Polyester retains tension longer than polypropylene and has a more “elastic” effect of keeping shrinking packages tighter. Polyester is also being made to handle heavier loads once only thought to be capable of steel strapping. Polypropylene is used for light and heavy bundling and light palletizing/unitizing application. Polyester is only used for palletizing/unitizing on the heaviest load or loads that shrink or shift significantly.
