How does Signet's Kraft Water Activated Tape work?

Signet's Kraft Water Activated Tape uses a combination of moisture and a starch-based adhesive (eco-glue) to create a secure, strong, and 100% eco-friendly seal. It can be applied by running a wet cloth or sponge over the tape or by using a Water Activated Tape Dispenser. The moisture activates the starch-based adhesive to penetrate the fibres of the carton/cardboard to secure your package. It's effective, easy to use and most importantly, very efficient.
