Zipper Tape for a Fast Fashion Retail Chain in Czechia
A Fast Fashion Retail Chain approached us with a zipper tape requirement for the Czechia market. The brief was specific: a defined look, a hard launch date and a unit cost that had to survive freight and duty. This case study records what was specified, what went wrong in sampling and how the bulk order was delivered.
The challenge
- Elastic that lost recovery after three washes
- Lead time quoted without the plating or dyeing sub-process
- Shrinkage that only showed up after the first wash
What we specified
| Item | Zipper Tape |
|---|---|
| Client type | A Fast Fashion Retail Chain |
| Market | Czechia |
| Order volume | 10,000 pieces across 4 specifications |
| Base material | Nickel Silver |
| Standard size | 6 mm Width |
| Finish | Sandblasted Finish |
| Sampling rounds | 3 |
| Delivery window | 8 weeks from PO to ex-factory |
| Compliance | RoHS |
How it was resolved
- We rebuilt the specification around Nickel Silver and locked the tolerance before bulk.
- The finish was moved to Silicone Wash Finish after strike-off tests showed better durability.
- A pre-production sample was approved and retained as the golden reference.
- Production ran with in-line inspection and a mid-run photo report.
- Cartons were packed to the client's own barcode and ratio specification.
Result
- 10,000 pieces delivered inside the 8-week window.
- Unit cost held within 3.0% of the original quotation.
- Inspection-related rejection stayed under 1.5%.
- The specification is now on file, so reorders reproduce the approved sample.
What we would repeat
Approve a pre-production sample made from the actual bulk base material. Substitute material behaves differently in finishing.
