Eco Printing Solutions

Eco printing solutions address four environment-friendly perspectives.

  • Work environment
  • Safe materials
  • Resource conservation
  • Emissions  reduction


Sustainable Inkjet Inks

Kao develops eco-friendly inkjet inks for sustainable printing. We established new standards for formulating eco-friendly inkjet inks through our research and development on sustainable printing technology. We strive to decrease environmental impacts for carbon dioxide emissions, VOCs, waste, landfill use, and harmful by-products.


LUNAJET, a Water-based Pigmented Inkjet Ink

This high-quality water-based pigmented inkjet ink using nanodispersion technology makes it suitable for non-porous substrates and sustainability. LUNAJET, formulated for Piezo technology, is eco-friendly and safe to use in plastic film printing for food, health and beauty, and pharmaceutical products.


Our LUNAJET ink provides unique advantages for industrial printers needing water-based inks.

Suitable for food-grade packaging

LUNAJET ink remains flexible with no cracking or breaking. There is no damage to the substrate. No UV curing. No odours.

Minimises emissions of volatile organic compounds (VOCs)

Low volatile organic compounds, which are harmful to the environment and humans.

More environmentally friendly

As a water-based ink, there are no photoinitiators requiring mercury arc lamps for curing.


Common Applications

  • Pharmaceuticals
  • Pet foods
  • Health and beauty
  • Food and beverage

Bio-based Mineral-Oil-Free

Bio-Based Mineral-Oil-Free (MOF) inkjet inks for piezo printing technology offer an eco-friendly alternative to oil-based inks for the marking and coding of porous paper and cardboard secondary packaging.

These certified eco-conscious inks meet compliance requirements for increasingly stringent environmental legislation and regulations around the world.


Our Bio-Based MOF ink provides unique advantages for industrial printers using mineral-oil-free inks.

High Performance and Reduced Risk

MOF inks for porous substrates offer low-maintenance performance, ensuring maximum production uptime and print performance.

No hazardous pollutants (HAP)

MOF inks reduce the risks associated with mineral oil ink contamination in the food packaging industry.

Near-zero VOCs

Near-zero volatile organic compounds, which are harmful to the environment and humans.


As a biodegradable ink, MOF ink is compostable, which supports sustainability.

Reduce the carbon footprint

MOF ink reduces CO2 emissions released during the industrial printing process, lowering the carbon footprint.

Reduce the reliance on fossil fuel materials

MOF inks are free of fossil fuel materials, which have been linked to atmospheric pollution, global warming, the release of toxins into the environment, and health problems.


Common Applications

  • Food Packaging
  • Pharmaceutical Packaging
  • Health and Beauty


Flexographic Inks

Our water-based and solvent-based eco-friendly flexo Inks are suitable for polyolefin and polyester media treated with adhesives with or without solvent. This ink series is designed for lamination printing, and it stands out for its resistance to temperature and grease. It also has certified OK COMPOST for printing on compostable and biodegradable media.

OK Compost Flexo Inks

These inks have been awarded the “OK Compost” certification from TÜV Austria, which guarantees the product as biodegradable in an industrial composting plant.
