Flint Group launches VarioLam RT, retort lamination ink for the North American flexographic and rotogravure packaging market

Friday 10. July 2015 - Flint Group is delighted to announce VarioLam RT, a retort lamination ink system for the North American flexographic and rotogravure packaging market.

VarioLam RT provides a single ink system technology that does not require cross linkers to provide high bond strengths on a wide range of film structures. VarioLam RT consists of two product names:
? RTF – signifying the flexo ink system;
? RTG – signifying the rotogravure ink system.
These flexo and rotogravure inks will enable the printing of high definition graphics that can withstand the heat and pressure of the retort process that allows extended shelf life of food products.
Timothy Wagner, Product Manager, Flexible Packaging North America, explains, “Our goal at Flint Group is to provide best in class products to the market. We identified that Flint Group needed to develop a retort ink system that would meet four critical areas: the system needed to be non vinyl based, and use a standard solvent package – no MEK was allowed. The system could not utilise any cross-linkers, and finally had to be designed with the goal of meeting 1500 fpm minimum.”
Mr. Wagner concludes, “VarioLam RT meets the four criteria and we are pleased to provide this product to North America.”
A full line of colours have been formulated to provide high colour strength, excellent resolubility, and good flow at low viscosities. VarioLam RT delivers excellent adhesion on corona treated PET, acrylic coated PET, AlOx coated and SiOx coated PET, and nylon films. VarioLam demonstrates its performance through its outstanding high lamination bonds and final retort bonds.
VarioLam RT is commercially available now
