Expert Commentary
The benchmark for Unwind Force of Pressure-Sensitive Tapes. This measures the effort required to pull tape off the roll. The technical requirement is a constant Unwind Speed and a low-friction spindle. MTO’s Tape Unwind fixture attaches directly to our 5kN frames, allowing for the characterization of the adhesive’s Release properties. For engineers, this is a process-control metric; if the unwind force is too high, it can lead to tape stretching or machine snapping on automated packaging lines.
