Advance - Printing Inks
Printing inks provide graphics and aesthetic appeal. They can be applied to the lidding material by letterpress, gravure, offset, flexographic, or silk-screen printing processes. Printing inks must resist heat sealing temperatures as high as 300 ºC without showing any discoloration or tackiness (blocking). In
addition, they must sufficiently resist abrasion, bending, and fading and must be safe for use with the intended product. Printing inks should not contain excessive amounts of hydrocarbon lubricants, greases, oils, or release agents.
