POLYESTER (PET) & POLYPROPYLENE (PPY) STRAPPING
Product Overview & Material Selection
For high-capacity B2B logistics, selecting the correct strapping material is a critical decision that prevents transit failures, material shifting, and warehouse safety incidents. At Champion Strapping, we manufacture ASTM-compliant, American-made polymer strapping options tailored to specific environment- and load-specific requirements.
- Polyester (PET) Strapping — The High-Strength Steel Alternative: Polyester strapping is engineered for heavy, rigid, or expanding loads. It is highly resilient, maintaining its tension over time far better than polypropylene. Crucially, PET possesses high elongation recovery, allowing it to stretch under sudden transit impacts (such as railcar coupling or truck braking) and return to its original tension without snapping. It is lightweight, rustproof, and highly resistant to UV degradation and extreme weather conditions.
- Polypropylene (PPY) Strapping — The Flexible, Cost-Effective Standard: Polypropylene is lightweight, flexible, and exceptionally cost-effective. It is primarily recommended for light-to-medium palletizing, carton bundling, and securing unitized packages. PPY strapping features an embossed surface to optimize tensioning and mechanical joint grip, and it offers excellent resistance to moisture, humidity, and chemical exposure in clean warehouse environments.

SEALS & BUCKLES FOR PLASTIC STRAPPING
Selecting the appropriate joint mechanism ensures that the strapping retains maximum parent material strength. We offer both premium galvanized seals and heavy-duty buckles.
- Galvanized Open & Open Serrated Seals: Specifically designed to provide superior mechanical grip. Serrated seals feature internal teeth that lock into polyester strapping, preventing joint slippage under high tension.
- Heavy-Duty Buckles: Designed for tool-less or minimal-tool manual applications, perfect for lighter loads or re-tensioning loads that settle in transit.

Technical FAQ
Material Physics & Load Constraints
- Q: How does Polyester (PET) strapping compare to steel strapping in terms of load tension retention?
- A: Polyester strapping is engineered to deliver performance closely comparable to steel strapping but with several added benefits, including lower weight, easier handling, and complete rust resistance. While steel provides maximum tension with minimal stretch, polyester offers superior elongation recovery. This means if your load settles, contracts, or shifts slightly during transit, the PET strap will contract back to its original tension and remain secure, whereas steel can occasionally become loose on shrinking loads.

- Q: Will plastic strapping degrade or become brittle if pallets are stored outdoors or in extreme environments?
- A: Polyester (PET) strapping features outstanding weatherability and resistance to UV radiation, making it ideal for outdoor storage and hot, humid conditions. In contrast, Polypropylene (PPY) is more susceptible to UV degradation over prolonged exposure and is strictly recommended for clean, indoor warehouse settings PPY also features excellent moisture and chemical resistance but excels primarily in stable, temperature-controlled environments.

- Q: Which plastic strapping is best suited for expanding loads like lumber?
- A: Polyester (PET) is the ideal choice. Because lumber is an organic material that absorbs moisture and expands, or dries out and contracts, the strapping must expand and contract with it. PET’s high elasticity and elongation recovery ensure that the banding moves with the load, absorbing transit shocks without snapping or losing its hold.
Tooling & Hardware Compatibility
- Q: Can I use battery-powered friction weld tools with both PPY and PET strapping?
- A: Yes. High-speed battery combo tools like the P329 are fully compatible with both polyester and polypropylene strapping (sizes 5/8″ to 3/4″). These tools use friction welding to melt the polymer layers together, creating a highly secure, sealless joint that eliminates the need for steel seals or manual sealers.

- Q: When should I use wire buckles instead of galvanized steel seals?
- A: Wire buckles (like our POLY-12WB and POLY-58WB) are recommended for light-to-medium manual applications where strapping tools are minimal or not available. Buckles permit easy manual tensioning and are ideal for loads that require re-tensioning over time. For heavy-duty, high-impact shipping where maximum joint strength is required, we recommend galvanized open or serrated seals used in conjunction with a manual or pneumatic sealer.

- Q: What is the core size of your plastic strapping, and will it fit my existing dispensers?
- A: Our polyester strapping is manufactured on standard 16″ x 6″ cores, making it fully compatible with standard mobile carts such as the DSP-STD. Our polypropylene strapping is available in a variety of core sizes, including 8″ x 7″, 9″ x 8″, 8″ x 8″, and 16″ x 6″, allowing you to match the coils precisely to your current packaging equipment.
Safety & Procurement
- Q: Are there pallet-quantity minimums or volume discounts available?
- A: Our standard packaging consists of 28 coils per pallet for Polyester strapping and 24 coils per pallet for Polypropylene strapping. While some items may require a minimum order quantity (MOQ), we provide aggressive volume discounts for pallet-quantity and truckload-quantity orders. Contact your Champion Strapping representative to discuss custom shipping schedules and contract pricing.

- Q: Is plastic strapping safer for warehouse personnel to apply and remove than steel?
- A: Yes, plastic strapping is significantly lighter than steel, which reduces worker fatigue and minimizes the risk of lifting injuries. Furthermore, during removal, plastic strapping does not contain the same high kinetic energy as steel strapping, drastically reducing the danger of whip-back injuries when the bands are cut. However, operators should always wear safety glasses and cut-resistant gloves during application and removal.
