Spiral binding coils (also called plastic coils) are a modern and durable way to bind books. Spiral binders are made of continuous plastic coil, similar to the look of a phone cord, that is spun through a series of closely spaced holes. The edges are then crimped in to prevent the coils from rolling out. Books that are bound with spiral binding coils can turn a full 360° so so they can lay flat and stay flat. Binding coils are durable and retain their original shape, even with excessive use, making them great for schools and other industries where books will be frequently handled. You can choose from a large variety of coil colors and sizes to fit your exact needs. Custom cut sizes and special colors are also available by request. Please contact us for more information.
