What Is Folding Box Board

Folding Box Board (FBB), also known as "folding carton board" or "folding carton board", is a multi-layer paperboard material, usually composed of three or more layers of different types of pulp:

Top layer (surface layer): Made of high-quality bleached chemical pulp, with a smooth surface, suitable for high-quality printing.

Middle layer: Made of unbleached mechanical pulp, this layer is usually thicker and provides the main thickness and strength of the paperboard.

Bottom layer (bottom surface): Made of recycled fiber or unbleached pulp, although not as smooth as the top layer, it can also be simply printed.

Main characteristics of FBB

Lightweight and high strength: FBB has high strength and rigidity, can provide good support, and is light in weight, which is easy to transport and handle.

Excellent printability: Its smooth surface is very suitable for high-quality printing, and can present clear and bright images and texts. It is widely used in the packaging of high-end products.

Environmental protection: FBB is usually made of renewable fibers and is easy to recycle and recycle. It is an environmentally friendly packaging material.

Easy processing: FBB has good folding and processing performance, can be easily die-cut, embossed and bonded, and is suitable for automated production lines.

Moisture resistance: FBB can be specially treated to improve its moisture and humidity resistance, suitable for food and pharmaceutical packaging.

Application areas of FBB

Due to its excellent characteristics, FBB is widely used in packaging needs of various industries. The following are some of the main application areas:

Food and beverage packaging: FBB is often used to package various foods and beverages, such as candy, tea, dried fruits, frozen foods and milk, etc. It can well protect the contents and is suitable for direct contact with food.

Cosmetic and pharmaceutical packaging: Cosmetics and pharmaceuticals require high-end packaging to enhance the product image. FBB can provide high-quality printing effects and solid protection.

Consumer electronics packaging: FBB is suitable for packaging small electronic products, such as mobile phone accessories, headphones, smart watches, etc., and can provide good protection during transportation.

Retail product display: FBB is also widely used to make display boxes and billboards for retail products, which have good visual effects and appeal.

Manufacturing process of FBB

The production process of FBB includes the following main steps:

Pulping: converting wood or other fiber raw materials into pulp, removing impurities through bleaching and chemical treatment.

Papering: coating the pulp into a thin layer, pressing, drying and coating to form a multi-layered paperboard.

Surface treatment: surface coating or laminating treatment is performed to enhance the printing performance and moisture resistance of the paperboard.

Cutting and packaging: cutting the finished paperboard into the required size and packaging it for shipment.

Comparison of FBB with other packaging materials

FBB vs. SBS (bleached kraft paperboard): SBS is mainly made of bleached chemical pulp and is usually used for high-end product packaging, while FBB adopts a multi-layer structure to provide higher rigidity and cost-effectiveness.

FBB vs. CCNB (coated kraft paperboard): CCNB is made of recycled fiber, with a lower price but inferior strength and printing effect to FBB, and is mainly used for ordinary packaging.

FBB vs. Corrugated Board: Corrugated board is suitable for packaging large and heavy products, while FBB is more suitable for small and medium-sized products, especially those that require exquisite printing.
