0.3mm 1mm 1.5mm 2mm 3mm 4mm Laminated Grey Board/chip Board/rigid Cardboard for Book Binding

In the demanding fields of high-quality book publishing, luxury packaging, and commercial printing, the substrate is not merely a component—it is the fundamental element that determines the longevity, functionality, and perceived value of the final product. Our calibrated range of Laminated Grey Board, also known as chipboard or rigid cardboard, is scientifically manufactured to provide an uncompromising foundation. Available in a precise spectrum of thicknesses from 0.3mm to 4mm, this material is engineered for applications where dimensional stability, structural integrity, and a superior finishing surface are critical operational requirements. This product represents a fusion of traditional board-making techniques with modern quality control, resulting in a consistently reliable performance substrate for industrial and artisanal use.

The functional superiority of this board is defined by a set of measurable, key physical characteristics that directly impact manufacturing efficiency and product durability.

 The primary characteristic of this board is its exceptional stiffness-to-weight ratio. This rigidity is a direct function of its multi-ply, high-density fibrous structure, which is consolidated under controlled pressure and heat. This inherent stiffness ensures that products like book covers and packaging boxes resist bending forces, maintaining a crisp, authoritative feel and protecting the contents within from external pressure. This is not a passive material; it is an active structural component.

 In automated production environments, material variance is a primary source of downtime and waste. Our manufacturing process is calibrated to deliver outstanding batch-to-batch and sheet-to-sheet consistency in caliper (thickness) and grammage. This "stable lateral quantitative" property guarantees that the board feeds flawlessly through high-speed die-cutters, foil stamping presses, and perfect binding systems, ensuring precise registration and significantly reducing machine jams and material rejection.

 The board is specifically processed to mitigate the common issue of warping and curling. Its balanced construction and moisture-resistant properties prevent deformation that can be caused by ambient humidity or the application of adhesive layers and laminates. This ensures that sheets remain flat during storage and processing, and that the finished products—whether a hardcover book or a rigid box—retain their intended geometry over time, avoiding the unprofessional appearance of a warped cover or lid.

The graduated thickness range from 0.3mm to 4mm allows for precise material selection based on functional and economic requirements.

 The 0.3mm to 1.5mm boards are ideal for creating durable hardcover book covers, providing a robust base that can be easily case-bound. The 2mm to 4mm grades are perfect for high-page-count novel covers, textbook covers, and the rigid boards used in photo albums and portfolio cases, ensuring the spine and covers withstand repeated handling.

 This board is the material of choice for constructing high-end jewelry boxes, phone boxes, and cigarette boxes. Its rigidity allows for the creation of boxes with sharp, well-defined edges that communicate luxury. The smooth, laminated surface is an excellent substrate for direct printing, foil stamping, or the seamless application of specialty papers, textiles, or synthetic leather.

 For calendars, the 1.5mm to 3mm board provides a sturdy backing that hangs flat without sagging. It is equally effective for point-of-sale displays, menu covers, and high-end presentation folders, offering a professional, rigid feel that commands attention.
