You have just purchased a manual PP strapping tensioner and need to use it correctly from the very first box: apply just enough tension so that the package is firm, without applying too much force (which would break the polypropylene) or too little (the pallet would arrive loose at its destination). This guide covers the complete procedure for using this tool, from strap preparation to sealing and final verification.

Before operating the tool, it is advisable to have the exact technical data clear to confirm that the PP strapping you are going to use falls within the working range of the tensioner.

Step-by-step Usage Guide
The complete procedure combines four elements: the PP strap, the tensioner, the closure system (seal + sealer or plastic buckle), and the package you are securing. Follow the steps in order: the final result depends on maintaining tension during closure, not just on applying it.
Prepare the strap and wrap it around the package
Unroll the PP strap from the coil, leaving an excess of about 30 cm more than the package's perimeter. Pass the strap under the pallet or around the box until both ends meet on the top surface. Avoid twisting: the strap should lie flat against the package surface throughout its path.
Place the closure system over the two ends
If closing with a metal seal, slide the seal over the two overlapping strap layers, leaving approximately 5 cm of free strap above the seal for the tensioner to grip the excess. If closing with a plastic buckle, pass the first end of the strap through the buckle, fold it back, and leave the second end ready to insert after tensioning.
Insert the strap into the tensioner
Place the tensioner on the top surface of the package, next to the seal or buckle. Insert the free end of the strap into the tensioner's slot following the direction indicated by the mechanism. Make sure the strap is securely held between the serrated wheel and the base before beginning to tension.
Operate the lever to apply tension
Move the lever back and forth rhythmically. Each movement advances the mechanism and progressively tensions the strap. Do not force the lever: polypropylene has a low elastic limit and will break if overtensioned. Stop when the strap is firm against the package and you feel clear resistance in the lever.
The correct tension of PP strapping can be felt by touch: the strap should be firm against the package and, when pressed with a finger, it should barely give way. If it vibrates like a guitar string, it is overtensioned and will break in transit; if it sinks with your finger, it is loose and the pallet will fall apart at the first movement. Calibrate with two or three test pallets before starting serial strapping.
Close the system without losing tension
Keeping the tensioner firm to maintain tension, proceed with the closure: if working with a metal seal, apply the manual sealer over the seal to close it (see the sealer guide); if working with a plastic buckle, fold the second end of the strap back into the buckle. Only then release the tensioner and cut the excess strap.
Doubts about compatibility with your strap?
If you are unsure whether the width of your PP strap falls within the tensioner's range, or if you don't know how many turns to make around the package based on its load, ask the virtual assistant. It resolves technical and compatibility questions without delay.
Complementary Products
The tensioner is the tensioning tool, but it does not operate alone: complete strapping requires PP strap, a closure system, and, optionally, a sealer for metal seals. These are the products that accompany it in any manual polypropylene strapping operation.
PP strapping is the main consumable, available in 13 mm × 1,300 m and 16 mm × 900 m (both compatible with this tensioner). For closure, you have two options: the metal seal for PP strapping, which requires a manual sealer to close (professional system, permanent and flat closure), or the plastic buckle, which closes without an additional tool (useful for low volume or occasional re-strapping). Choose one option or the other depending on the frequency of use.
Maintenance and Care
A well-maintained tensioner lasts for years in professional operation. These are the basic routines that keep the mechanism in working condition:
- After each workday, remove dust and strap residue from the serrated wheel mechanism with a dry brush; accumulated dust in the grip is the most common cause of grip loss.
- Every two weeks (intensive use) or monthly (regular use), apply a drop of multi-purpose oil to the lever's pivot point; this maintains fluidity and prevents premature wear.
- Store the tool in a dry place. Although the main body can withstand occasional moisture, rust on the serrated wheel degrades the grip over time.
- Visually inspect the wheel teeth at least once a month: if you notice irregular wear or deformed teeth, the tool is at the end of its useful life.
Do not use this tensioner with PET (polyester) strapping. PET requires much higher tensioning force and a mechanism sized for that load; applying PET in a tensioner calibrated for PP deforms the mechanism and ruins the tool in a few operations. For PET strapping, use the specific manual polyester tensioner.
Frequently asked questions
Does this tensioner work with any strap width?
No. It is calibrated for PP (polypropylene) strapping from 13 to 16 mm wide. Below 13 mm the strap slips out of the mechanism; above 16 mm it does not fit into the slot. For wider straps or for PET strapping, you need a different tensioner.
Can I use the tensioner without pliers if I work with a plastic buckle?
Yes. The plastic buckle allows you to close the strap without pliers or a metal seal: tension with the tool, fold the tip over the buckle and release. It is a valid option for low volume or occasional strapping. For daily professional strapping, the seal + pliers system offers a more secure and faster closure.
How many turns of strapping should I wrap around the package?
It depends on the weight and geometry of the load. For light cardboard boxes with a stable base, one horizontal and one vertical turn are usually sufficient. For pallets with stacked boxes, two intermediate horizontal turns and one top turn are common. If the load is high or unstable, increase the number of turns and check the result by pressing the strap with your finger: it should be firm and barely yield.
