Coil
binding,
also known as spiral binding, is a commonly used book
binding style for documents. 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.
