Office Supplies Metal Wire Binding Coil

Spiral binding plastic coils are one of the most popular traditional binding methods available. They consist of a continuous spiraled coil that is made of durable and flexible plastic and is rolled into holes along a binding edge. Spiral binding coils offer a modern bookbinding alternative when compared to traditional plastic comb spines, while still being affordable and easy to use.

Another benefit of spiral binding coils over many other binding methods is that coil-bound books have the ability to flip pages completely around a full 360 degrees without damaging the contents, so they can lay flat and stay flat. This allows your book pages to flip all the way around from front to back for easy readability. The spines also bounce-back to their original shape, even after heavy use and bending.

How do I choose a spiral coil?

We are a factory, you can contact me at any time to customize the binding coil that suits you, we provide a variety of binding coil sizes, if you are not sure about your size, not sure about the spacing? Here are the steps on how to choose the binding coil you need to bu

1) Choose a Coil Size (Diameter)?

Now choose your coil size (diameter) for your document. You can use the coil bind capacity chart below to help choose the best size based on your stack thickness or your sheet capacity. Just note that the sheet capacity was calculated using sheets (not pages) that were all 20 lb. bond copy paper, without any covers; this means it can vary significantly depending on the stock you are using, which is why we recommend the stack thickness method instead. And remember: having a coil that is slightly too large is better than having a coil that is too small; a small coil won't allow pages to flip smoothly and can pinch them, tear more easily. So if you are between sizes, we recommend you size-up.

If you want an alternative solution to choose the best size, you can utilize this general rule of thumb:

1. Take the pages and covers being bound and lay the stack flat on a table.
2. Measure the thickness of the stack, but don’t press down; let it lay naturally loose.
3. Add 1/8" to the stack thickness - that will be the size of the binding coil recommended for your document thickness.
