1. Product Overview​

Greyboard paper is a dense, rigid paperboard primarily made from recycled fibers. Its solid structure and uniform composition make it highly suitable for precise cutting by various types of cutting machines, including digital die - cutting machines, laser cutters, and CNC (Computer Numerical Control) cutting machines. The paper's grey color is a result of using unbleached or minimally processed pulp, which also contributes to its cost - effectiveness and environmental - friendliness.​

2. Key Features​

2.1 High Tensile Strength​

Greyboard paper boasts excellent tensile strength, enabling it to withstand the mechanical forces exerted during the cutting process. Whether it's the sharp pressure of a die - cutting blade or the high - heat focus of a laser cutter, the paper resists tearing, cracking, or deformation. This strength ensures clean, accurate cuts, reducing material waste and improving production efficiency. For instance, in large - scale packaging manufacturing, where high - volume cutting is required, the paper's tensile strength maintains consistent cut quality.​

2.2 Smooth and Flat Surface​

The surface of greyboard paper is smooth and flat, which is crucial for precise cutting. Cutting machines rely on a stable, even surface to ensure accurate alignment and cutting paths. The smoothness minimizes friction between the cutting tool and the paper, allowing for smoother cuts and extending the lifespan of cutting blades or laser nozzles. A flat surface also prevents issues like misalignment or uneven cuts that could occur with warped or textured materials.​

2.3 Consistent Thickness​

Manufactured to strict thickness standards, greyboard paper comes in a variety of thicknesses, typically ranging from 1mm to 6mm. This consistent thickness is vital for cutting machines, as it enables the machines to be calibrated accurately. Whether it's a thin sheet for intricate die - cut designs or a thick board for sturdy packaging components, the uniformity in thickness ensures that the cutting machine can apply the appropriate amount of force or laser intensity for optimal results.​
