Our company major in all kinds of PP hollow corrugated sheet making machine. 

We have the machines for the PP hollow grid plate width from 1200mm to 2400mm and thickness from 2mm to 12mm. We have different model production line,such as the 1400 type PP hollow sheet extruder machine, 1800 type PP corrugated panel extrusion line, 2400 type PP hollow corrugated board making machine, And for each model,we have co-extrusion type for customer choose. The co-extruder type can use 20%-60% filler match for reduce the cost, so our customer can produce the cost competitiveness sheet with good quality.

PP/PE hollow sheet is light and high strength, moisture-proof, good environmental protection and re-fabrication performance and can be used into the reusable container, packing case, clapboard, backing plate.
