A clear, practical guide to the types, strengths, and best uses of industrial strapping, so you can secure your goods safely, efficiently, and with confidence.
When it comes to industrial packaging and load securing, strapping might not get the spotlight, but it’s the backbone of a safe, efficient supply chain. The right strap ensures your goods stay stable, protected, and arrive exactly as they should, no shifting, no damage, no surprises.
Whether you’re bundling small cartons or locking down tonnes of steel, there’s a strapping solution built for the job. This guide will walk you through the main types, their strengths, ideal uses, and how to choose the best one for your operation.

*Break strain = maximum load a strap can withstand before breaking.
1. Polypropylene (Poly) - The Everyday Workhorse
If you need a cost-effective, lightweight, and versatile solution, poly strapping delivers. It’s the go-to for everyday packaging tasks.
Best for: General packaging, securing cartons, palletising light goods.
Widths: 5–19 mm (available in blue, clear, and other colours)
Break Strain: 90-150 kg
Formats:
-
Hand rolls (~1,000 m) for manual application.
-
Machine rolls (e.g., 12 mm × 3,000 m) for automatic systems.
Sealing options: 90-150 kg
-
Poly or wire buckles (manual)
-
Tensioner + metal open seals (crimped)
-
Heat weld (automatic machines)
Pro tip: If you want speed and efficiency, pair poly strapping with an automatic heat-weld machine.
2. Heavy Band Poly - Extra Strength Without the Bulk
When standard poly isn’t quite enough, heavy band black poly steps up. It’s stronger, yet still easy to handle.
Widths: 15 mm & 19 mm.
Strength: Higher than standard poly.
Best for: Heavier goods that still benefit from user-friendly application.
3. Steel Strapping - The Heavy-Duty Classic
Steel remains the gold standard for maximum rigidity and extreme load security.
Widths: 12 - 32 mm.
Roll types:
-
Ribbon wound (compact for dispenser frames).
-
Mill wound (45-50 kg rolls for wheeled carts).
Seal types: Snap-on or pusher seals.
Safety warning: Always wear safety glasses and cut-resistant gloves. Steel edges are sharp and can recoil unexpectedly.
4. PET Polyester - The Safer Steel Alternative
PET strapping is taking over where steel once ruled, offering comparable strength without the handling hazards.
Widths: 9–25 mm+ (smooth or embossed).
Break Strain: 400–800 kg.
Advantages:
-
Almost as strong as steel, safer to work with.
-
No rust.
-
Perfect for timber, steel, and scaffold pallets.
Application methods:
-
Tensioner + steel seals (dimpled for grip).
-
Cordless battery tools (tension and heat weld in one) up to ~150 straps per battery charge.
Maintenance tip: Invest in quality tools (Swiss-made options last longer) and service them every six months for heavy use.
5. Webbing & Composite – Flexible, Tough, and Reusable
Webbing: Woven polyester, seatbelt-like in texture.
Composite: Polyester fibres encased in a protective coating.
Strength: High with excellent flexibility.
Best for: Outdoor loads, irregular shapes, reusable securing.
Application: Heavy-duty wire buckles + manual tensioning tools.
How to Choose the Right Strapping
Load Weight & Type: Match the break strain to your load’s demands.
Environment: Will it face rain, sun, moisture, or rough handling?
Safety: Steel is strong but risky; PET offers similar performance with fewer hazards.
If you want heavy-duty performance, safety, and efficiency, PET polyester is often the best choice. Still, each strapping type has its place, selecting the right one ensures your products travel from point A to point B securely, every single time.
