Researchers at Virginia Tech have adapted the Ancient Japanese art of kirigami to make clear tape 60 times stronger, yet still removable. The technique involves cutting a series of U-shaped incisions across the adhesive strip, which forces the separation path to go backwards at specific locations and makes the adhesive very strong. But when the tape is peeled in the opposite direction, it always goes forward, making it easy to remove. The kirigami technique improved the bond of every type of tape tested, from packaging to medical tapes, according to the team's research, which was published in Nature Materials.
