Japan-based Toyo Ink has developed a new range of electron beam (EB) curable and volatile organic compound (VOC) free flexo inks.
Suitable for flexible and carton packaging applications, the new Elex-one inks are designed to address environmental and safety issues, as well as regulatory requirements.
According to Toyo Ink, the newly developed inks do not evaporate or volatilise on the printing press and remain consistent during processing.
Furthermore, EB inks feature no solvents or photoinitiators and are safe from chemical migration, making it a non-hazardous material suitable for use in food packaging materials and sanitary products.
Toyo Ink president and CEO Katsumi Yamazaki said: “Many of the EB flexo inks out on the market today contain small traces of solvent that is chemically added into the ink during the curing process.
“The Elex-one series was specially formulated by Toyo Ink engineers to cure using only EB irradiation — without the addition of a volatile component.
“As a result of this, we are able to offer a completely VOC-free solution that still provides the high print quality and performance results that are our customers require.”
Elex-one has been tested for use in the European market, which is witnessing an increasing demand for VOC-free inks.
Once approved, Toyo Ink plans to commercially release the product in the region, with a plan to release the same in other markets.
In September, Toyo Ink announced the development of its two new series of low-energy, ultraviolet (UV)-curable offset inks under its Flash Dry brand.
