Flexible packaging
Effect pigments, aluminium pigments, gold bronze pigments, vacuum metallized pigments, press ready inks, offset inks, flexo printing ink
Printed plastic substrates are not only used for food packaging (see food packaging), but also in the “non-food” area as outer packaging, as carrier bags, shrink wrap (including “shrink sleeves”) etc. For food packaging, compliance with the relevant regulations with respect to migration properties (no risk) is required.
Gravure and flexo printing with solvent-based or UV curable inks are the most frequently used processes. The emergence of so-called “convenience food” has brought about new boom in this segment.

Decomet®

Decomet® is the product name for vacuum metalized pigments (VMPs) by SCHLENK. The manufacturing process makes these pigments extremely thin, and in appearance they are extremely smooth and highly reflective when being applied on foils.
Decomet pigments can be used in sheetfed offset, gravure, flexo and screen printing inks. They can achieve effects similar to those produced with metalized substrates and foils, and because they are non-leafing, the effects can also be tinted with color pigments. Special compositions for water-based and UV curable inks complete the range of this highly attractive product range.
