0.5mm 1mm,1.5mm,2mm,3mm Mixed Pulp 250gsm Laminated Grey Board/grey Cardboard/grey Chip Board Roll&sheet Manufacturer

In the competitive landscape of luxury packaging and high-value product manufacturing, the unseen components often dictate the market's perception of quality. The substrate forming the structure of a box, calendar, or display must possess intrinsic strength and unwavering stability. Our Mixed Pulp Laminated Grey Board, available in a comprehensive range of thicknesses from 0.5mm to 3mm and in both roll and sheet formats, is specifically engineered to meet this critical demand. This material is not a commodity cardboard; it is a precision-manufactured board where properties like stiffness, dimensional stability, and resistance to deformation are paramount, making it the definitive choice for manufacturers of jewelry boxes, phone boxes, cigarette boxes, and high-quality calendars.

The standout feature of this grey board lies in its fundamental physical properties, which are a direct result of its manufacturing process and material composition.

The 250gsm weight, consistent across the thickness range, is achieved through a high-pressure consolidation of mixed pulp fibers. This process creates a dense, homogenous core that provides exceptional rigidity relative to its weight. This stiffness is crucial for ensuring that boxes maintain their geometric integrity, providing a "premium feel" when handled and protecting delicate contents from external pressure. A box that buckles or flexes easily communicates poor quality, a risk eliminated by this board's inherent structural strength.

This technical term refers to the exceptional consistency in the board's caliper (thickness) and grammage (weight) across its entire width and from batch to batch. This uniformity is non-negotiable for automated, high-speed production lines. It ensures that during die-cutting, creasing, and folding, every sheet behaves identically, resulting in clean, precise folds and eliminating jams or misalignments. This quantitative stability guarantees that your manufacturing process remains efficient, predictable, and waste-free.

The combination of high stiffness and a laminated surface makes this board highly resistant to warping and twisting, a common issue with inferior chipboards when exposed to fluctuating humidity levels. The lamination process seals the porous core, acting as a barrier against moisture absorption. This dimensional stability ensures that finished products—whether sitting on a shelf for months or shipped across different climates—arrive and remain in perfect, flat, and undistorted condition.

Manufactured from a select blend of mixed pulp, this board offers an optimal balance of surface smoothness, internal fiber strength, and machinability. The lamination applied to the surface further enhances its performance by providing a flawlessly smooth and uniform finish. This surface is ideal for subsequent finishing processes, including high-quality offset printing, foil stamping, embossing, and the application of fabrics or papers, ensuring a pristine final appearance.

Understanding diverse production needs, we supply this grey board in two primary formats: Rolls for high-volume, continuous-feed printing and converting machinery, and Sheets pre-cut to your specified dimensions for streamlined die-cutting and fabrication workflows.

The specific thicknesses offered are tailored to the structural requirements of high-value industries. The following table provides a clear guide to selecting the optimal caliber for your application:

By integrating this precision-engineered laminated grey board into your production, you are not merely purchasing a material; you are investing in the structural integrity, manufacturing efficiency, and perceived value of your final product. It is the reliable, high-performance foundation that allows your designs to be realized with confidence and consistency.
