The specifications of PET (Polyester) Strapping Band vary depending on the application (light, medium, or heavy-duty packaging). Below are the key technical parameters and common specifications:
1. Material & Properties
- Material: Polyethylene Terephthalate (PET)
- Elongation: 2% – 3% (low stretch, excellent for load stability)
- Tensile Strength: 300 MPa – 800 MPa (stronger than PP & steel strapping in some cases)
- Working Temperature: -40°C to +85°C (heat-resistant, suitable for harsh conditions)
- UV Resistance: Excellent (suitable for outdoor storage)
- Moisture Resistance: Waterproof, does not rust or corrode
- Recyclable: Eco-friendly, can be reused
2. Common Sizes (Width & Thickness)
| Width (mm/inch) | Thickness (mm) | Breaking Strength (kN) | Typical Use |
|---|---|---|---|
| 9 mm (3/8″) | 0.6 – 0.8 mm | 2.5 – 4.0 kN | Light packaging, cartons |
| 12 mm (1/2″) | 0.7 – 1.0 mm | 3.5 – 6.0 kN | Medium-duty bundling |
| 15 mm (5/8″) | 0.8 – 1.2 mm | 5.0 – 8.0 kN | Heavy pallets, bricks |
| 19 mm (3/4″) | 1.0 – 1.5 mm | 7.0 – 12.0 kN | Steel coils, timber, construction |
| 25 mm (1″) | 1.2 – 1.8 mm | 10.0 – 20.0 kN | Extreme heavy-duty loads |
3. Color Options
- Standard: Black, Green, White, Transparent
- Custom: Available in various colors (e.g., blue, red, yellow) for coding or branding
4. Packaging & Roll Length
- Roll Length: Typically 500m, 1000m, or custom lengths
- Core Diameter: 200mm, 300mm (standard)
- Weight per Roll: Depends on width & thickness (e.g., 12mm x 1000m ≈ 8-12 kg)
5. Jointing Methods
- Sealing Tools: Heat fusion (most common), metal or plastic seals, buckle locks
- Compatible Tools: Manual tensioners, pneumatic strapping tools, automatic machines
6. Key Advantages vs. Other Strapping Types
| Feature | PET Strapping | PP Strapping | Steel Strapping |
|---|---|---|---|
| Strength | High (300-800 MPa) | Medium (200-400 MPa) | Very High (600-1000 MPa) |
| Elongation | Low (2-3%) | High (10-25%) | Very Low (<1%) |
| Weight | Light | Very Light | Heavy |
| Corrosion | No | No | Yes (rusts) |
| Cost | Moderate | Low | High |
7. Common Applications
✔ Logistics & Shipping (carton sealing, pallet bundling)
✔ Construction (bricks, timber, rebar)
✔ Metal & Paper Industries (steel coils, paper rolls)
✔ Agriculture (hay bales, fertilizer bags)
✔ Export Packaging (moisture-proof, durable)
