PP/PS/PE Plastic Sheet Extrusion Line
The PP/PS/PE plastic sheet extrusion machines are engineered to deliver high-quality and precise sheet production for diverse industries. By combining extrusion, calendering, and winding processes, the system converts raw plastic pellets into sheets or roll stock ready for thermoforming. Capable of processing PS, PP, and HIPS polymers, it supports applications such as plastic cups, bowls, trays, blister packs, and stationery packaging. With versatile performance and dependable operation, it provides manufacturers with a reliable solution tailored to meet various production needs.
