PU Leather Shank Button for Jackets — Specification, Uses and Sourcing Notes
PU Leather Shank Button for Jackets: Specification, Uses and Sourcing Notes
PU Leather Shank Button is the version buyers specify for jackets when the base material is fixed by performance rather than by price. This entry sets out what the material actually changes, which specification to write into the tech pack, and where the cost sits — the three questions that decide whether the item passes bulk approval.
What it is
PU Leather gives shank button its strength and surface character. In practice that means the trim behaves differently in cutting, in finishing and in wear: plating and coating adhesion must be tested on the actual base. Buyers who specify the material up front avoid the most common failure — an item that looks right on the sample card and behaves differently in bulk.

Properties that matter in buying

- Mechanical performance — elastic recovery after 30 cycles or washes.
- Compliance — REACH SVHC Screening documentation issued with the shipment.
- Consistency — the approved counter sample becomes the reference for every reorder.

How to specify it
- Name the base material in the tech pack, not just the item.

- Order the test report against the standard your market requires.
- Retain a golden sample at the factory and a second one with you.
