Toyo Ink Brasil, a member of Japan’s Toyo Ink Group, has introduced new range of polyurethane (PU)-based inks for laminated packaging applications.

The firm’s new upgraded lineup of high-performance surface and lamination inks are intended for flexo and gravure printing.

Toyo Ink Brasil director Sergio Pera said: “With Latin America being a key segment for flexible packaging, we are looking to boost our presence in this important market.

“Demand continues to grow for packaging solutions that offer greater convenience features, stronger barriers, and lighter weight materials, and for shorter print runs.

“For this reason, we have been working closely with our customers to improve our range of polyurethane resin-based inks to meet their requirements for greater versatility, performance.”

Toyo Ink Brasil provides a broad range of systems ranging from general-purpose snack structures to high-end retort and hot-fill packaging applications.

The new line of PU-based lamination inks includes the general-purpose LIOTECH solvent-based flexo and gravure systems.

Additionally, the new inks range comprise the LIOVALUE solvent-based gravure series, REXTA solvent-based flexo series, the AQUAECOL water-based gravure series and the AQUA LIONA water-based flexo series for general up to high-end retort applications.

The company said its PU lineup, based on the firm’s unique pigment dispersion system, offers high color density for a wider color gamut and enhanced bond strengths.

The new range of inks, which leverage the company’s advanced cross-link technology for polyurethane resins, allows converters to engineer packaging structures featuring superior heat resistance, content resistance and low solvent retention for very low odor.

Toyo said that the new inks are ideal for printing on a wide range of substrates, such as corona treated OPP, PET, Nylon, without a primer or any other chemical treatment.

The low glass-transition temperature of the special PU resins allows the inks to offer improved stress-relaxation capability, the firm noted.

Toyo said in statement: “This is essential in avoiding delamination during the retort process, when the different layers of laminated packaging structures expand or contract due to temperature changes.”
