ULTRASEAL forms are created from a single sheet of paper. They are a cost-effective, labor-reducing and environmentally-friendly way to create, process and deliver mailed pieces without an envelope or glue. ULTRASEAL forms are also tamper-evident, which makes them the perfect solution when you want to be sure that the end recipient is the only person opening the mailer. We recommend you pair our ULTRASEAL forms with compatible Formax pressure seal equipment.
