-end food packaging. Many purchasers often confuse the two, leading to material selection errors and affecting the packaging texture and product grade. The core differences between the two lie in raw materials, appearance, performance, and application scenarios. Accurate differentiation is necessary to select the appropriate material.
SBS white core white card is made from fully bleached sulfate wood pulp, featuring a three-layer structure that is pure white throughout, free of impurities and blemishes, with a whiteness of up to 88+. The paper surface is smooth and fine, with strong ink adhesion, suitable for various fine post-printing processes such as hot stamping, UV matte, embossing, and lamination. It does not burst during die-cutting, does not crack when folded, and has excellent folding endurance and moisture resistance. It also meets FDA food contact standards and EU environmental protection certifications, making it the preferred material for high-end packaging and gift boxes in foreign trade exports. Common grammages range from 230g to 350g, suitable for cigarette packs, high-end cosmetic boxes, and medical packaging boxes.
FBB yellow core white card has a sandwich structure, with the surface and bottom layers made of chemical wood pulp and the middle core layer made of mechanical wood pulp. The cross-section is naturally yellow. Compared to SBS white core white card, it is thicker and stiffer at the same grammage, with lower raw material costs and a high cost-performance ratio. However, its whiteness and smoothness are inferior to those of SBS white core white card, and the yellow cross-section affects its refinement. It performs poorly in fine hot stamping and mirror printing, and is prone to color change and deformation when exposed to moisture for a long time. It is commonly used in ordinary daily chemical packaging, mass consumer goods color boxes, and mid-range general folding cartons, suitable for bulk orders with lower packaging grade requirements and a focus on cost control.
