Polypropylene Strapping Characteristics
Polypropylene is a lightweight and economical type of plastic strapping that is used in many light to medium bundling and palletizing applications. It is one of the most common types of strapping and comes in a range of colors, widths, and thicknesses. Most polypropylene strap is embossed. Embossing adds flexibility, split resistance, and an improved grip to the strapping.
Polypropylene is available in both hand grade and machine grade. It can be applied with hand tools or battery-operated tools and is much safer to use than steel strapping.
All plastic strapping stretches when under tension. This property is called elongation and the strapping’s natural tendency is to recover to its original length. Over time, the strapping will relax and lose its tension. The amount of tension the strapping can hold over time is called retained tension. After a few days, polypropylene strapping’s retained tension drops significantly. Polypropylene has the lowest retained tension out of all the strapping types.
Industries and Applications
Polypropylene strapping is used in a wide variety of industries including:
- Printed materials
Benefits of TEWE Polypropylene Strapping
Not all strapping is created equal, and that’s why at GAPCO we supply TEWE Polypropylene. TEWE is dust-free by design, which increases your machine’s uptime and reduces your downtime due to cleaning out your machines.
TEWE features consistently high quality, high breaking strength, and consistent manufacturing specifications to guarantee a smooth strapping process. It is suited for all semi-automatic and fully automatic strapping machines. Thanks to its advanced embossing techniques, it will run on your machines with close-to-zero abrasion.
Other brands of polypropylene strapping have a lower total yield per coil than TEWE. Improper winding of the coils during manufacturing, such as winding when the polypropylene is still too hot, or winding too tight, can render the last 10-20% of the coil unusable.
