Strapping, in general, is the most common means of packaging, bundling, and storing in the packaging, logistics, and delivery industries. There are many types of strapping products available. PET Strap, or polythene terephthalate material strapping, is just one of these products and is one of the most durable and most proven strapping materials.

PET straps are used for situations such as:

  • Bundling together for handling and shipping such as concrete blocks, lumber, pipes, newspapers, etc.
  • Reinforcing corrugated boxes, crates, wooden boxes, etc.
  • Attachment of items to tractor-trailers, flatbeds, and flatcars.
  • Securing load units of metal parts, packaged glass, bricks, etc.
  • Closing and sealing shipping containers and corrugated boxes.
  • Securing coils of paper or steel.
  • Holding bales of textiles or agricultural products.
  • Securing item loads inside tractor-trailers, boxcars, and intermodal containers.

 

PET strapping is often used in full vertical and horizontal bands. Also, edge protectors are used to help spread the PET strap’s tension on the load at corners and reduce damage caused by tension due to travelling. PET strapping can also be used in loops attached to permanent tie-down points. This is prevalent with skids, tractor-trailers, and rail cars.

 

The unfortunate use of ropes

Rope, rope strapping, and other hemp-based yarns are some of the oldest strapping methods used in securing shipping goods up to the middle of the 20th century before being slowly replaced by steel straps. Unfortunately, in many countries, ropes and its variants are still used in a variety of ways. While ropes are very low-cost compared to PET straps, ropes don’t have the same tensile strength, durability, and high-to-minimal stretch as PET straps. Also, it has already been proven time and time again that ropes cannot hold unevenly shaped equipment and materials.

 

The elongation and tension of PET strapping

Unfortunately, ropes are still used in the 21st century. While ropes are still useful for some packaging or shipping purposes, in terms of heavy loads, PET strapping beats ropes every time. PET strapping elongates under tension and then recovers that elongation as stress is relieved. Elongation recovery enables the straps to contract when the package or load shrinks after contraction. All forms of rope may elongate up to 100%, but has almost zero recovery. This means that ropes that elongate become loose.

 

Plastic strapping such as polywoven and PET may vary in their capacity to elongate and recover. When choosing PET strapping, you need to ask these questions based on the loads you are moving or storing:

  • How much elongation recovery is required, especially if the load will shrink?
  • How much tension can be pulled on the PET strap without damaging the load?
  • How much creeping or retained tension is needed?
