Our line for PP hollow sheet (also known as multi-panel, honeycomb, grid, or double-wall line) is a high-performance extrusion system engineered to produce lightweight, durable twin-wall sheets for packaging, logistics, and construction.

Equipped with intelligent controls and energy-saving technology, the production line for PP hollow sheet delivers stable 10–12 tons/day output, cuts energy consumption by 30%, and reduces labor costs by over 50%. It supports direct extrusion from stone powder + PP + additives — no pelletizing required — streamlining production, lowering costs, and offering rich color options. Key features include permanent magnet motors, an edge recycling system, and PLC smart control for fully automated operation.

• Higher filler ratio: Up to 70% filler (PP + phosphogypsum) reduces raw material cost — ideal for PP hollow sheet.
• One-step process: Eliminates pelletizing, cuts line length, and saves factory space.
• Eco-friendly packaging solution: Complete line for moisture-proof, recyclable hollow sheet boxes; one-stop service for startups.
