Different types of zipper are described below:

Metallic zippers: These zippers are generally made of stainless steel, zinc, brass, nickel or aluminium alloy and are mostly found in jeans. The metal pieces are shaped into the form of teeth and are positioned in a zipper tape at uniform intervals. The metal zippers could be coloured in a variety of colours to match the colour of the garment.

Tooth Zippers: Teeth are equally visible on both sides of the zipper tape. Every tooth is separate. They are perfect for most straight applications like jackets, garment bags and totes.

Coil Zippers (nylon): Flat on one side with teeth on the other. Each tooth is connected to the next and bend easily. Use for backpacks, sleeping bags and tents. Shorter lengths can be used in purses and totes.

Invisible Zippers: Hidden in a seam with only the pull tab showing. They are flexible and strong. Use an invisible zipper foot to insert. Use in skirts, blouses, dresses—anywhere you need an invisible closure with a smooth finish.

Plastic-molded zippers: Plastic zippers mostly use polyacetal resin, though other thermoplastic polymers are used as well, such as polyethylene.

Open-ended zippers: Open-ended zippers use a box and pin mechanism to lock the two sides of the zipper into place, often in jackets. Open-ended zippers can be of any of the above-described types.

Closed-ended zippers: These are closed at both ends; they are often used in luggage.

Magnetic zippers: These allow for one-handed closure and are used in sportswear.
