Woven and PET strapping: start joint selection with the whole system

“Polyester strap” can refer to products that look and behave differently in a packing process. YAKU’s catalogue separates black woven polyester strap from green embossed PET strap. That distinction should remain visible when discussing how the ends will be joined.

The useful question is not simply which closure fits the nominal width. It is which combination of strap, closure, tool and application has been defined and evaluated for the job.

Woven strap and wire buckles

YAKU lists woven strap in nominal widths from 13 to 32 mm on request. Wire buckle enquiries should identify the actual strap reference alongside the buckle width, wire diameter and finish. A width match narrows the catalogue discussion but does not complete a compatibility assessment.

Ask the strap supplier what buckle and tensioning arrangement is specified for that strap grade. If a different buckle is proposed, treat it as a change to be reviewed. Keep the original reference and the proposed alternative distinct during sample evaluation.

Our finish comparison guide explains why galvanized and phosphated options should be considered within a matched system. Do not use coating colour as the only basis for a decision.

PET strap and the joining method

For a clipped PET joint, the strap grade, thickness, surface, clip profile and crimping tool all belong in the enquiry. YAKU’s sheet metal clip range includes nominal widths of 12, 16 and 19 mm with catalogue sheet thickness of 0.50 mm. That identifies the listed component; suitability still depends on the proposed combination.

PET strap can also be joined by suitable friction-welding tools. Signode’s BXT product documentation describes tools that friction-weld plastic strap without an additional seal or buckle and identifies their applicable strap ranges. This is an example of a different joining process, not evidence that any PET strap works in any welding tool.

If the packing line already uses a welding tool, record that fact before requesting metal closures. If the line uses a crimped closure, identify the tool and profile rather than assuming a generic metal clip is equivalent.

Steel strap is a separate catalogue discussion

YAKU’s steel strapping seals are a separate family from the sheet clips listed for PET and PP. Their seal profile and sheet thickness need to be established for the steel strap and sealer being used.

Signode’s explanation of seals distinguishes different joining mechanisms. This is why procurement should preserve the actual closure description. “Metal seal” is too broad to define a replacement across different strap systems.

Agree what the evaluation is meant to prove

A practical review begins with an agreed application and an identifiable combination. Record the strap reference, closure part number, tool, relevant settings and the acceptance requirement. Keep the evaluated sample separate from unapproved alternatives.

Decide which evidence is needed for your decision. A dimensional check can establish whether a supplied component matches the agreed dimensions. It cannot establish a joint strength value. A joint test also needs a defined method and a clear record of the components being tested.

Avoid converting a tool’s tension setting, a strap’s breaking value or a buckle’s wire diameter into an assumed cargo capacity. These describe different things. Our wire diameter guide develops that distinction with a simple geometric example.

Unitising and cargo securing are different tasks

A strap arrangement that holds articles together as a bundle does not automatically secure that bundle inside a container or vehicle. The IMO/ILO/UNECE CTU Code treats bundling and strapping as auxiliary measures alongside the securing measures needed for cargo in a transport unit.

For procurement, keep these requirements distinct: the packaging joint your team is selecting and the transport securing arrangement planned for the load. The responsible packing and transport specialists need enough information to assess each.

Use the systems page to explore the catalogue, then send an enquiry with the strap reference, tool and intended application. Performance values, roll lengths, supply availability and lead times are established on request for the actual proposed supply.
