In addition to creating a sturdy bond with corrugated cartons, water-activated tape offers cohesive strength, which measures the tape’s ability to maintain its seal on the carton under stressful conditions.
Consider this: your carton will encounter external forces throughout its lifecycle, whether climatic, lifting, shifting, and general stress applied during storage and transit. When the carton is met with these external forces, the exterior of the carton will contort and apply stress to the tape, typically where the major flaps meet the side of the carton.
If the tape’s cohesive strength is not sufficient, it will fail. This can lead to cartons opening, and the potential for product damage, contamination, and theft.
