Polypropylene Strapping is the most commonly used and least expensive of all strapping materials. It's light and easy to apply and recycle. This Machine Grade Strapping is perfect for bundling, packaging, sealing or securing your products, boxes or objects. Poly strapping is available in both hand grade and machine grade and can be sealed with buckles, seals, heat seals, or with a friction weld strapping tool. Use poly strapping for light duty palletizing, unitizing, carton closing, and bundling. It is used in all semi-automatic strappers and nearly all stand alone arch machines.
