To complete the PET strapping cycle, a plier with an aggressive bite and reinforced structure is required to seal the buckle without the polyester under high tension slipping or breaking the joint. This manual PET strapping plier —also called a crimper, sealer, or PET strapping tool— is manufactured by Maxtens from heat-treated steel with a lever mechanism sized for the specific force that polyester requires, designed for heavy-duty construction, export, and agro-industrial strapping.

Key Benefits

  • Reinforced jaws for PET: Bite area with deep teeth and heat-treated steel, calibrated to deform metal buckles on polyester strapping without the seal slipping under tension.
  • High force ratio lever: Long handles multiply the operator's manual force to close buckles on heavy strapping, without requiring excessive physical effort during long shifts.
  • Compatibility with commercial widths: Works with PET strapping buckles from 13 to 20 mm, the standard formats for heavy-duty and industrial logistics.
  • Non-slip grip: The handle coating maintains a firm grip with gloves during outdoor operation, on site or in an agricultural yard.
  • Careful Maxtens manufacturing: Reinforced joints with controlled tolerances, which maintains the fluidity of the closure during continuous use in heavy pallet strapping.

Typical Applications and Uses

  • Closing of palletized heavy construction materials: bricks, blocks, grouped cement bags.
  • Sealing of wood loads, metal profiles, and industrial parts for transit or export.
  • Agro-industrial operations with dense bags, bales, or palletized bulk product.
  • Closing of bulky packages with heavy strapping for prolonged storage or inter-island transit.

Quality and Durability

An economical PET plier fails in two areas: the jaws lose their teeth due to premature wear (which produces seals that slip under the actual tension of the polyester) and the joint yields with intensive use. Maxtens works with heat-treated steel and a lever mechanism with controlled tolerances, which maintains the sealing quality for years of heavy-duty strapping. In export operations where the pallet spends days in transit, a loose seal is equivalent to losing the load: the difference is measured in real shipping security.

Does this crimping tool work for PP strap or only for PET?

Mechanically it can crimp seals on PP strap, but it is not the optimal tool. The PET crimper has more aggressive teeth due to the higher tension of polyester, and applying that bite on the softer PP strap can break or shred the tape. For PP strapping there is the dedicated PP crimper, better calibrated for that force. For mixed PP+PET operations, many setups keep the two tools as separate units.

Does the crimper also tension or cut the strap?

No. Its function is exclusively to crimp the metal seal over the joint of the already-tensioned strap to close the cycle. Tensioning is done with a separate tensioner and the excess strap is cut with the built-in blade on the tensioner itself or with a dedicated cutting tool. For full closure in a single operation, the battery-powered combination strapper integrates tensioning, sealing and cutting in one step.

What maintenance does it need to keep sealing quality?

Low maintenance. Apply light lubricant (multi-purpose oil) to the joints every set number of intensive-use cycles to keep the closing motion smooth, and clean the jaws of dust, plastic debris or seal residue that may accumulate. In very high-volume operations, the jaw teeth can benefit from periodic inspection to make sure the seal still applies the correct pressure.

What sets apart a professional PET crimper from a low-cost one of the same format?

Three critical points. First, the jaw teeth: the teeth of a professional crimper are sized to bite at the depth PET requires, while those of a low-cost one are usually shallow and leave seals that slip. Second, the jaw material: heat-treated steel that withstands wear versus carbon steel that wears out within a few thousand cycles. Third, the smoothness of the joint, which under heavy use is the difference between a productive shift and constant stoppages.
