Nylon Coil Zippers 

The most common type of zippers. 

They used to be made from nylon and are still commonly referred to as nylon coil zippers even though now they are typically made from polyester.

Coil zippers are lightweight, heat resistant, and rustproof.

Invisible Zippers 

Most often used in dresses and skirts. 

The coil on an invisible zipper is located on the back side of the zipper and will not be visible from the front of a garment after the zipper has been installed. 

Invisible zippers are usually coil zippers with a tear drop pull.

Metal Zippers 

It have two lines of metal teeth that have been molded and placed on either side of the tape at regular intervals. The teeth can be made from aluminum, nickel, or brass. They are most commonly found on jeans.

Plastic Molded Zippers 

The same as metal zippers except the teeth have been molded out of plastic.
