Plastic pp Corrugated Hollow Sheet Machine pp Packing Box Making Machine Plastic pp Hollow Board Production Line

This complete extrusion equipment for PP hollow core sheets (plastic hollow sheets) uses modified PP particles and recycled PP as raw materials. It employs single/double layer co-extrusion with a dedicated hollow mesh die to form double-layer hollow sheets with central connecting ribs in one step. By changing the die, it can produce 2–12mm standard hollow sheets with widths covering 1200–2400mm. The entire line is PLC-synchronized and linked for automated continuous mass production. It is widely used in packaging, warehousing, advertising, and electronic protective sheet production.
