Company Profile.pdf

Colors PET Plastic Spiral Coil Binding

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.
