    There are two main types of zippers: metal and plastic. Metal zippers are divided into those with wire teeth or die-cast teeth and come in various finishes like brass or silver. Plastic zippers are divided into five groups depending on how the coil or teeth are attached to the tape, such as being stitched or molded on. Specialty zippers also exist, including invisible zippers which are stitched to be hardly visible, two-way zippers for outerwear and luggage, and open-end zippers that can completely detach.

    Topic: Types of zippers

    There are two main types of zippers metal and plastic used in garments.

    Metal Zippers

    Metal zippers are divided into 2 groups, depending on the material used and the process of manufacture:

    Teeth formed from a metal wire, either flat or profiled and made from brass, aluminium, nickel or
    white brass (nickel-free)

    Teeth die-cast directly onto the tape, with zinc metal

    Metal zippers are usually made in a variety of finishes, such as golden brass, antique brass, antique
    silver, gunmetal, silver etc. These finishes are achieved by chemical treatment of the zipper chain and
    matching plating of the sliders and end stops.

    Plastic Zippers

    Plastic zippers are divided into 5 groups:

    LFC or L-type zippers made with meander/Ruhrmann type coil, stitched around the edge of the
    carrier tape.

    CFC zippers made with spiral coil, stitched on one side of the carrier tape.

    Woven-in coil zippers, in which the coil is formed and directly woven into the carrier tape on
    special looms.

    Plastic moulded zippers, in which the teeth/elements made from polyacetal (commonly known as
    Delrin ) are directly moulded onto the carrier tape.

    Plastic extruded zippers, in which a string of teeth/elements is first extruded and then stitched onto
    the carrier tape.

    Specialty Zippers

    The main categories of zippers, as described above, also include speciality zippers, which have special
    types of construction, or parts, or finishes. These include:

    Invisible zippers: CFC zippers have a special class known as Invisible zippers due to the special
    construction and mode of use. These zippers do not require provision of a fly, since they are made
    and stitched in such a manner that only a hairline seam is visible from outside. These zips are
    predominantly used in ladies dresses and skirts. These zippers are available in knitted and woven
    tapes.

    Two way zippers: These zippers are made usually in #5 or larger sizes in CFC, plastic moulded
    and metal. The major applications are outerwear and luggage. These are made in X-type or O-
    type.

    Open End zippers: Some zipper applications require a zipper to detached completely e.g. jackets
    and outerwear. Instead of a fixed bottom stop, box & pin attachment is used.
