Gummed Tapes with a flat back and a strong synthetic rubber adhesive. Packaging as well as a number of aesthetic uses including silk screening, picture framing, splicing, and tabbing are all possible with it. The link between the carton and tape forms a permanent carton seal once the tape has been activated with water. Gummed Tapes immediately attach to the carton when used with a tape machine, making it simple to reliably seal overfilled boxes. They are very safe and great to use.
