Metal Coil vs. PVC Coil for Binding

Tuesday, June 25th, 2013

Coil Binding SuppliesCoil binding is THE most popular binding method used today. It has quickly passed up coil and comb for many reasons. For many reasons, the most popular binding coil used today is PVC coil. I still get many people, however, that ask me about the older metal coil and which is better. I would like to cover coil binding in general and explain the differences between metal coil and PVC coil. You can find our coil binding machines here.

Coil binding is a method of binding where spiral-like coils (much like springs) are inserted through pre-punched holes in paper. The spring-like nature of the coils allow punched paper to glide along the binding spine, making page turns easy, fast and seamless. Coil also allows pages to turn a full 360 degrees and allows pages to lay entirely flat.

In the United States of America, the 4:1 pitch is almost always used with 5:1 pitch being rare. The pitch of the coil is the hole pattern used. A 4:1 pitch consists of four holes per inch of paper and a 5:1 pitch is five holes per inch. The hole pattern you use depends a lot on how much paper you are binding (larger spacing means higher capacity) and your own personal preference.

As mentioned earlier, there is both metal and PVC coil binding. Here are some of the differences between the two:

  • Metal Coil – As a general rule, the metal coil is used on an industrial level for binding things like spiral notebooks for ruled paper. Metal coil is usually a shiny metal, silver or chrome color, although colored metal coil is available. One reason many people and businesses are moving away from metal coil is because it tends to bend easily, making page turns more difficult.
  • PVC Coil – This type of coil is used by most businesses and for home binding purposes. It is also beginning to find its way into more industrial binding applications for spiral notebooks. PVC coil does not bend, making it far more long lasting and durable than metal coil. Black is the most common color, although white and clear are other popular colors. You can buy PVC coils in a variety of colors including blue, green, brown, yellow, orange and much more.

The binding machines we offer at ABC Office are designed to be used with PVC coils. We get asked frequently if metal coils can be used with PVC coil machines. If the hole patterns line up, there is no reason you can’t use a PVC coil machine to punch the holes for metal coil. Be aware, however, that the coil crimping pliers will NOT work with metal coil. The inserter should work fine as long as there are no burs on the metal coil. The inserter used on PVC coil binding machine is made out of rubber and may scratch or tear if put in contact with low quality metal wire.

We have a lot of years working with coil binding machines and a lot of experience. Combined, we have near 85 years worth of binding machine experience and knowledge we can share with you.
