Kao Collins has announced two new developments to Sigma – its TIJ ink for HP 45si industrial printing systems.

The ink, first released in 2019, has a 12-hour decap time with a 24-month shelf life and is compliant with Swiss Ordinance Annex-10 Chemists at Kao Collins. All new Sigma inks meet the requirements specified in Annex 10 of the Swiss Ordinance.

Kristin Adams, Kao Collins’ marketing manager, said, ‘Focusing on the future is at the core of our business, which means staying ahead of global regulations. We wanted to give our customers and the industry a competitive advantage without being required to do so.’

The new Sigma inks, packaged in HP cartridges and now available in several colours, are formulated and manufactured in accordance with the “EUPIA” Guideline on printing inks applied to the non-contact surface of consumer packaging such as pet foods, pharmaceuticals, nutraceuticals, beverages and more.

Kao Collins now offers Sigma in five colours: red, yellow, blue, green, and violet. The inks print on non-porous substrates used for flexible packaging, rigid plastics, and metals, including nylon BOPP, PE, PET and PP, foils, aluminum, and laminated papers.
