The Sticky Science of Pressure Sensitive Tapes
From a simple office supply to a crucial component in high-tech manufacturing, pressure sensitive tapes (PSTs) have become indispensable. Their unique ability to adhere to a surface with only light pressure, without the need for solvents, water, or heat, makes them incredibly versatile. These tapes are not a one-size-fits-all solution; they come in a vast array of formulations to serve a wide range of industries, including packaging, automotive, electronics, and medicine. The science behind them lies in the careful balance of adhesive chemistry and backing material, which together determine the tape's tack, adhesion, and holding power.
A key innovator in this market is Henkel AG & Co. KGaA, whose Adhesive Technologies business unit is at the forefront of recent developments. Henkel has been particularly focused on sustainable and high-performance solutions. For example, at Labelexpo Europe 2025, the company showcased its portfolio of recyclable pressure-sensitive adhesives that help companies comply with new regulations and improve circularity. This includes wash-off PSAs for PET bottles and repulpable adhesives for paper labels. Henkel is also advancing high-performance PST solutions, such as UV-curable adhesives that offer excellent energy efficiency and resistance to demanding environmental factors, making them ideal for applications in the medical and graphics industries. The company's commitment to research and development underscores the ongoing evolution of pressure sensitive tapes to meet modern market demands.
