What Is a Plastic Strapping?
Plastic strapping is an extruded thermoplastic band used to bundle, unitize or secure loads to pallets, applied under tension and joined with a heat seal, friction weld or a metal/plastic buckle. Polypropylene (PP) strapping is lower cost with moderate strength and elongation, suited to light and medium-duty bundling, while polyester (PET) strapping has higher tensile strength and much better retained tension over time, making it a common steel-strap replacement on heavier or long-transit loads.
Strapping is specified by width (commonly 1/4 in to 1-1/4 in), gauge (thickness), and break strength, with machine-grade coils wound for automatic or semi-automatic strapping heads and hand-grade coils sized for manual tensioner-and-sealer tools. Coil core diameter must match the dispenser or strapping machine, and seal type (heat-weld, friction-weld, or buckle) should be chosen to match the tensioning tool being used, not swapped freely between systems.

| Spec | What It Means | Why It Matters |
|---|---|---|
| Material | Polypropylene (PP) vs. polyester (PET) | PET holds tension far longer under load and is preferred for heavier or long-duration shipments |
| Width & Gauge | Commonly 3/8 in to 1-1/4 in; 0.02 in to 0.05 in thick | Determines break strength and how much tension the strap can hold before failure |
| Break Strength | Rated in lbs, typically 200-1,600+ lbs | Must exceed the combined load weight and expected shock during transit |
| Coil Grade | Machine grade vs. hand grade | Machine coils are wound for automated feed; hand coils suit manual tensioner-sealer tools |
| Seal/Join Method | Heat seal, friction weld, or wire/plastic buckle | Must match the tensioning tool in use — seals are not interchangeable across tool types |

FAQ
Plastic Strapping Questions, Answered
What's the difference between polypropylene and polyester strapping?
Polypropylene (PP) strapping is lower cost with moderate tensile strength and higher elongation, meaning it stretches more before breaking — suited to light or medium bundling where the load doesn't shift much. Polyester (PET) strapping has higher break strength and, critically, retains tension far better over time, so it doesn't loosen as the load settles during a long truck or ocean transit, which is why it's the standard steel-strap replacement on heavier loads.
How do I choose the right strapping width and break strength?
Break strength should exceed the combined weight of the bundled load plus a safety margin for shock loading during handling and transit — as a starting point, many packagers target a break strength at least 2-3x the load weight per strap applied. Width and gauge scale with break strength: heavier loads need wider, thicker strap, but the width must also fit the strapping head or hand tool being used.
What's the difference between machine grade and hand grade strapping coils?
Machine grade coils are wound with tighter, more consistent tension and sized for automatic or semi-automatic strapping machines that feed and tension the strap mechanically. Hand grade coils are wound for manual tensioner-and-sealer tools operated by hand. The two aren't interchangeable — a hand-grade coil can jam or feed inconsistently in an automated head.
Can I use plastic strapping to replace steel strapping?
In many applications, yes — polyester (PET) strapping is specifically engineered as a steel-strap replacement, offering comparable break strength with better shock absorption, no rust, and a much lower risk of cut injuries during handling. It's not a universal substitute for extremely heavy or sharp-edged loads (like bundled steel coil), where steel strap's higher stiffness is still specified.
What seal or joint type should I use with my strapping?
The seal method must match your tensioning tool: heat-seal and friction-weld tools fuse the strap to itself and require no separate hardware, while manual tensioner-and-sealer combos typically crimp a metal or plastic buckle over the overlapped strap ends. Confirm the seal type your existing tool applies before ordering coils, since switching seal types usually means switching tools as well.
