As sustainable packaging demand keeps rising globally, more paper mills and packaging factories are investing in reliable, cost-effective production equipment. The grey board making line has become a core investment for enterprises planning mass production of industrial grey cardboard, rigid box base materials and hardcover book substrate. As a professional paper hardboard production line manufacturer, we continue to upgrade our automated grey board production system to satisfy buyers from Southeast Asia, Africa, the Middle East, South America and Europe. A complete grey board making line is an integrated set of industrial machinery covering raw material feeding, multi-layer laminating, hot pressing, continuous drying, calendering, longitudinal & cross cutting and automatic stacking. Different from single-function grey board making machine, the whole grey board making line realizes fully continuous operation from waste paper input to finished grey board output. Most clients adopt recycled waste paper, carton scraps and waste pulp as raw materials, which greatly lowers raw material cost and meets worldwide eco-friendly production policies.

Core Technical Advantages of Our Grey Board Making Line
The upgraded automatic grey board making line adopts PLC intelligent centralized control system, which stabilizes all key production parameters including tension control, glue dosage, hot pressing temperature and drying speed. Operators can monitor the whole running status on the touch screen, effectively reducing manual errors and cutting labor costs by over 35% compared with semi-automatic equipment.
Stable board qualityThis grey board making line produces grey board with uniform thickness, high stiffness, flat surface and low deformation rate. The finished laminated grey board avoids delamination, warping and uneven density, perfectly matching downstream processes including die-cutting, lamination and rigid box wrapping. The adjustable thickness range covers 1.0mm–5.0mm to satisfy diversified packaging requirements.
Energy-saving & low consumption designEquipped with variable frequency drive and sealed energy-saving drying channel, our automatic paper hardboard production line reduces power consumption significantly. The circulating hot air system improves heat utilization, helping paper manufacturers control long-term operation expenditure. For investors, lower energy loss means better profit margin of finished grey cardboard. Strong raw material adaptabilityThe whole grey board making line supports multiple raw materials: recycled waste paper, mixed paper pulp, carton waste. Clients do not need high-grade virgin pulp, making the equipment highly suitable for newly-built small & medium-sized paper factories in emerging markets.
Flexible customization serviceWe supply customized grey board making line according to customers’ workshop space, target daily output and required board width. Available working widths include 1400mm, 1600mm, 1800mm, 2000mm. Daily production capacity ranges from 15 tons to 60 tons. Whether you need a compact small grey board making line or a large high-speed continuous production line, we can offer tailored layout drawing and technical scheme.
