THE ULTIMATE ZIPPER TECHNICAL GUIDE
Master the anatomy, materials, and sizing of industrial-grade zippers. A complete reference for designers and manufacturers.
The Anatomy of a Zipper
Tape
The fabric part of the zipper that is sewn onto the garment. Usually made of polyester, cotton, or blended synthetic fibers.
Teeth / Chain
The continuous pieces formed on both edges of the tape that interlock with each other when the slider is pulled.
Slider
The central moving hardware that joins or separates the teeth when pulled up or down.
Puller
The attached part of the slider that you hold. Highly customizable for brand identity and logos.
Top & Bottom Stop
Metal or plastic components fixed at the ends of the teeth to prevent the slider from sliding off the chain.
Material Selection Guide
Metal Zippers
Features individual metal teeth (brass, aluminum, or nickel) clamped onto the tape. Highly durable with a premium, heavy-duty aesthetic.
Nylon / Coil Zippers
Made from continuous coiled monofilament nylon. Extremely flexible, lightweight, and capable of self-healing if a tooth is misaligned.
Resin / Plastic Zippers
Injected molded polyacetal resin teeth melted directly onto the tape. Excellent corrosion resistance and performs well in extreme weather.
