The conventional PP Strapping Band Extrusion Line is a full-automatic continuous extrusion system engineered to produce high-strength polypropylene packing straps. Popularly utilized for commodity packaging, logistics transport and industrial bundling, the equipment delivers precise dimension control and stable, uniform quality for finished straps.

Fitted with a high-efficiency single-screw extruder built with customized screw and barrel, the line enables complete plasticization and melting of PP raw materials. The full set consists of automatic feeding system, extrusion die head, water cooling tank, drying equipment, preheating & stretching unit, embossing machine and multi-station automatic winders. Unified PLC touch screen control realizes interlock and synchronization of all procedures, ensuring stable operation and efficient continuous production.

Production supports virgin PP granules as well as recycled PP materials. Color masterbatch can be supplemented to manufacture straps in custom colors. Finished PP strap width ranges 5mm–19mm and thickness is adjustable from 0.3mm to 1.3mm, meeting various bundling requirements across numerous industries.

1. Fully automatic integrated single-screw extrusion forming production line
2. Optimized screw & barrel design to improve PP raw material plasticization efficiency
3. PLC centralized intelligent control to realize synchronous linkage of all production sections
4. Compatible with virgin PP pellets, recycled PP materials and color masterbatch for flexible production
5. Complete closed-loop production workflow: Feeding → Extrusion → Water Cooling → Drying → Stretching → Embossing → Auto Winding
6. Capable of producing 2~4 strips of packing strap simultaneously, with high hourly output
7. Strap width and thickness are adjustable to switch between different product specifications quickly
8. Low failure rate, simple operation and convenient daily maintenance

• Feeder: Automatic lifting feeding for recycled materials, virgin PP particles and color masterbatch
• Extruder & Die Head: Core melting extrusion unit to shape initial PP strap blank
• Cooling & Drying Tank: Rapid water cooling and follow-up drying to fix strap shape and remove surface moisture
• Preheating & Stretching Machine: Tensile forming to enhance the tensile strength of finished packing strap
• Embossing Device: Press anti-slip patterns on strap surface to increase friction during bundling
• PLC Control Cabinet: Parameter setting, real-time monitoring and whole-line operation control
• Automatic Winder: Auto rolling and forming of finished straps into standard finished rolls
