Our zipper tape with transparent exoskeleton shows the internal metal clips.

The transparent PVC plastic exoskeleton shields the internal metal clips to prevent corrosion.

Now, there are metal zippers that won’t corrode!

Note:

If the metal is already rusted before being coated with the polymer or elastomer then the zipper will look rusted.

This is why Zipr Shift will be sure to take care to ensure the metal does not rust before being coated.

Example:

Rusted metal will make a rusted zip. Non-rusted metal won’t rust in properly sealed zippers.
