Comb binding is one of the many ways to secure pages together into a book. This method utilizes round plastic spines, 19 rings, and a hole puncher that makes rectangular holes. Comb binding is sometimes referred to as plastic-comb binding or spiral-comb binding, too. Our printing firm has a large variety of different-sized comb bindings, ranging from 3/16 of an inch (for 10 sheets of 20# paper) up to 2 inches (for 400 sheets of 20 pound paper). We can also provide a variety of different colors to enhance the appearance of your project.
