Signode Tenax (line)

Polyester strapping combines strong load containment, shock absorption, and corrosion resistance for securing palletized shipments.

Not for: Hot loads, unprotected sharp-edged bundles, or applications specifically requiring steel strapping.

Strap material. Use polypropylene for light bundling, polyester (PET) for heavy pallets, and steel for very heavy or high-temperature loads. Polypropylene stretches and relaxes under load. PET holds tension close to steel.
Break strength. Match the stated break strength to the load, with a safety margin. Do not choose by width alone. Straps of the same width vary widely in strength depending on material and thickness.
Width and thickness compatibility. Seals, buckles and tensioners must be rated for the exact strap width and thickness, such as 1/2 inch or 5/8 inch. Mismatched seals slip, and the joint fails before the strap does.
Core size. Check the coil core size against your strapping cart or dispenser. Coils on the wrong core will not mount on the dispenser.
