Flexography (often abbreviated to flexo) is a form of printing process which utilizes a flexible relief plate. ... It is widely used for printing on the non-porous substrates required for various types of food packaging (it is also well suited for printing large areas of solid color).

 

Flexography is a modern version of letterpress printing. This traditional method of printing can be used on almost any type of substrate, including corrugated cardboard, cellophane, plastic, label stock, fabric, and metallic film. The flexographic printing process uses quick-drying, semiliquid inks. In this age of digital printing, flexography holds its own in the areas of large orders and long print runs, particularly of packaging products and labeling.
