When to Choose Spiral Binding for Your Book
Most softcover and hardcover books are bound using an adhesive glue. Spiral bound books, on the other hand, have series of small holes punched into the left-hand side of their pages. A coil is fed through these holes to form the binding. Most spiral coils are made from plastic, but some are bound with a metal coil called Wire-O. Wire-O offers the same level of flexibility with an added touch of sophistication.
