Closing the PP strap strapping cycle requires a pair of pliers that seals the metal clip with uniform pressure and withstands intensive use without the jaws deforming. This manual PP strapping plier —also called a sealer, crimper, or strapping tool— is manufactured by Fortemo from heat-treated steel with long, lever-multiplied handles, designed for warehouses, distribution centers, and palletizing operations where serial strapping is part of the daily flow.
Main benefits
- Heat-treated steel jaws: the biting area resists intensive use without deforming, which maintains the quality of the seal for thousands of closures.
- Long handles with multiplied leverage: the length of the arm allows the necessary pressure to be applied with little physical force, reducing fatigue during long strapping shifts.
- Calibration for PP metal clips: the bite is sized to deform the clip over polypropylene plastic strap without breaking it or leaving it loose, which is the typical problem with PET pliers used with PP.
- Non-slip grip: the handle's coating maintains a firm grip with gloves and prevents slipping with sweaty hands or operation in dusty areas.
- Careful Fortemo manufacturing: reinforced joints and a closing mechanism with controlled tolerances, which is noticeable in the smoothness of continuous work.
Typical applications and uses
- Closing palletized corrugated cardboard boxes in logistics warehouses and distribution centers.
- Sealing packages and light groupings in hardware stores, businesses, and parcel operations.
- Closing bundles of plastic pipe, light profiles, or material grouped in a workshop.
- Sealing compacted cardboard bags, regional export boxes, and packaged products.
Quality and durability
An inexpensive pair of pliers fails in two ways: the jaws deform with intensive use and the central joint loses fluidity with dust or debris. Fortemo works with heat-treated steel and factory-lubricated joints, which separates a pair of pliers that will last for years of professional operation from one that will fail after a few thousand closures.
Mechanically it can crimp seals on PET strap, but it is not the optimal tool. The PET crimper needs a more aggressive bite due to the higher tension polyester carries, and a tool sized for PP can leave the seal loose on heavy loads. For intensive PET strapping, the right choice is the dedicated PET crimper, with jaws calibrated for that force. For mixed PP+PET operations, many setups keep both.
Seal only. Its function is to deform the metal seal over the joint of the tensioned strap to close the cycle. Cutting the excess strap is done with the tensioner (which usually includes a built-in blade) or with a separate cutting tool. Some battery-powered strappers integrate tensioning, sealing and cutting in a single step, but in manual strapping each function is covered by a separate tool.
The body is in heat-treated steel and resists humidity and occasional outdoor use without trouble. For continuous outdoor use with rain exposure, Caribbean salt-air environments or storage without a roof, it should be dried and stored under cover at the end of the shift to extend the coating's service life. The central joint accepts periodic light lubrication that keeps the mechanism smooth in any condition.
The difference is in two points: jaw material and joint quality. A budget crimper uses untreated carbon steel that deforms with intensive use, and joints with play that lose proper pressure within a few thousand cycles. This unit uses heat-treated steel and reinforced joints, which translates into uniform seals over years of operation vs. months on a low-cost tool.
