Wire binding is a method of binding documents using a metal wire loop. This technique involves punching holes along the edge of the pages and threading a continuous wire through these holes. The wire is then twisted to secure the pages together, creating a sturdy and professional-looking finish. This binding style is popular for reports, presentations, and manuals because it allows the pages to lay flat when open. Additionally, wire-bound documents can be easily flipped and turned, making them user-friendly. Wire binding is available in various sizes and colors, catering to different aesthetic preferences and functional needs.
