Velo binding is one of the most secure binding methods available—once the pages are locked in using a heat seal method, they can’t be unbound or tampered with. We sell several hot knife velo binding machines, as well as 11 pin, 11-inch binding strips. Velo binding is very useful for legal documents, theses and dissertations, and documents that aren’t meant to be tampered with. Velo binding is durable, professional-looking, especially when used in conjunction with one of our many cover options.
