Water-Activated Tape (WAT)

Made primarily of white or natural color (Kraft) paper and starch-based adhesive. Usually available in various widths and thicknesses. Might contain multiple layers with fiberglass reinforcement. When the adhesive is activated with water, it penetrates the carton material and the tape forms a permanent bond with the carton.
