What is Folding Box Board?

Introduction

Have you ever struggled with packaging that deforms easily? Or printing colors that don’t turn out as expected? These common frustrations plague many brands, but the solution might be simpler than you think—a high-quality paperboard called Folding Box Board (FBB), also known as Ivory Board. In this article, we’ll explore everything you need to know about FBB, including its features and how it can help solve these packaging challenges.

What is Folding Box Board?

Folding Box Board (FBB), also referred to as Ivory Board, gets its name from its ivory-white color. It is a high-quality, sturdy paperboard made entirely from virgin wood pulp. Through chemical bleaching and calendering, FBB achieves a high level of whiteness and smoothness, providing a flawless surface free from streaks and spots. Structurally, FBB consists of multiple layers: a top layer, a core layer, and a bottom layer. The core layer increases the board’s thickness and enhances its strength, giving it excellent rigidity and resistance to warping. Because of its multi-layer structure, FBB is lighter in weight compared to solid bleached board (SBB) or other single-ply paperboards with the same thickness. This lightweight yet stiff property makes it particularly attractive for global brands that want to reduce shipping costs while still maintaining premium packaging strength.

Types of Folding Box Board

FBB comes in both single-coated and double-coated varieties, known as  C1S (Coated One Side) Ivory Board and C2S (Coated Two Sides) Ivory Board. Additionally, FBB is classified based on the type of pulp used in its core:

GC1 (Coated FBB White Back): Features a bleached chemical pulp core, offering superior whiteness and uniformity.

GC2 (Coated FBB Manila Back): Uses mechanical pulp in the core, resulting in a slightly yellowish hue but greater stiffness.

C1S Ivory Board

C1S is commonly used for packaging where only one side is visible. Since only one side requires coating, it is cost-effective while still delivering high whiteness and a smooth printing surface. It is widely used for pharmaceutical, cosmetic, and food packaging. However, C1S should not come into direct contact with food. If you need a packaging solution that requires single-sided printing with no backside requirements, C1S is an economical choice. Another advantage of C1S is its adaptability to post-print processes such as hot stamping, embossing, and lamination. Many pharmaceutical and cosmetics companies choose C1S because it not only supports clear text and images on the front side but also works well with anti-counterfeiting features like holograms or security strips.

C2S Ivory Board

C2S is coated on both sides, providing a smooth, high-brightness surface on both the front and back. This makes it ideal for high-quality four-color printing, ensuring vivid color reproduction and long-lasting print durability. It is commonly used for luxury packaging, electronics packaging, perfume boxes, and wine boxes, where double-sided premium print quality is essential. In addition, C2S is widely used for export packaging where international clients demand consistent print quality on both sides of the box. For example, luxury chocolate brands and high-end electronics often select C2S for its ability to convey a sophisticated, uniform brand image across all surfaces of the packaging.

GC1 (Coated FBB White Back)

GC1 has a white pulp core made from pure virgin wood fibers, resulting in a more uniform and high-whiteness appearance. The surface is finer and provides a more premium look and feel. Additionally, GC1 offers excellent flexibility, stiffness, and durability, making it suitable for high-end packaging applications such as cosmetics, luxury goods, electronics, and jewelry boxes. If you are looking for a premium packaging material that enhances your brand’s image, GC1 is an excellent choice. GC1 is also favored in markets where product safety and hygiene are critical, as its bleached fiber composition provides a cleaner, odor-free surface. This makes it suitable for cosmetics, skincare, and healthcare products, where both appearance and purity are equally important.

GC2 (Coated FBB Manila Back)

GC2, with its mechanical pulp core, has a slightly yellowish tint because the pulp is unbleached. However, GC2 is known for its higher stiffness and hardness. Compared to GC1, it provides better rigidity at the same weight, making it ideal for rigid packaging applications. GC2 is commonly used for daily necessities, food packaging, shoe boxes, and toy packaging—especially when high stiffness is required but premium print quality is less critical. GC2 is often the material of choice for e-commerce and mass-market packaging. Its superior stiffness ensures that packages maintain shape during transportation, protecting goods from damage. Shoe brands, toy manufacturers, and FMCG companies value GC2 because it provides strong protection at a lower cost compared to premium FBB grades.
