Spiral binding is a method of binding pages together using a continuous plastic or metal coil that is threaded through holes punched along the edge of the pages. This type of binding allows the pages to lay flat when open, making it ideal for notebooks, reports, and presentations. The spiral coil can be easily manipulated, allowing for the addition or removal of pages as needed. This binding technique is popular in both personal and professional settings due to its durability and flexibility. Spiral-bound materials are often used in educational environments, as they can withstand frequent use and provide easy access to information.
