What is the difference between polyester and polypropylene strapping?
Polyester strapping is much better at retaining any applied tension over long periods and is less susceptible to tension relaxation caused by increases in ambient temperatures. Polyester strapping also offers higher recovery characteristics and stays tighter than polypropylene strapping on packs that shrink or become compressed. UV resistance is also improved hence its popularity on product stored outside such as building materials. Nevertheless, polypropylene strapping is suitable and more cost effective for the majority of applications.
