Folding Boxboard (FBB) is a high-quality paperboard grade composed of multiple layers of chemical and mechanical pulp, designed to deliver both strength and aesthetic appeal. Its unique multi-ply construction features a middle layer of mechanical pulp sandwiched between two outer layers of chemical pulp. The top layer typically consists of bleached chemical pulp, often enhanced with an optional pigment coating for a superior printable surface. Meanwhile, the mechanical pulp core provides increased thickness (caliper) at the same grammage, resulting in enhanced rigidity without adding extra weight.

One distinguishing characteristic of FBB is its slightly yellowish hue, primarily visible on the inner layer, which stems from the mechanical pulp content. Despite this subtle tint, the exterior maintains a bright, polished appearance, making it ideal for high-end packaging applications where visual presentation matters.

FBB Layer Construction

FBB’s layered structure ensures optimal performance in both functionality and printability:

1. Coating (Optional) – A smooth, clay-based coating can be applied to improve surface gloss, whiteness, and ink adhesion for vibrant printing.
2. Bleached Chemical Pulp (Top Layer) – Offers a bright, clean surface ideal for high-resolution graphics and branding.
3. Mechanical Pulp (Middle Layer) – Provides bulk and stiffness, reducing material usage while maintaining structural integrity.
4. Unbleached/Bleached Chemical Pulp (Bottom Layer) – Ensures stability and a clean interior, suitable for direct contact with sensitive products like food and pharmaceuticals.

Key Applications of Folding Boxboard

Thanks to its versatility, FBB is widely used in industries that demand both durability and premium aesthetics:

• Pharmaceutical Packaging – Ensures product safety with a sturdy yet lightweight material.
• Cosmetics & Beauty Products – Enhances shelf appeal with a smooth, printable surface perfect for luxury branding.
• Confectionery & Sweets – Provides an attractive and protective solution for chocolates, biscuits, and gourmet treats.
• Tobacco Industry – Commonly used for cigarette boxes due to its rigidity and foldability.
• Beverage Packaging – Ideal for wine and liqueur boxes, offering structural support and a premium finish.
• Frozen & Chilled Foods – Resists moisture and maintains integrity in refrigerated environments.
• Ready-to-Eat Meals – A safe and sustainable choice for pre-cooked food packaging.
