PLC Control Plastic Strap Production Line Automatic PP Strapping Roll Making Machine

The conventional PP Strapping Band Extrusion Line is a fully automatic continuous extrusion production system specially designed for manufacturing high-strength polypropylene packing straps. Widely adopted in commodity packaging, logistics transportation and industrial bundling fields, this equipment realizes precise dimensional control and stable consistent quality of finished strapping products.

This production line is equipped with a high-efficiency single-screw extruder with customized screw and barrel structure, which achieves thorough plasticization and melting of PP raw materials. The complete unit is composed of automatic feeding system, extrusion die head, water cooling tank, drying device, preheating & stretching unit, embossing machine and multi-station automatic winding machines. The whole production process is interlocked and synchronized under unified PLC touch screen control, guaranteeing stable operation and high continuous production efficiency.

It supports processing both brand-new virgin PP granules and recycled PP reprocessed materials, and color masterbatch can be added to produce straps with customized colors. The finished PP strap width ranges from 5mm to 19mm, with adjustable thickness between 0.3mm and 1.3mm, which can satisfy diversified bundling demands of multiple 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
