Composite Grey Board: The Architectural Foundation for Premium Packaging

In the world of luxury packaging, the unspoken hero is often the material that forms its very foundation. It is the skeleton upon which beauty is built, the element that confers a sense of substance, value, and durability. Our Composite Grey Board Sheets are engineered to be precisely that—the superior structural core for rigid boxes that demand excellence.

Crafted from a specialized blend of recycled and virgin fibers (Mixed Pulp), our grey board is a testament to sustainable strength. Unlike standard cardboard, the composite construction involves a meticulously calibrated inner core, which can be customized for specific performance needs, sandwiched to create a remarkably rigid and stable sheet. This process eliminates warping and ensures a flawless, precision fold every time, which is paramount for high-speed automated packaging lines and meticulous hand-finishing alike.

Unmatched Versatility in Specification

Understanding that no two products are the same, we offer an exceptional range of customization. Whether you require a slender yet sturdy 0.3mm board for a sleek publication cover or a formidable 4mm thick sheet for a heavyweight electronics gift box, our production capabilities are designed to meet your exact specifications. This flexibility extends to the Grammage (GSM), allowing you to fine-tune the weight and density of the material from a substantial 250 gsm to an ultra-heavy-duty 2600 gsm, ensuring the perfect hand-feel and protective quality for your product.

A Canvas for Your Brand's Identity

The classic grey hue of our board offers a neutral and professional base, ideal for applications where the interior structure is part of the aesthetic. For projects requiring a brighter, more refined finish, we offer the popular "Grey board with one side whiteboard." This variant provides the same robust grey core with a pure white, pre-finished surface on one side, ready for immediate printing, foil stamping, or embossing. This eliminates the need for an additional lining step, saving time and cost while guaranteeing a pristine background that makes colors pop and details shine. We also offer consistent black and solid white options for dramatic or minimalist designs.

Available in sheets cut to your requested dimensions, we ensure you receive the material ready for your production process, minimizing waste and maximizing efficiency. From rigid gift boxes and high-end cosmetic cases to bookbinding, game boards, and high-value product inserts, Composite Grey Board is the intelligent choice for designers and brands who refuse to compromise on quality.
