Spiral binding is a method of binding pages together using a continuous plastic or metal coil. This coil is threaded through holes punched along the edge of the pages, allowing them to turn easily. It is commonly used for notebooks, reports, and manuals, providing a flexible and durable way to keep documents organized. One of the main advantages of spiral binding is that it allows pages to lay flat when open, making it easier to write or read. Additionally, it can accommodate a variety of page sizes and thicknesses, making it a versatile choice for both personal and professional use.
