Coil binding, also known as spiral binding, is a commonly used book binding style for creating documents, reports, presentations and proposals. This binding style is known by a number of names including spiral coil, color coil, colorcoil, ez-coil, plastic coil, spiral binding, plastikoil and coilbind. Documents bound with helical coil (usually called spiral coil) can open flat on a desk or table and offer 360 degree rotation for easy note taking. This binding style is durable and is often used for documents that need to be mailed. Spiral coil binding spines are also available in more colors and sizes than other binding styles.
