In the fields of packaging, printing, and binding, the physical properties of cardboard directly determine the texture and service life of the finished product. Lige brand gray cardboard has become a benchmark product for high-end industrial cardboard due to its outstanding flatness, stiffness, smoothness, and deformation resistance, providing solid guarantees for customers who pursue precision quality.

Analysis of Core Advantages
1. Extremely straight, precise processing with zero error
The standing grid gray board adopts high-quality gray board paper raw materials and multi-layer composite technology, combined with precision hot pressing shaping technology, to control the internal stress of the cardboard from raw materials to finished products. The flatness error of the finished product is small, and even with large-scale cutting, there is no warping, ensuring precise alignment of printing, die-cutting, mounting and other processes, significantly reducing production losses.
2. High weight and rigid structure, capable of bearing and resisting pressure without collapsing
By scientifically proportioning fiber density and interlayer bonding technology, the weight range of standing grid gray board covers 700-3000g/㎡, and the hardness is increased by 40% compared to ordinary cardboard. Suitable for scenes such as producing hardcover book cases and luxury gift boxes that require long-term maintenance of three-dimensional structure, without deformation or cracking after prolonged storage.
3. Double sided precision polishing provides a delicate and high-end touch
The innovative surface adhesive hot pressing process endows the cardboard with a silky smooth touch on both sides. Fine processing such as hot stamping and UV printing can be directly carried out without the need for additional film coating, which not only reduces production costs but also presents a matte high-end texture, perfectly matching the packaging needs of high-end brands.
4. Recommended application scenarios
Premium packaging: luxury jewelry boxes, electronic product liners, etc
Cultural printing: hardcover book covers, art brochure backboards, puzzles, etc
Commercial display: high-end booth structural panels, store signage, etc
Industrial field: Instrument shock-absorbing pads, precision component packaging, etc
5. Environmental Protection and Certification
Lige brand grey board paper has passed SGS certification and FSC forest certification, using water-based environmentally friendly adhesive, and complies with the EU REACH regulation. Each batch of products undergoes a quality inspection process, providing comprehensive testing reports on bending strength, smoothness, moisture content, and other aspects, ensuring that the quality is qualified.

Choosing standing grid gray board is not only about choosing a material, but also about pursuing the ultimate craftsmanship. We empower traditional paper products with technology, allowing every millimeter of thickness to carry reliable quality, helping your products showcase extraordinary style in details.
