Two-Way Separating Zipper Sourcing Program for Car Seat Cover Makers: Backpacks
Two-Way Separating Zipper Programme for Car Seat Cover Makers: Backpacks
This programme covers the full path from a two-way separating zipper requirement to a repeatable bulk supply for car seat cover makers. Instead of buying whatever a catalogue happens to stock, you specify the base material, the 15 mm Width, the finish and the packing, and we hold that specification so every reorder matches the last one. It is built around backpacks, which is where most of the specification detail sits.
The most common failure in two-way separating zipper sourcing is not price — it is drift. A base material changes mill, the shade moves, a plating bath changes and the item quietly stops matching the approved sample. We prevent that with a written spec, an approved counter sample and a golden sample retained at the factory.

What the programme covers
- Specification build from your tech pack or a physical reference sample
- Base material and finish options with costed alternatives
- Sampling, testing and approval against California Prop 65
- Bulk production with in-line inspection and photo reporting
- Packing, documentation and shipment under the agreed Incoterm
Recommended specifications
- Aluminium — chosen when the item has to survive repeated laundering
- ABS Resin — chosen when the item has to survive repeated laundering
- TPU — best balance of cost, availability and test performance
- Copper — chosen when the item has to survive repeated laundering

FAQ
What is the minimum order quantity?
Standard MOQ is 3000 per style per colour. Mixed colourways can be combined on the same spec if the base material is identical.
Can you handle our own artwork or tooling?
Yes. Artwork files or existing tooling can be used; we confirm tolerances in writing before the first production run.
What happens if a bulk lot fails inspection?
The lot is reworked or remade at our cost. Inspection reports are shared before the balance payment is due.
How long does sampling take?
14 working days for the first sample, with 3 days per revision round. Plated or dyed-to-match items add a few days.
Tell us the item, the quantity and the delivery window. We will quote it with the sub-processes named, so the lead time you approve is the lead time you get.
