Spiral binding is a method of binding pages together using a continuous spiral coil, typically made of plastic or metal. This technique allows pages to lay flat when opened, making it ideal for notebooks, reports, and presentations. The spiral is threaded through holes punched along the edge of the pages, providing durability and flexibility. This binding style is popular in various settings, including schools and offices, due to its ease of use and ability to accommodate a large number of pages. It is often used for workbooks, calendars, and manuals, offering a practical solution for organizing documents.
