Quick Answer

For most bag making projects, nylon coil zippers offer the best balance of flexibility, light weight, and quiet operation. Standard zippers (often metal or molded plastic) are better when you need extra durability or a specific aesthetic.

Flexibility and Weight

Nylon coil zippers are made from continuous polyester or nylon coils, making them highly flexible and lightweight. This allows them to bend easily around curves and corners, which is essential for bag styles like backpacks, duffels, or rounded pouches. Standard zippers, such as metal or molded plastic, are stiffer and heavier, limiting their use on curved seams.

Durability and Strength

Standard zippers, especially metal ones, are generally more durable and resistant to wear from heavy loads or rough use. However, for most bag making, nylon coil zippers are strong enough for daily carry items like totes, crossbody bags, and small accessories. They are also less likely to damage fabric or sewing needles.

Appearance and Application

Nylon coil zippers have a smooth, low-profile look that blends well with fabric, making them ideal for hidden or exposed zippers in bags. Standard zippers often have a more prominent tooth structure, which can be a design feature but may also catch on linings or contents. For projects requiring a double-slide zipper (opening from the center), nylon coil zippers are easier to create because you can cut them to exact length and add two sliders.

Nylon Coil vs Standard Zippers: Tradeoffs

  • Nylon Coil Zippers: Flexible and lightweight. Quiet operation. Can be cut to length for custom projects. Best for curved seams and double-slide zippers. Less durable under extreme weight.
  • Standard Zippers (Metal or Molded Plastic): More durable and rigid. Heavier and noisier. Limited flexibility, not ideal for curves. Often come in fixed lengths. Better for heavy-duty bags or when a decorative metal tooth is desired.
  • Choosing for Your Project: Consider the bag style: backpacks and curved pouches favor nylon coil; structured totes or heavy-duty bags may benefit from standard zippers. Also think about aesthetics and noise level. For most bag makers, nylon coil zippers are the versatile default choice.
