Selecting the right type of packaging materials ensures your product reaches its destination intact. This makes it important to understand the differences between steel strapping and polyester strapping properties, to make certain you are using the product best suited to your application.
Most agree that steel strapping is stronger but polyester strapping is more versatile, this means that there are instances when one type of strapping will be better suited than the other.
Your first consideration is to ensure your strapping has the strength to withstand the pressure or forces it will be subjected to during use.
Not only should you consider the load weight and size but also corrosives, moisture and temperature change your load may be exposed to.
Learn more about the differences between steel and polyester strapping below.
Steel strapping is the strongest strapping material, the ultimate choice for heavy loads or sharp-edged material shipments that cannot, or do not need to be compressed.
As steel strapping retains its tension it is ideal for keeping stable loads secure for long periods of time. It is resistant to moisture and extreme temperature changes, and can withstand prolonged exposure to UV light.
However, untreated steel strapping may rust in outdoor environments, leaving stains on your product.
Polyester strapping is a versatile material, a better choice than steel when your package requires being compressed, or when it has the potential to expand, contract, or settle.
This is a way of saying that polyester material is elastic, so it can adjust as your shipment adjusts during transit.
PET strapping is also resistant to corrosives and moisture, it will not stain your product.
Overall, unless you have a large or extra heavy load, or sharp-edged product that requires sturdy metal straps, polyester strapping is the ultimate packaging option. Save on the cost of materials and labor, and increase productivity with longer rolls.
Polyester strap is a recyclable material making it more environmentally friendly, coils are lighter so more user friendly and softer material reduces potential damage to product or injury to the user.
However, there are applications where steel is the most suitable option; though polyester has impressively retained tension compared with polypropylene strapping, unlike steel, over a long period of time, polyester does begin to lose its tension, also unlike steel, its performance degrades with large amounts of UV exposure or extreme temperature changes.
| STRAP TYPE | SUGGESTED USE |
| Polypropylene Strapping | Light – Medium Duty Application |
| Polyester Strapping | Medium – Heavy Duty Application |
| Steel Strapping | Heavy – Extra Heavy Duty Application |
Remember: Strapping is applied using tension, therefore when removing strapping materials use caution, eye protection is recommended.
