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.

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.

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!

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.

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.

Based on years of positive experience with monopigmented color mixing systems, we offer a monopigmented color mixing system for all our color series.

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.
