Water-Activated Reinforced Kraft Paper Tape is a moisture-activated adhesive tape constructed from kraft paper with embedded fiberglass filament threads running between its layers. Its specially formulated adhesive is triggered by the simple application of water, after which it creates an exceptionally secure bond with cardboard surfaces — one that cannot be broken without visibly tearing or destroying the tape itself. The high-tensile kraft paper sheets lock the ultra-durable fiberglass strands firmly in place, delivering superior structural integrity and an added layer of tamper-evident security.
