3:1 Pitch Plastic Coil is a durable, flexible, and an affordable alternative to other binding methods. It will not chip, crack, corrode or distort over time, and will retain its shape even with repeated use. This 3:1 pitch plastic coil binding is also known as Spiralastic®, Spiral Binding, Color Coil or Spiral Coil.

This coil is perfect for binding large diameter plastic coil projects. 3:1 Pitch Coil is easier to use for large diameter books because there are fewer holes to insert the coil through. 3:1 pitch 6.5mm x 5.5mm oval punching dies are recommended, especially with larger coil (25mm & up).

Your plastic coil bound documents will be so flexible that they can open to a full 360° (front-to-back) and lie perfectly flat. The multiple hole format makes the binding extra strong and the plastic coil's "memory" resists bending. With its lightweight construction it's great for mailing.

Available in a variety of colors and sizes to finish almost any job, our plastic coil is CPSIA compliant (lead and phthalate free).
