PET stands for Polyethylene Terephthalate and is a high quality plastic resin in Polyester. 
PET Strapping has a higher tensile strength than PP (Polypropylene) strapping and its characteristics are long life, resistance to ultraviolet light and is weatherproof. 

One of the great advantages is the high elasticity, therefore allowing the strap to maintain its tensile state even if the package shrinks after being strapped up. This advantage has also made PET straps a successful candidate in replacing steel strapping in various applications.
