“Over the last years intensive laboratories researches brought polyurethane (PUR)-based color inks to be used in flexo printing opening to this technology new possibilities previously reserved only to gravure printing,” says Thomas Bastian, Marketing Director at Siegwerk. “PUR inks exhibit excellent printing results and can be universally applied to a very wide range of substrates. OPP, pre-treated PET, as well as OPA, barriers films coated with SiOx and AIOx can be printed directly with PUR inks.”
