Spiral Binding Plastic Coils (Price per Box)

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 a durable and flexible plastic. To bind, these coil spines are spun through several closely spaced holes, and then crimped in on the edges. They allow your book pages to flip all the way around from front to back, and are extremely flexible and durable, so will bounce-back to their original shape, even after heavy use and bending. This makes them the best binding solution for schools, travelling sales people, product manuals, and so much more. If you're ready for one of the most durable binding spines available, then buy standard spiral binding plastic coils online at Binding101 today.

Spiral binding coils offer a more modern and durable way to bind books over the traditional comb spines, while still being affordable and simple to use. A benefit of spiral binding coils over many other binding methods it that, coil bound books have the ability to flip pages completely around a full 360° without damaging the contents, so they can lay flat and stay flat. The variety of colors available is vast, with colors including black, white, clear, red, blue, maroon, green, and more! Special-order colors, like yellow and pink, are also available by request - call (866)537-2244 for a quote on custom colored coils. Sizes range from 6mm (1/4") up to 50mm (2") allowing for books as thick as about 440 sheets of 20 lb. bond to be bound.

What Kind of Coils Do I Need to Buy?

We offer a huge selection of spiral binding coils for you to choose from, most stocked in all of our nation-wide USA warehouses for fast shipment and delivery. There are 4 different categories of coil to choose from, including length of the coil, the pitch, the diameter or coil size, and the color. Here is how to choose the binding coils you need to buy...

Choose a Coil Length

First, choose your coil length. 12" coils are made for letter size pages, and are the most popular choice. 36" length are a bit more specialty, primarily used by print shops are those wanting to make multiple books from 1 coil.

Choose a Coil Pitch

Once you have chosen the length of your coil bind spine, choose your pitch. What is a binding pitch? Pitch refers to the holes per inch, or the hole spacing. They are reflected in a ratio that includes the number of holes:inch...for example, 4:1 means there are 4 holes per inch and 5:1 means there are 5 holes per inch. 4:1 pitch binding coils are by far the most popular, as it is the standard spacing for coils in the US. About 98% of our customers order 4:1 pitch spiral bindings. The 5:1 is a specialty spacing that is manufactured primarily for print shops who have specialty equipment for punching the pattern.

Choose a Coil Size / Diameter

Now choose your coil diameter for your page capacity. You can use the capacity chart here to help choose the best size based on your stack thickness or an estimate of your sheet capacity. Finding how to choose the best coil size is easier than you may think with our capacity chart. There is also a general rule with 3 simple steps to get the proper fit for any kind of binding that works as well: ① Take the book being bound and lay it flat on a table. ② Don't compress the paper and measure the thickness of the binding edge. ③ Take the measurement and add 1/8" - that will be the size of the binding element recommended for your document thickness.

Choose a Coil Color

Lastly, choose your coil binding comb color. Stocked colors for 12" long 4:1 pitch coils include black, white, clear, royal blue, navy blue, red, maroon, and forest green. The colors are solid, not coated, so even with heavy use and scratching, they will remain. Black coils are the most popular choice, while white and clear are close behind. Maroon, navy blue, and forest green are popular choices for professional institutions, as they often match corporate branding. Red and royal blue are brighter and more vibrant than the others, so are more common for schools and other organizations where a brighter colored coil is needed. 36" length and 5:1 pitch coils are stocked in white and black for most sizes, and some select sizes might also be available in other colors, but not all colors come in these more specialty sizes.

* You will also see that we offer a "sheet capacity" rating above. Using this method of size selection may be less accurate, as it was calculated using all 20 lb. bond paper, with no covers and no other paper stocks. The actual sheet capacity will vary depending on what paper stock and covers you are using. For this reason, we recommend you use the stack capacity for a more accurate fit. All of these capacities are approximations.
