To use water activated gummed packaging tape, you’ll need to apply moisture/water to the bottom (non-printed side) of the tape. You can do this manually by using a wet sponge (included with your order) or by using a tape machine/dispenser (sold separately).
Water activated tape (WAT) is used to securely close boxes in a single strip. The tape bonds to corrugated boxes to keep the contents inside safe during transit and shows evidence of any tampering or opening.
