PET vs. PP Strap Making Machine: Key Differences & Uses
In the packaging industry, PET (Polyethylene Terephthalate) and PP (Polypropylene) strap making machines are core equipment for producing packaging straps. This guide breaks down technical differences, equipment specs, and ideal applications—helping you select the right system for your business.
1. Key Differences Between PET and PP Strap Making Machines
To choose the right strapping production line, understanding their fundamental differences is critical. Below is a detailed comparison from three core dimensions:
1.1 Technical Parameters Comparison
Technical specs like output, extruder size, and production speed distinguish the two machines, reflecting their capacity for different production demands.
Parameter | (Xindacheng) | (Xindacheng) |
Max Output | 900 kg/h(heavy-duty) | 350 kg/h |
| Extruder Size | Φ90-150mm | Φ75-150mm |
| Strap Width | 9-32mm (wide for heavy loads) | 5-19mm (narrow for lightweight) |
| Production Speed | 160m/min | 210m/min |
| Strap Lines | 1-12straps | 1-8stras |
1.2 Equipment Configuration
PET Machines: Require crystallizing dryer (for moisture control), back-flush screen changer (non-stop filtration), and heat stretching oven (for strength).
PP Machines: Simplified design—no dryer needed, integrated touchscreen control, and optimized for PP’s flexibility.
1.3 Material Compatibility
PET Machines: Process 100% recycled materials (e.g., PET bottles) and virgin PET. Ideal for eco-friendly production.
PP Machines: Best for virgin PP resin (drawing-grade), offering smooth extrusion for flexible straps.
2. Uses of PET and PP Strap Making Machines
Their differences in strength, weight, and cost make them suitable for distinct packaging scenarios.
2.1 PET Strap Making Machine Applications
PET straps (also called “plastic steel bands”) are high-strength alternatives to steel belts, making the machines ideal for heavy-duty packaging in industries such as:
Steel, aluminum ingot, and chemical fiber (for bundling large, heavy metal/chemical products).
Paper, brick ceramics, and wood (for securing bulk materials during transportation).
Tobacco, electronics, and textiles (for high-demand packaging that requires corrosion resistance and stability).
Eco-models (max output 200 kg/h) are perfect for small-to-medium enterprises with limited initial investment, while heavy models (up to 900 kg/h) cater to large-scale industrial production.
2.2 PP Strap Making Machine Applications
PP straps excel in lightweight, flexible packaging due to their low density, easy usability, and good tensile strength. The machines are widely used for:
Bundling cartons, small appliances, and daily necessities (low-cost and easy to operate).
Packaging non-heavy goods in logistics, food, and retail industries (low waste and high production speed up to 210 m/min).
Small-batch or multi-variety production (supports 1-8 straps/line, adapting to diverse order needs).
