Water activated gum tape requires water to activate its adhesive properties.

The tape is made of kraft paper with a water-activated starch based adhesive on one side. To use the tape, the user wets the adhesive side of the tape with a moistened sponge, brush, or dispenser. This activates the adhesive and makes the tape sticky. The tape is then applied to the surface to be sealed and pressed down firmly.

Once the tape has been applied, the adhesive begins to bond with the surface and becomes increasingly strong over time. Water activated gum tape creates a strong, tamper-evident seal that is difficult to remove without damaging the packaging or leaving evidence of tampering.

Water activated gum tape is a popular choice for packaging and shipping applications because it provides a secure and reliable seal that can withstand rough handling, extreme temperatures, and moisture. It is also an eco-friendly option because it is made from renewable materials and can be recycled.
