Plastic binding is a method used to hold together multiple sheets of paper or other materials using a plastic spine. This spine is typically made of flexible plastic and comes in various colors and sizes, allowing for customization. The sheets are punched with holes, and the plastic spine is threaded through these holes, securing the pages in place. This binding technique is popular for creating reports, presentations, and manuals because it is durable and allows pages to lay flat when opened. Additionally, plastic binding is often used in schools and offices due to its affordability and ease of use.
