Common Applications

Whether industrial printers rely on high-volume flexo production or shorter runs using thermal inkjet or piezo inkjet systems, Kao offers numerous ink options for printing high-quality package designs and marking and coding, depending on the cardboard material and intended results.


Inks for Printing Cardboard

Our inkjet and flexo cardboard inks are widely used to print primary and secondary packaging for e-commerce, food, beverage, pharmaceuticals, and other consumer or industrial products. For marking and coding, our high-opacity inks produce 2-D coding for reliable scanability. Our process and spot-colour formulations deliver vibrant results for visually distinct package designs.

Benefits for Corrugated Printing

Water-based Inks

These cost-effective inks offer superior dry time and richer blacks. The water-based pigment inks have better lightfastness and high durability. Our eco-friendly nanodispersion water-based pigment ink has the added advantage of printing on non-porous materials.

Curable inks

Our UV, LED, and EB curable inks for non-porous paperboard materials deliver vibrant colours for packaging design. These rapid-curing inks are durable and resistant to chemicals and environmental exposure. The EB-curable and low migration UV/LED curable inks may be suitable for fast-moving consumer goods (FMCGs), including foods, pharmaceuticals, and health and beauty products.

Sustainable Inkjet Inks and Flexo Inks

Kao strives for production and manufacturing methods that reduce the impact on the environment, including formulation of special inks that contribute to increased sustainability.


This nanodispersion water-based inkjet ink is eco-friendly and specifically designed for printing on flexible packaging, thin films and other non-porous materials.

Bio-based Mineral-Oil-Free

This eco-friendly inkjet ink is an alternative to conventional oil-based inkjet inks. The ink offers high performance on porous substrates such as corrugated cardboard and other paperboard materials.


We offer water-based and solvent-based flexo inks that are certified for industrial composting. Both of these inks are suitable for printing on non-porous materials.
