Polyester (PET) strapping is generally smooth in texture, but can also be embossed. Most Polyester strapping is created from recycled materials.
Heavy-duty polyester strapping has a higher tensile strength than steel and has decent thermal tolerance. It also has a lesser amount of tension decay over PP, which means it holds the tension for a longer period of time. This is important to keep in mind for cross-country hauls from one destination to another, or multiple stops along the path to the load's final destination.
There is also a polyester corded strapping, which is easily tied by hand with a wire buckle. It is a cloth material glued together, so there is no stretch available, but it is very flexible.
There are new formulations available as well such as Dynaric/PolyChem's Ultraband polyester strapping which can handle weighty loads, up to 2000 lbs of tensile strength. This strapping does have a higher price point though.
Polyester strapping is best used for rigid loads and helps to absorb impact during transit. It's also a better alternative when you need higher initial tension to contain loads when compared to PP strapping.
