High quality printing inks for packaging
Printed packaging is a ubiquitous and indispensable part of our daily lives. In recent years, packaging has increasingly become the focus of public attention, which has led to new requirements and trends that continue to change the packaging market. The demand for innovative and sustainable packaging concepts is constantly growing. The printing ink plays an important role here.
We offer you high-quality printing ink systems and work with you to develop customer-specific solutions that meet the requirements placed on color performance and packaging functionality throughout the entire production process. Our UVAFLEX and UVALUX ink series set the market standard for UV/LED flexo and offset printing inks in the FCM and non-food sectors. With their modern formulations, they meet all NESTLE and SWISS LIST; EUPIA and GMP requirements and are particularly suitable for demanding applications such as wine labels on uncoated papers, self-adhesive labels or packaging materials for wrap-arounds or shrink sleeves. Zeller+Gmelin shines with its leading quality of reactive-curing FCM and NON-FCM printing inks and varnishes, backed by comprehensive specialist and application knowledge. Our printing inks skillfully set the scene for brands and packaging. It is not for nothing that renowned branded companies all over the world trust us.

Modern FCM technology
In line with stricter legal requirements for printing on food packaging
Ever stricter legal requirements are increasing the demands for the production of legally compliant food packaging. The right choice of ink and coating systems is therefore all the more important.
Based on current developments and the latest raw materials, Zeller+Gmelin presents you with the right solution. Modern FCM ink systems contain significantly fewer migratable substances. Together with the use of special networked initiators, Zeller+Gmelin has minimized the potential for migration. The molecular weight of the cross-linked photoinitiators (approx. 1000 Daltons) is several times higher than that of conventional photoinitiators (< 400 Daltons). They also contain polymerizable groups that participate in the curing process and are thus firmly integrated into the chemical structure of the printing ink film
. These properties make the FCM systems from Zeller+Gmelin extremely safe!
Our FCM technology is more than just "low migration". It is characterized by its high-quality composition, coupled with the highest requirements and lowest migration behaviour, as well as excellent printing properties.
The advantage of conformity
- Nestlé Standard St-80.001 (Printing Inks for Food Packaging)
- Without bisphenol A and raw materials based on bisphenol A
- Swiss Commodities Ordinance 817.023.21
- GMP Regulation (EU) 2023/2006
- EU Regulation 10/2011 in its latest version

LED technology
As a specialist for radiation-curing printing ink systems of the highest quality, we also offer high-quality printing ink in the field of LED UV technology.
LED technology is particularly interesting for environmentally conscious companies that not only want to conserve resources but also protect the environment. LED technology offers an economic and ecological advantage.
LED technology has developed into a true alternative solution in the field of
radiation curing!
In principle, the polymerization process of an LED ink is identical to that of a UV system. The difference is that an LED system dries with a specific wavelength. The cross-linking reaction is therefore triggered by excitation in a very narrow wavelength range. Industrial LED systems can operate in a wavelength range from 365 nm to 405 nm. The most common systems are those that emit at 385 nm or 395 nm.
Environmentally friendly + sustainable
Our printing inks are highly reactive systems which, thanks to their formulation, do not require any kind of volatile raw materials. This makes our printing inks solvent-free and emission-free! LED technology also completely eliminates the need for mercury vapor lamps. This means that you no longer have any mercury in your production process and are therefore protecting the environment. By using a specific wavelength when using LED spotlights, no ozone is produced on the machine, the heat input is reduced to a minimum and no critical UV-C radiation is emitted. This makes our LED ink solutions a user and environmentally friendly system!
- No ozone formation
- mercury-free technology
- No critical UV-C radiation
- Minimal heat input
- Low energy requirement
Profitable + Powerful
LED lamps are ready for immediate use, eliminating standby and heat-up times. You can operate the lamps in "switch on-switch off" mode and thus clock your processes. In addition, LED units can be partially switched due to their design. This enables LEDs that are not required to be switched off outside the print area. LED lamps also have a much longer service life without any loss of power. This extends maintenance cycles many times over.
- High efficiency
- Long service life
- No loss of performance
- Zone switching
- tactile
- No warm-up time
- No standby time
Analytics Center
Zeller+Gmelin has an in-house analytics center that was set up specifically for the development of low-migration inks, for raw material controls and for the internal testing of test samples.
We now also have the option of liquid chromatography with a high-resolution quadrupole time-of-flight mass spectrometer for even more precise and sensitive analyses. In addition, we always have our low-migration ink series tested and evaluated by independent analysis institutes. This double testing enables us to offer printers, packaging buyers and consumers the greatest possible product safety.
Numerous analyses have shown that when used properly with our low-migration ink series, the legal limit value of 10 ppb can not only be safely adhered to in migration tests with 95% ethanol, but can also be significantly undercut.
- Liquid chromatography with high-resolution quadrupole time-of-flight mass spectrometer (LC-QToF-MS)
- Gas chromatography with mass spectrogram (GC-MS)
- Liquid chromatography with mass spectrogram (LC-MS)
- Quality control of the raw materials we use
- Internal evaluation of test samples
Mixing with Z-Base Colors
Based on years of positive experience with monopigmented color mixing systems, we offer a monopigmented color mixing system for all our color series.
Advantages
- PANTONE® tones can be blended better
- Color mixtures are more colorful and purer, as only the pigments actually required for a color mixture are used
- the higher color intensity enables printing with low layer thicknesses
- Reduced dot gain in halftone printing
- Greater flexibility when setting the color intensity of spot colors
- fewer color shifts when viewing the printed products under different light sources (metamerism)
- Color communication between the color manufacturer and the customer is simpler and therefore faster thanks to the use of monopigmented mixing systems
- Mixing recommendations are available for all PANTONE® shades
- Color formulation, mixing and dosing systems are available in various expansion stages
- Reduction of storage costs
- Lower disposal costs for leftover paint
We work with the same monopigmented
color mixing systems in our production facilities. This ensures fast and effective color communication
between the manufacturer and the print shop. Regardless of whether PANTONE® spot colors or other common mixing color systems need to be mixed, our highly pigmented
color mixing systems always achieve the best possible result. Even fan-independent shades can be optimally adjusted.
