“With Latin America being a key segment for flexible packaging, we are looking to boost our presence in this important market,” said Sergio Pera, director of Toyo Ink Brasil. “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.”
The new line of PU-based lamination inks offered by Toyo Ink Brazil includes the general-purpose LIOTECH solvent-based flexo and gravure systems. For general up to high-end retort applications that require excellent content resistance, the company has available the LIOVALUE solvent-based gravure series, the REXTA solvent-based flexo series, the AQUAECOL water-based gravure series and the AQUA LIONA water-based flexo series.
The new range of inks also leverages the company’s advanced cross-link technology for polyurethane resins, making it possible for converters to engineer packaging structures that exhibit superior heat resistance, content resistance and low solvent retention for very low odor. These systems are well suited for printing on a wide range of substrates, such as corona treated OPP, PET, Nylon, without a primer or any other chemical treatment.
Moreover, thanks to the low glass-transition temperature of its special PU resins, Toyo Ink Brazil was able to develop inks that demonstrate excellent stress-relaxation capability. 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.
