Straps snapping or loads shifting? Poly, PET or Steel: pick the right one

A strong alternative: polywoven strapping

Where a load needs high strength but steel keeps snapping on shock or scratching surfaces, polywoven strapping is worth a look. Woven from polyester yarn, it carries a high break strength with the safety and corrosion resistance of a plastic strap, and it has enough give to absorb movement without failing. It is a common pick for furniture, machinery and other heavy or awkward loads.

Get the tension and tools right too

The strap is only half the system. A weak seal or joint fails just like a snapped strap, and the wrong tool cannot reach the tension the load needs. Match the tensioner, sealer and seals to the strap material and width, since poly, PET and steel each need their own. The full strapping range includes the tools and seals that go with each material, so the joint is as strong as the strap.

Load restraint and chain of responsibility

Under Australia’s Chain of Responsibility provisions in the Heavy Vehicle National Law, every party in the supply chain shares legal accountability for loads being safely restrained for road transport, and that includes the businesses that pack and strap them. A strap that snaps or a load that shifts is both a safety risk and a compliance one. Choosing a strap with adequate break strength and the right tension behaviour, then applying it correctly, is part of meeting that duty. For palletised loads, strapping works alongside pallet wrap and stretch film for full load security.

How Premium Packaging helps you fix strapping failures

Premium Packaging is a Sydney-based wholesale supplier stocking poly, PET, steel and polywoven strapping, along with the tensioners, sealers, seals and dispensers that go with each. Our specialists look at what is failing and why, then match the strap material, width and break strength to your loads and freight lanes, so the next run holds.

Stock is held at our Werrington warehouse with delivery across Sydney, Melbourne, Brisbane, Adelaide, Perth and regional Australia, and recurring supply keeps your packing lines running as volumes grow.

Frequently asked questions

Why do my pallet straps keep snapping?

Usually the strap is too weak for the load, over-tensioned, or being cut by sharp edges. Step up to a stronger material such as PET, set the correct tension with the right tool, and fit edge protection on sharp corners.

Why do my loads keep shifting even though the straps hold?

The strap is likely losing tension. Poly stretches and does not recover, so on heavy or settling loads it slackens. PET recovers its tension after stretching, which keeps settling loads secure through transit.

Is PET strapping stronger than poly?

Yes. PET has a much higher break strength and, unlike poly, recovers its tension after the load settles or is jolted. It is the usual step up when poly straps snap or loosen on heavier loads.

When should I use steel instead of PET?

Steel suits very heavy, rigid loads that do not settle, such as metal or timber packs. If the load settles or compresses, steel goes slack because it has no give, so PET holds better on those loads.

Does strapping tension affect whether straps snap?

Yes. Too little tension lets loads shift, while too much can snap the strap or crush the load. Matching the tension and material to the load, and using the correct tool, prevents both failures.
