A practical guide to selecting the right strapping material and banding tools for shipping, warehousing, and industrial packaging.
Packaging straps keep shipments secure from warehouse to destination. Choosing the wrong material or tool leads to damaged goods, failed loads, and costly returns. Here's what actually matters.
The most affordable and widely used option for light-to-medium duty packaging. PP strapping is lightweight, easy to apply, and works well for bundling boxes, securing pallets of lighter goods, and general warehouse use. It has moderate elongation, which helps absorb shock during transit. Downside: it degrades under UV exposure and isn't suitable for heavy loads.
The plastic alternative to steel strapping. PET offers high tensile strength, low elongation, and excellent retained tension — meaning it stays tight even as loads settle. Best for heavy pallets, unitizing loads, and applications where steel strapping is overkill. More expensive than PP but significantly stronger.
The highest-strength option. Steel strapping is used for extremely heavy loads, sharp-edged products, and applications where retained tension is critical. It doesn't elongate, which is ideal for rigid loads. Requires more care to handle safely — cut ends are sharp. Heavier and more expensive than plastic alternatives.
A good strapping tensioner tool makes the difference between a secure load and a loose one. Manual tensioners work for occasional use; pneumatic or battery-powered tools are worth the investment for high-volume operations. Match your tool to your strapping material — PP and PET tensioners differ from steel strapping tools.
Open seals (also called clips) are the standard for most plastic strapping. Closed seals offer higher strength. For steel strapping, use steel seals only. Never mix seal types with incompatible strapping materials — it's a common cause of joint failure.
