Europe: Toyo Ink releases inks for food-safe packaging

SHARE

Toyo Ink has developed the Elex-one series of EB (electron beam) curable flexo inks, which is VOC-free, making it an ideal solution for food-safe flexible and carton packaging applications.

The flexible package printing market has seen growing interest from package printers and converters in volatile organic compound (VOC)- and carbon dioxide-reducing technology, due to increased environmental and safety concerns, and regulatory requirements.

Demand is particularly strong in North American and European markets, where flexo inks based on solvent materials are mainstream technologies.

The company says since the drupa exhibition in Germany (May 2016), industry demand for both water-based flexo and EB-curable flexo has been gaining momentum in these regions.

“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,” said Katsumi Yamazaki, president and CEO.

“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.”

EB flexo inks do not evaporate or volatilize on the printing press, so the ink does not change in consistency during processing.

Since ink curing does not occur on the plate, stable print quality can be achieved even over long runs.

In addition, EB inks are highly safe from chemical migration in that its composition is free of solvents or photoinitiators, making it a non-hazardous material suitable for use in food packaging materials and sanitary products.

Elex-one is currently undergoing trial testing for the European market.

Once approved, Toyo Ink plans to begin the commercial release of the product in the region.

Subsequent launches into new markets are expected once the company establishes a foothold in Europe.
