Zipper Tape for a Startup Apparel Label in Brazil
A Startup Apparel Label approached us with a zipper tape requirement for the Brazil 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
- A zipper puller that broke under pull test at the warehouse
- Lead time quoted without the plating or dyeing sub-process
- An interlining that bubbled after the first press
What we specified
| Item | Zipper Tape |
|---|---|
| Client type | A Startup Apparel Label |
| Market | Brazil |
| Order volume | 5,000 pieces across 2 specifications |
| Base material | Iron |
| Standard size | 15 mm Width |
| Finish | Powder Coating |
| Sampling rounds | 3 |
| Delivery window | 10 weeks from PO to ex-factory |
| Compliance | ISO 9001 |
How it was resolved
- We rebuilt the specification around Iron and locked the tolerance before bulk.
- The finish was moved to Nickel-Free Electroplating 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
- 5,000 pieces delivered inside the 10-week window.
- Unit cost held within 4.5% of the original quotation.
- Inspection-related rejection stayed under 1.0%.
- 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.
