Polyester is the strongest plastic strap. It is often used for heavy loads that require a high tension during handling, transport and storage. PET straps offer high tension, are able to retain this tension for a long period of time and have an excellent stretch recovery. Because of the stretch recovery, they are excellently resistant to shocks and impacts. PET strap is light, UV resistant, recyclable and easy to handle. These properties remain, even at high temperatures. The main disadvantages is that it is less elastic than PP strap.
