Grey board is a rigid paperboard material known for its high stiffness, stable thickness, and reliable structural strength. It is commonly used in products that require strong support, clean converting performance, and good surface flatness. With a grammage range of 250gsm to 2400gsm and thickness from 0.43mm to 4.3mm, grey board is suitable for both lightweight mounting purposes and heavy-duty laminated board applications.
Grey board is made as a dense board material for structural use rather than direct decorative printing. Compared with lighter paperboard grades, it offers better rigidity, stronger compression resistance, and more stable performance during die-cutting, wrapping, laminating, and mounting. Because of these characteristics, it is widely selected for packaging, bookbinding, stationery, and display production where shape retention is important.
Its smooth and even surface also makes it suitable as a base board for lamination with specialty papers, printed sheets, or decorative covering materials. This allows the finished product to combine an attractive exterior with a firm inner structure.
Grey board is valued for its balance of thickness, stiffness, and processing stability. Main features include:
Excellent stiffness for structural support
Smooth and flat surface for mounting and wrapping
Stable thickness for consistent converting results
Wide grammage range from 250gsm to 2400gsm
Thickness options from 0.43mm to 4.3mm
Good suitability for die-cutting, laminating, and forming
Available in different constructions for different strength needs
These features make grey board a dependable material for manufacturers that need strong board performance across a wide range of product types.
Grey board paper is the lighter base material in the grey board range, generally covering 250gsm to 650gsm. It is often used as the foundation for further lamination or compounding, especially where a thinner board structure is required.
Single layer grey board is designed for medium-strength applications. It provides a practical balance between thickness and flexibility, making it suitable for products that need support without using a heavier laminated structure.
Laminated grey board is the strongest option in this category. It is produced through multi-layer lamination to achieve higher thickness and stronger rigidity. This construction is especially suitable for products that need a firm board body and improved dimensional stability.
Grey board is mainly used for:
Rigid boxes
Gift boxes
Hardcover book covers
File folders
Paper hangers
Puzzle bases
Game boards
Calendar stands
These applications require a board material that can maintain shape, resist bending, and support outer wrapping or mounting processes.
One of the main reasons grey board remains widely used is its adaptability. It can serve as a core board, backing board, mounted board, or structural insert depending on the final product design. Thinner grades help reduce material weight, while thicker laminated grades provide additional strength for premium packaging and hardbound products.
Its broad specification range also makes it easier to match the board with different converting requirements. For products that need durability, clean forming, and long-lasting structural support, grey board remains a practical and efficient material choice.
Grey board is used for rigid boxes, book covers, file folders, paper hangers, puzzle bases, game boards, and other products that require strong support and stable shape.
Grey board is available from 250gsm to 2400gsm, depending on the board type and application.
Common thickness ranges from 0.43mm to 4.3mm.
Grey board paper is a lighter base material, while laminated grey board is a thicker and stronger construction made for higher rigidity and structural performance.
