Double Side Laminated Grey Board 70*100cm Sheets 1.5mm 2mm 2.5mm 3mm White Kappa Board

In the world of high-end packaging and display, structural integrity is non-negotiable. Our Double Side Laminated Grey Board stands as a testament to this principle, engineered to be the foundational core for products that demand uncompromising durability and a flawless finish. Available in standard sheets of 70x100cm and critical thicknesses of 1.5mm, 2mm, 2.5mm, and 3mm, this board is the material of choice for converters and brands seeking to create packaging that not only protects but also profoundly impresses.

The term "Grey Board" or "Grey Cardboard" often belies its sophistication. Our product is manufactured from a selected Mixed Pulp recipe, which is calibrated to achieve an exceptional balance between weight, stiffness, and machinability. The defining feature of this specific product is its Double Side Lamination. This process involves applying a smooth, consistent surface layer—most commonly in a pristine White Kappa Board finish—to both sides of a robust grey core. This lamination achieves two primary objectives: it creates a perfectly uniform surface for high-quality printing and finishing, while simultaneously enhancing the board's inherent rigidity and resistance to warping.

The performance characteristics of this board are directly tied to its physical properties. With a substantial Grammage (GSM) range of 250 to 2600 gsm and a Thickness range from 0.3mm up to a formidable 4mm, it offers unparalleled versatility. This means the same material can be used for a sleek, rigid phone box requiring a 1.5mm board as effectively as for a large, protective jewelry box or display stand necessitating a 3mm or thicker sheet. The core of the board can be customized in terms of its composition and density, allowing for precise control over the final product's weight, bendability, and compression strength.

A key feature is its good cardboard stiffness and stable lateral quantitative, meaning the weight and density are consistent across the entire sheet. This consistency is critical in industrial die-cutting and creasing processes, as it ensures that every blank produced is identical, leading to faster assembly and a superior final construction. The board is not easy to deform, even under fluctuating humidity conditions, guaranteeing that the luxurious packaging you design is the same packaging the end-user receives, perfectly square and robust.

While the board is typically supplied uncoated to facilitate specific adhesion processes, special requests for coating can be accommodated to achieve particular tactile or barrier properties. Its excellent surface, post-lamination, is ideally suited for advanced finishing techniques including foil stamping, embossing, UV spot varnishing, and high-fidelity offset printing.

The applications for this sturdy material are extensive and focused on the premium segment. It is the ideal substrate for:

 Providing the heft and protection that luxury items deserve.

 Offering superior shock resistance and a premium unboxing experience.

 Requiring specific rigidity and a high-quality print surface.

 Delivering the durable, flat surface necessary for long-term use.

 Standing firm under the weight of products in retail environments.

We understand that committing to a new material requires confidence. Therefore, samples are available for you to test its performance firsthand. Furthermore, we offer exceptional flexibility in packaging, which can be supplied in standard sheets or custom-cut to your requested sizes, minimizing waste and optimizing your production workflow.

In conclusion, our Double Side Laminated Grey Board is more than just a material; it is a strategic component for building brand value through packaging. It combines the robust, unyielding character of a high-density grey core with the refined, print-ready surface of white Kappa board lamination. This synergy creates a substrate that meets the most demanding requirements for strength, consistency, and aesthetic potential, making it an intelligent and reliable choice for any business serious about making a lasting physical impression.
