Eco-friendly Inkjet Ink for Flexible Film


LUNAJET is a water-based, pigmented inkjet ink that uses a proprietary technique known as nanodispersion. It is especially suited for printing on flexible film substrates. Besides being safe for food packaging, eco-friendly LUNAJET produces extremely low amounts of VOCs, which significantly lowers its impact on workspaces and the global environment.

No UV curing. No odors. No damage to the substrate.

Common Applications

Beverage squeeze bottles Thin films
Resealable flexible food packaging Glossy paper

More About LUNAJET Ink




Water-based inks are entirely free of PVC resin or plasticisers and are also entirely free of harmful ozone-depleting chemicals and aromatic hydrocarbons.

Safer for Health (Non-Toxic)

Free from harmful chemicals, water-based inks are safe not just for the environment but for employees. There are no harsh chemicals or solvents that the user can inhale.

Higher Quality Prints

Because they sit deeper within porous substrates, water-based inks can produce longer-lasting prints with impeccable detail, with much more defined, sharper edges. This includes half-tones and more, making them the perfect choice for printing intricate, detailed designs.


Water-Based Flexo Inks

The many flexo water-based high-performance inks handle high-speed printing of substrates ranging from corrugated cardboard to biodegradable films, which takes our IDROSTAR* OK COMPOST ink.

Common Applications

Corrugated boxes Flexible packaging
High-gloss paper labels Low weight paper
Food packaging paper Films

*The IDROSTAR OK COMPOST flexo ink has been certified by TÜV® Austria.
