Comb bindings are more vulnerable to damage than spiral bindings. Adjoining pages are held more tightly in register with each other than with spiral bindings. Comb bindings come in several colors and allow screen printing on a document’s spine. They can bind pieces up to 3" thick. With comb binding, pages can easily be added or removed.
Plastic comb bindings allow pages to lie flat when opened. However, they cannot be doubled back. And inserting them is a hand operation that is quite costly for large numbers of documents.
