When binding a notepad together what process is used?

When binding a notepad together, various processes can be used, such as spiral binding, staple binding, or perfect binding. Spiral binding involves threading a plastic or metal coil through holes punched along the edge of the pages. Staple binding uses staples to secure the pages together at the spine, while perfect binding involves gluing the pages and cover together along the spine for a more polished look. Each method offers different durability and aesthetic qualities.
