Select Materials for Water-based Folding Carton Inks
Folding cartons are used to pack a wide range of end products, from soft drink beverages to cigarettes and tobacco. They are typically printed by Gravure
and utilize multiple colors and
Inks for folding cartons need to be formulated with moderately high gloss
surface rub resistance. Specific modifications to these ink formulations include:
- The modification to C.O.F. (slip) values
- Product resistance (water, alcohol, detergent etc…) and
- Heat resistance.
In general, increase in wax
levels increases rub resistance and slip values (lowers C.O.F.). Waxes can also have an impact on
other surface properties like water and soap resistance.
Typical substrates for folding cartons
include paperboard and small flute corrugate Solid Bleached Sulfate (SBS).
