How to specify a zipper for your custom bag

A useful zipper brief brings together the opening, chain, slider, puller and lining. Discuss the combination before sampling, then confirm the construction against the approved sample.

Zipper and case detail; specifications depend on the approved sample.

1. Define the opening

Mark the opening on a sketch or photo. Specify its position, whether it follows a corner, how many sliders you need and the items that must pass through it. Agree on finished opening and zipper measurement points; they may differ.

2. Match the components

Discuss chain type and size, tape colour, visible or concealed appearance, slider direction and puller shape as one set. A size number alone does not prove that parts from different chains or suppliers fit together. Confirm compatibility and any separate decorative puller on the sample.

A general example of positioning a slider on zipper tape. Confirm the component combination and operation on the approved sample.

Transcript

The zipper slider is positioned on the zipper tape. Check slider compatibility and smooth operation against the approved sample.

3. Check space and construction

Show where lining, padding, pockets and binding meet the opening. Review clearance around the slider and how zipper ends are secured, especially at corners or thick joins. Check whether the lining catches and whether the opening moves smoothly.

4. Review the sample

Check colour, finish, measurement points, slider direction and puller attachment against your brief. Test operation with the intended contents; agree separately on any test method, acceptance criteria and quantities. A zipper alone does not establish that the finished bag is waterproof.

Questions buyers often ask

Can I request a custom zipper pull?

Share your artwork, preferred size, material and finish. Compatibility and sampling options depend on the selected zipper.

How should I specify a laptop-bag opening?

Provide the device’s actual length, width and thickness, required opening and padding or pocket layout. Check fit on the approved sample.

Can zipper components match my brand colour?

Provide a colour code or physical reference and specify whether it applies to tape, teeth, slider or puller. Confirm availability and colour on a sample.

What should I include in an OEM inquiry?

Share a sketch or sample, opening position and length, component preferences, quantity, destination and packaging requirements. Mark unresolved details for discussion.
