Custom Zipper — Polypropylene (PP) with Gunmetal Plating
We supply zipper to garment factories and brands, built in Polypropylene (PP) with gunmetal plating for outerwear and jacket programmes. On a trim like this the specification that decides the outcome is tape shrinkage matched to the garment fabric, so that is agreed in writing before bulk — not discovered when the first carton is opened on the line. Programmes start at 500 pieces per style per finish.
The failures here are predictable: a finish that tarnishes or rubs off after washing, or inconsistent sizing between production runs. We lock material, finish, dimension and tolerance before bulk, and prepare REACH and GPSR documentation so the shipment clears instead of sitting at port while your selling season passes.

Where it is used
- Denim and workwear — hard-wearing finishes that survive industrial washing
- Outerwear and tailoring — matched to the shell fabric so it drapes with the garment
- Childrenswear and schoolwear — tested to the destination's safety standard
- Bridal and eveningwear — small runs with hand-finished detail
- Uniform and corporate programmes — repeatable spec held on file for reorders

Packing, testing and delivery
Trims are packed to the ratio you specify — by size, by colour or by garment set — with barcodes applied where the line needs them. Test reports for OEKO-TEX Standard 100 for dyes and trims are prepared for the destination market. We ship to Rotterdam or Felixstowe with the commercial invoice, packing list and certificate of origin, and hold the approved reference so reorders reproduce the same material, the same finish and the same tape shrinkage matched to the garment fabric.
