When peeled in one direction, the adhesive tape exhibited 60 times greater adhesive force than unmodified tape of the same type. However, when peeled in the opposite direction, it was easily peeled off.
This unique behavior, known as crack backpropagation, allows the creation of strong yet easily peelable tapes. In lab tests, kirigami-cut tape outperformed conventional tape with improved tape-sealed boxes that survived at least five drops from height.
This technology can find applications in packaging, robotic grippers, wearables and processed products.
