Bag Zippers

Fast Facts

Purpose
Zippers create a secure opening that you can open and close repeatedly without tying, folding, or fastening separate parts.

Zipper types
Common choices include nylon coil, molded plastic or resin, and metal zippers. Each type gives the bag a different look, feel, weight, and level of flexibility.

Sizes
Manufacturers make zipper chains in sizes such as #3, #5, #8, and #10. Larger sizes generally use a larger, more noticeable chain.

Sliders
The slider moves along the zipper chain to open or close it. Designs include locking and non-locking sliders, as well as single and double-slider arrangements.

Pulls
The zipper pull gives you something to grip. Pulls can range from simple metal tabs to longer cord, rubber, or custom-shaped designs.

Colors
The zipper tape can match the bag fabric or create a contrast. Suppliers can also produce different chain, teeth, slider, and pull finishes depending on the zipper type.

Why choose it?
A zipper gives you quick access while keeping the bag opening fully closed when you need it. It works especially well when people open and close a bag often. Compared with a drawstring, a zipper creates a flatter, more controlled closure and does not leave an open gap around the top. You can also use the zipper as a visible design detail rather than hiding it.

Things to consider
Match the zipper to the fabric and the way people will use the bag. A large metal zipper can feel too heavy or stiff on a lightweight pouch, while a small zipper may look out of place on a heavier bag. Nylon coil zippers bend more easily around curves. Coated or water-resistant zippers can reduce water entering through the zipper area, but the zipper alone does not make the whole bag waterproof. The stitching, fabric, seams, and zipper construction all matter.

Customization options
You can choose the zipper type, chain size, length, tape color, slider style, pull design, and finish. Possible choices include nylon coil, molded plastic or resin, metal, reverse-coil, and coated zipper constructions. You can also use one or two sliders and choose locking or non-locking versions. Some suppliers make custom zipper pulls with a logo, shape, or special finish. Your fabric, bag construction, and order requirements will determine which options suit your design, so we need to confirm availability for each project.

Best suited for
Zippers suit bags that need frequent opening and a clearly defined closure, including storage pouches, cosmetic bags, packing bags, document pouches, and similar products. Flexible coil zippers work particularly well on softer fabrics and curved openings, while larger molded or metal zippers can suit heavier fabrics or designs where the zipper forms part of the visual style.
