Polypropylene strapping is the most commonly used and least expensive of all strapping materials. It's light and easy to apply and recycle. Poly Strapping characteristics include high elongation and recovery, but low retained tension. Polypropylene strapping is available in both manual and machine grade and can be sealed with buckles, seals, heat seals, or friction welds.
Polypropylene strapping is an excellent choice for light duty palletizing, unitizing, carton closing, and bundling. It is used in all semi-automatic strappers and nearly all stand alone arch machines.
Some things to look for in a strapping machine are Minimize Packaging Time,
Secure Contents Effectively, User Friendly Controls, Stainless Steel Strapping Surface, Portable for Convenience and Easy Access for Reloading Strapping.
There are many accessories for strapping machines including strapping cutters, strapping dispensers, strapping edge protectors and strapping kits.
Strapping kits typically include a steel strapping tensioner, a strapping cart for steel strapping, a steel strap cutter and a steel strapping sealer.
Steel strapping is the strongest of all strapping materials. It is recommended where high strength is necessary, low elongation is important, and where the product is extremely sharp or hot. Steel strapping is sealed using mechanical seals and notch strapping seals (sealless) type joints. Although the market for steel is declining, there are numerous applications where steel is the preferred alternative.
