Brand owners, take notice. INX International Ink Co. is now the first and only ink company in the metal decorating segment to receive a Gold level Material Health Certificate from the Cradle to Cradle Products Innovation Institute (C2CPII), in collaboration with the Environmental Protection Encouragement Agency. Intended for use on beverage cans, the AP EcoCan 2-piece metal ink system achieved this status after INX standard AP series inks had already earned bronze level certification.
