Thermal binding covers are a type of binding solution used to securely hold together printed documents. They consist of a plastic cover with a heat-sensitive adhesive on the spine. When heated, the adhesive melts and binds the pages together, creating a professional-looking finish. These covers come in various sizes and colors, making them suitable for different types of projects, such as reports, presentations, and portfolios. They are easy to use, requiring only a thermal binding machine to apply heat and secure the documents, making them a popular choice for offices and schools.
