Practical insights on sealing zipper selection, technology, and quality control.
- ODM Sealing Zipper Development: What Good Joint Development Actually Looks Like
When a standard waterproof zipper is not enough, ODM development fills the gap — if the supplier engages early. A field guide to running a joint development project that ships.
- How to Specify Sealing Zippers for Inflatable Products
A practical checklist for sourcing airtight zippers for inflatables: pressure targets, hold time, flex zones, valve interaction, and the tests to demand before tooling.
- Why Zipper Bonding Technology Decides Whether a Seal Survives the Field
Most sealing zippers do not fail through the film — they fail at the bond. How hot melt cast TPU construction suppresses delamination where laminated films peel.
- IPX Ratings for Zippers, Explained: From IPX5 to IPX8
What IPX5, IPX6, IPX7 and IPX8 actually mean for zipper performance — and why the rating on the datasheet is only half the story.
- Waterproof Zipper vs. Airtight Zipper: Which One Does Your Product Need?
Water blocking and pressure retention are two different engineering problems. This guide breaks down when you need a watertight zipper, when you need an airtight one, and how to specify each.
