You could use this type of zipper on any pouch, but it probably works best on pouches with some depth. It might look odd on a flat pouch.
Mind the Gap
Before you use this kind of zipper, keep in mind there is going to be a small gap below the zipper on both sides of the finished pouch:
All the purses I've seen with this kind of zipper have this gap, so I'm not sure if it can be closed off. It isn't a big deal as long as you aren't using your pouch for really tiny things, but I wanted to point out that it is there.
If you are making a pouch that is a specific size, you might need to trim your zipper to a determined length. I'm just improvising here and making this pouch to fit this zipper.
I trimmed about half of both ends of the zipper tape away:
Make End Covers
Cut two pieces of fabric about 3" high x 2" wide (8cm x 5cm).
Fold ends up about 0.25" (7mm) at top & bottom:
Slide one end of the zipper into one end of a cover:
Fold it down to cover end of zipper and pin in place.
If your zipper still has the stops attached, mark your fabric so you can avoid them when sewing. Then sew the cover on:
Prepare Pouch Pieces
Since I'm improvising on my pouch size, I've cut the pieces the width of the length of the uncovered portion of my zipper + about 3/8" allowance on each side. Then just fold and press the top sides in the width of your allowance:
Here is the back:
Sew the pouch pieces to the zipper.
When you sew the sides of the pouch, start sewing from the bottom and sew up into the fold creases. Stop sewing about 1.25" - 1.5" (3 - 4cm) below the zipper:
Turn the pouch right side out. Pull the tabs to the right side through the gap on each side.
Slip stitch the lining & exterior layers together at the gap.
