BASF offers Irgacure 270 cationic photoinitiators for packaging inks. Irgacure 270 now makes it possible to combine fast UV curing with very low emissions. This new product is very versatile, and its applications include both UV-curable printing inks and clear overprint varnishes, according to the company. Irgacure 270 is a new high-molecular-weight sulfonium salt which fulfills the high standards that UV-curable inks for food packaging are required to meet. Extensive tests have shown that emissions and migration are both very low. Irgacure 270 is mainly employed in UV-curable applications that demand low emissions. These include clear overprint varnishes, flexographic inks, screen inks and inkjet inks for printing food packaging made from a variety of substrates such as paperboard, plastics and metal.
