Spiral Coil Binding

When it comes to producing flexible documents, not all binding methods are up to the task. Plastic coil binding, also known as spiral coil binding, is the preferred method of professionals and hobbyists that frequently produce food menus, pocket guides, training manuals, and much more. Binding any kind of document with plastic binding coils requires the right supplies. Binding101 offers a wide selection of spiral binding supplies that can help you improve production time from start to finish and the overall quality of the documents you prepare. We offer a broad variety of plastic coils, pre-punched paper, and pre-punched report covers to help you stock up on all the supplies you need at affordable prices.

With spiral binding plastic coils, you can make professional books that can withstand heavy handling. This is because the plastic itself is incredibly flexible and durable, with the ability to be bent any which way and still retain its original shape.

Binding with coil is simple and only requires a few tools. You will need a coil binding punch, the coils themselves, and cutter crimper pliers. An optional addition would be an electric coil inserter to increase the rolling/inserting speed. All you have to do is punch your pages, roll your coils through the holes, and then cut/crimp in each end of the coil.

Spiral coil binding machines are one of the most popular solutions, punching closely spaced holes to work with plastic spiral coil spines. Some machines may also have integrated coil inserters to roll the coils into the holes, and crimping machines to crimp-in the edges of the coil.

Spiral binding coils are flexible and available in a huge selection of both stocked and special-order colors. Standard 12" lengths are most common, but extra-long 36" coils are also available. There are also various pitches, including standard 4:1, specialty 5:1, and more.

Coil Binding Pitch

If you're new to document binding, or maybe just switching gears to try a different binding method than normal, and you run into the word "pitch" to find yourself a bit confused over the meaning...you're not alone! One of our most frequently asked questions is simply, "what is a binding pitch". So let's get straight to the answer, shall we?

A binding pitch refers to the spacing between the holes, which translates to the spacing between the prongs of your binding spine. The pitch is written in a ratio format with a number, a colon, and a second number. For example, 4:1 which reads "four to one".

The first number is the number of holes while the second number is the measurement, which in the USA is "inch". So 4:1 indicates that the binding and hole pattern has 4 holes for every 1 inch of length.

So when we start to talk about hole spacing between each individual hole, rather than in a pitch format of 'holes per inch', it is important to know that the measurements are center-to-center. This means it is not just the paper space between your holes, but the space from the same point on 1 hole to the same space on the next hole (or left-edge to left-edge, or right-edge to right-edge...you get the idea?). Here is a photo to help clarify...

Spiral Coil FAQs

1. What coil bind pitch do I need? The most common binding pitch for spiral coils (by far) is 4:1 pitch, but some industry-specific customers use a 5:1.

2. What is the largest book a coil can bind? If you're talking about sheet size, then the limit of size will depend on your machine. That being said, spiral coil binders are stocked in a 36" length (in addition to the standard 12" length) so you can bind a book up to 35" long. If you're talking about book thickness, then the answer is about 440 sheets (20 lb bond copy paper), or a 1 ¾" thick stack using the largest coil available, a 50mm.

3. Why is the coil longer than my book? Spiral coils are 1" longer than the intended binding edge length to allow for cutting and crimping-in each end. This leaves 1/2" on each side of your page; smaller extensions can be more difficult to handle. So, for example, standard coils are 12" long and intended for letter size paper that is 11" long.

4. How do I know what coil size I should get? The most accurate way to determine the best coil size for your book is to lay all of your pages on a desk (including covers and any inserts) and measure the thickness of the stack, then add 1/8" to that. Make sure you are not pressing your pages down when you measure them; just allow them to lay loose. If you press down, you may end up with a coil size that is too small to allow your pages to freely turn. Sample: My book is 5/16" thick + 1/8" = 7/16" should be the coil size. Since coils are measured in millimeters, not inches, you can use a conversion calculator like this to convert it. My 7/16" coil becomes 11.11 mm. Always round up to make page-turning easier, which would mean I should use a 12 mm coil for my book.

5. Is the coil size the outside or inside diameter? Coil binder measurements are the inside diameter, or "ID".

6. Can I buy smaller packs? Our coils are pre-packaged in packs of 100 or 50, depending on the size. We cannot break down packs to offer smaller quantities.

7. Can I buy assorted packs? At this time we do not offer assorted color or assorted size packs. But if there is a demand for them, we may do this in the future, so let us know that you want us to carry assorted packs by emailing info@buy101.com.

8. Is it possible to coil bind without a machine? Having a spiral coil binding machine will give you the most variety of binding, as you will be able to punch any kind of paper stock you want, but yes, coil binding without a machine is possible (and easy)! Simply get pre-punched front coverspre-punched backs, and pre-punched filler paper, along with the cutter/crimper pliers. Print your pages and, once all assembled, just manually roll the coil in through all the holes. Then crimp in the ends of the coil with the pliers. Note that some printers may not be able to run pre-punched pages, so check your user manual for compatibility.

9. How much do Spiral Binding Machines cost? The price of a coil binding machine will depend on the volume it can handle as well as the integrated features. They start at about $175 and go up to several thousands of dollars. Our experts can help you find the best coil binding machine for your budget; just call us at (866) 537-2244 .
