What is the Difference Between Zippers?

In the zipper life, there are a few choices. With a good deal of options, there are some that are paralyzed by the number of possibilities when ordering zippers. One of our customer service representatives worked with a client for 2 hours trying to help her make a decision. This post will give you some insight between the teeth and what each tooth style is regularly used to.

What is the Difference Between Zippers?

For the most part, a zipper will always be used as a device to close or fasten a bag or apparel piece. The biggest difference between zippers are the teeth and the application.

At our zipper factory, we categorize the teeth in the following buckets: Nylon Coil, Plastic Molded, and Metal zippers. Once these zippers are in their respective buckets, it’s just the gauge size that sets them apart.

1a. Nylon Coil – The Nylon Coil Zipper is made exactly how it’s named. There’s a nylon monofilament that is “coiled” to form the teeth. It’s then sewn onto the zipper tape to make the final zipper product. Nylon Coil zippers are the zippers of choice for the outdoor and luggage industry. Tents, backpacks, suitcases, and camping apparel, you’ll most likely find nylon coil zippers. With the construction of the nylon coil zipper, it lends itself to have a stronger horizontal strength.

We’ve all stuffed our luggage a bit too much and that zipper holding the suitcase from exploding is a nylon coil zipper. Nylon coil zippers are also pretty easy to repair, should a tooth get out of alignment. The nylon monofilament can easily correct itself by zipping and unzipping past the point where the tooth is misaligned and most times it will fix itself. Another thing to note is that with nylon coil zippers, the sliders can be put on the zipper chain either direction and the zipper will still function.

1b. Invisible Zippers – There are two types of hidden zippers. An exact Invisible Zipper that is most often used in women’s skirts and a reverse coil or an Invisible Identical Zipper, as we call it. The Invisible Zipper is sewn into the seam of a skirt to create a clean finish. If you look at an Invisible Zipper closely, you’ll see that there are pleats on the zipper tape that allows the sewer to sew all the way to the seam line. 

The Invisible Identical Zipper (IIZ) on the other hand is a regular Nylon Coil zipper that is oriented backward to give an invisible look. With this type of zipper, you cannot sew all the way to the seam because there needs to be room for the slider to move. Invisible Identical Zippers are most commonly used when your design is calling for a clean finish, and you need a bit of a more substantial gauge than an Invisible Zipper. I’ve seen them applied on pieces of luggage to center front zippers on apparel.

2. Plastic Molded – Plastic Molded zippers are made from an acetal polymer that is extruded through a mold to shape the teeth. The teeth are perfectly symmetrical which means that the slider for plastic molded zippers can run in either direction. Plastic molded zippers are pretty versatile. They are mostly used on apparel and some handbags. It just depends on the look of the final design. Some like the “chunky’ look of the zipper teeth and take that into consideration of the design. The horizontal strength is decent, however, if one of the zipper teeth break over time, it’s almost impossible to repair one tooth.
