When it comes to securing heavy loads for shipping or storage, strapping materials play a critical role in ensuring safety, stability, and cost-efficiency. Among the most widely used are PET (Polyester) strapping and steel strapping—but which one is right for your business?
In this article, we’ll explore a detailed comparison between PET and steel strapping, covering their strength, safety, cost, environmental impact, and application scenarios to help you make an informed decision.
✅ What is PET Strapping?
PET strapping (Polyethylene Terephthalate) is a thermoplastic polymer strap used primarily in industrial packaging. It is known for its high tensile strength, elasticity, and resistance to UV and weather conditions.

✅ What is Steel Strapping?
Steel strapping is made from cold-rolled steel and is commonly used in heavy-duty load securing, especially where rigidity and minimal elongation are required. It is strong and resistant to cutting, but it comes with a higher risk of injury and corrosion.
Side-by-Side Comparison: PET vs. Steel Strapping
| Feature | PET Strapping | Steel Strapping |
|---|---|---|
| Tensile Strength | High (up to 9500N) | Very High (up to 12000N) |
| Shock Absorption | Excellent – absorbs impact | Poor – rigid and brittle |
| Elongation | Up to 12% – flexible | <1% – minimal stretch |
| Corrosion Resistance | 100% Rust-Free | Prone to rust |
| Weight | Lightweight | Heavy |
| Safety | No sharp edges, safe to handle | Sharp edges, injury risk |
| Environmental Impact | Recyclable, RoHS compliant | Difficult to recycle, higher carbon footprint |
| Cost | Lower material and handling costs | Higher cost due to material and injury risks |
| Machinery Compatibility | Works with battery, friction weld, semi-auto machines | Often needs pneumatic or manual tensioners |
💡 Application Scenarios
When to Use PET Strapping:
- Palletizing boxes, cans, or bricks
- Securing timber, plastic pipes, or printed materials
- Outdoor storage and export packaging
- Companies focused on safety and sustainability
When to Use Steel Strapping:
- Heavy-duty items with sharp edges
- Hot or high-temperature environments
- Products that do not tolerate elongation
- Specific industries like metal production or railway equipment
🔒 Safety & Handling: A Major Difference
One of the biggest advantages of PET over steel is worker safety. Steel strapping has sharp edges and can snap under tension, posing serious injury risks. PET strapping is safe to handle, flexible, and does not recoil dangerously when cut.
According to OSHA guidelines, businesses are encouraged to use safer strapping alternatives to reduce workplace injuries.
🌱 Environmental Impact
PET strapping is 100% recyclable and can be reused in production with minimal processing. It also meets RoHS and REACH standards, helping companies comply with global environmental regulations.
Steel, while recyclable, requires more energy to process, making it less sustainable in the long run.
💰 Cost Comparison
While steel strapping may offer slightly higher tensile strength, PET strapping typically costs 20–40% less in terms of material, equipment, and labor. Add in fewer injuries and easier handling, and the long-term savings become clear.
🏁 Conclusion: PET or Steel?
| Need | Best Choice |
|---|---|
| Maximum strength, no elongation | Steel Strapping |
| Safety, flexibility, sustainability | PET Strapping |
| Export packaging and high-volume use | PET Strapping |
| Corrosive or outdoor environments | PET Strapping |
