Stone plastic paper corrugated hollow sheet making machine (also known as multi-panel production line, honeycomb panel production line, grid panel production line, or double-wall panel production line) is a high-performance extrusion line engineered to produce lightweight, durable stone plastic paper hollow (corrugated/twin-wall) sheets for packaging, logistics, and construction industries.

Our stone plastic paper corrugated hollow sheet making machine is equipped with advanced intelligent control systems and energy-saving extrusion technology. It delivers stable output of 10–12 tons per day while cutting energy consumption by 30% and labor costs by over 50%. Designed for stone powder + PP + additive mixtures (no pelletizing required), our machine streamlines production, reduces costs, and ensures consistent sheet quality with rich color options. It integrates permanent magnet motors, edge material recycling systems, and PLC smart control for fully automated operation, making it ideal for manufacturers seeking efficient, eco-friendly solutions to meet global demand for sustainable packaging materials.

• Handern Machinery's new 5th-generation stone plastic paper corrugated hollow sheet making machine incorporates intelligent control, enables data visualization, and supports direct operation via a mobile APP.
• The filling ratio has been increased from the original "PP + calcium carbonate" at 60% to "PP + phosphogypsum" at 70%, reducing the input cost of PP raw materials – perfect for stone plastic paper hollow sheet production.
• The globally first-invented one-step hollow sheet manufacturing process eliminates the need for pelletizing, enabling direct production of stone plastic paper sheets. It also shortens the length of the machine and reduces the floor space of the plant.
• Provide a complete production line for environmentally friendly and moisture-proof stone plastic paper hollow sheet packaging boxes, along with one-stop solutions, to help start-ups avoid detours.
