Lamination inks for food retort packaging

Flint’s VarioLam RT for flexo and gravure

July 2, 2015

Flint Group has introduced 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 products – RTF, signifying the flexo ink system; and 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. A full line of colors have been formulated to provide high color strength, excellent re-solubility, 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 high lamination bonds and final retort bonds.
