PU inks refer to thermoplastic polyurethanes (TPU) used in printing applications. These inks are designed for flexographic and gravure printing, providing properties such as flexibility, adhesion, and resistance to heat and water. They are often used in combination with other materials to enhance printing performance and reduce the use of restricted substances.
