Coil zipper—also known as nylon coil zipper—is a type of zipper whose teeth/elements are made from coiled monofilament that was traditionally nylon. The coil is sewn to a zipper tape to make the final product. The final zipper product is completed when the nylon coiled teeth are sewn onto the zipper tape. Nylon coil zippers have a continuous coil chain made from nylon. When this coil is positioned on the back of the zipper and not in the front, this kind of zipper is called invisible zipper.

Stronger horizontal strength is effortlessly achieved with the fabrication of coil zipper. These zippers also have easy repair; zipping and unzipping past the point of misaligned tooth easily repairs the nylon monofilament and the tooth efficiently fixes itself. Another advantage of nylon zippers is its two-way functionality. The sliders can be fixed in either direction of the zipper chain and they will still function smoothly. Coil zippers are the commonest type of zippers that are lightweight, heat resistant and rustproof. Therefore, they last long and work exceptionally well in whatever product they are used.

Nylon zippers are highly flexible and are available in a wide range of sizes. The high compatibility of the coil zippers is the main attribute for their huge number of applications in fashion wear, canvas goods, and bags. These types of zippers are also the top choice for the outdoor and luggage industries. Nylon coil zippers are most commonly found in tents, suitcases, backpacks, and other camping apparels.
Though nylon coil zippers are a very popular choice for a large number of applications, the use of nylon is now being replaced with polyester. Polyester coil zippers are also becoming widespread nowadays. But nylon coil zippers still remain one of the most manufactured zippers all across the globe. They are made in various gauge sizes and colors. This makes them well-suited to several items that are used daily. There are other variations of these coil zippers too which are also used extensively according to their requirements.
Benefits
Stronger horizontal strength is effortlessly achieved with the fabrication of coil zipper. These zippers are also great because of their ease of repair. Even a tooth that gets out of the alignment can be fixed flawlessly. Zipping and unzipping past the point of misaligned tooth easily repairs the nylon monofilament and the tooth efficiently fixes itself. Another advantage of nylon zippers is its two-way functionality. The sliders can be fixed in either direction of the zipper chain and they will still function smoothly.
Coil zippers are the commonest type of zippers that are lightweight, heat resistant and rustproof. Therefore, they last long and work exceptionally well in whatever product they are used.
Apart from high compatibility and strong construction, there are other numerous benefits of nylon coil zippers too. This is the reason why nylon zippers are preferably considered for various applications.
Manufacturing
The main elements required in the manufacturing process of coil zipper are a stringer, slider, and a tab. The stringer consists of a tape and teeth assembly and is an essential constituent of this zipper. The tab is used to pull the slider up and down which eventually opens and closes the zipper.
