Many companies have switched from steel to polyester strapping over the past several years. There are several reasons for this. First, polyester is safer than steel with no sharp edges and it’s also much lighter and easier to handle. When steel prices go up, there seems to be more interest by end-users, to take a look at polyester.
In order to help make an informed decision, here are a few differences to consider:
Steel strapping is sold in coils of various widths, thicknesses and break-strengths. Usually, they are rated as regular duty or high tensile. Each coil weighs approximately 100 lbs., which exceeds the maximum normal lifting limits suggested by experts. Steel is very durable but it can rust and handling it can be a challenge because of its heavy weight and sharp edges. In addition, when the steel strap is cut off of the load, it often “springs back” and precautions need to be taken to prevent injuries to the operator.
Polyester strapping is also sold in coils of various widths, thicknesses and break-strengths. Because it’s strong, yet flexible, it handles heavy loads and won’t break under tension. It will elongate under stress and then, rebound up to 8-10%, keeping a compressible load tight.
Its edges are not sharp and each coil weighs approximately 50 lbs. (½ of a steel coil), which makes it much easier for the operators to change coils on the dispenser carts.
Polyester can be tensioned, sealed and cut, using a battery-operated strapping tool, like the Signode BXT2. This makes the process of strapping quicker, more consistent and safer.
Polyester strap generally saves 30-50% over the current cost of steel strapping. It’s also readily recyclable.
Regardless of the potential savings, your decision must be based on what works. If your product does not arrive undamaged, cost savings don’t matter!
