New FCM UV-ink systems by Zeller+Gmelin

Printing of food packaging in accordance with stricter legal requirements

Increasingly stringent legal requirements raise the demands on the production of legally compliant food packaging. Therefore, the correct choice of printing ink and varnishing systems is all the more important.

Based on current developments and the latest raw materials, Zeller+Gmelin present the appropriate solution with the new generation of low migration FCM UV-printing inks for printing on food packaging and labels.

The new ink systems contain significantly less substances which are critical to migration. Together with the use of special cross-linked initiators, Zeller+Gmelin have minimized the risk of migration.

1) UV Standard 2) Zeller+Gmelin FCM inks

The molecular weight of the cross-linked photoinitiators (approx. 1000 Dalton) exceeds that of conven-tional photoinitiators (< 400 Dalton) by quite some way. In addition, they contain polymerizable groups which participate in the curing and are thus firmly incorporated in the chemical structure of the printing ink film. These features make the new FCM-system by Zeller+Gmelin tremendously secure!

FCM

Everyone talks about migration! We don’t, because with our technology migration is so largely avoided that we talk about FCM UV-inks. FCM means that the printing inks are suitable for food contact material.

This is also the way EuPIA defines it, so we have adjusted our product name accordingly so that every customer knows that our products meet these guidelines, since there are different standards across the world.

Attention: According to the definition, the ink must not come into direct contact with food!

Low migration UV flexo printing for food packaging

UVAFlex® FCM Y81 – reliable, safe and highly efficient Very safe against migration, extremely low in odour and free from BPA: With these properties, the fourth generation of low-migration FCM UV-flexo printing inks from Zeller+Gmelin are convincing. Their strengths are reflected in the printing on paper and foils for labels, folding boxes and flexible packaging.

UVAFlex® FCM Y81 – now completely free from BPA!Zeller+Gmelin have developed this latest generation of FCM flexographic printing inks for food packaging without BPA-containing raw materials. Thus, the UVAFlex® FCM Y81-ink series meets the requirements of the current Nestlé Guidance Note dated September 2016.For printing on food packaging, the UVAFlex® FCM Y81-inks are suitable for almost any application: they are universally applicable on paper and foil.

UVAFlex® FCM Y81 – mit hervorragender Druckperformance!The new UVAFlex® FCM Y81 printing ink series is characterized by homogeneous machine behaviour, excellent printability featuring a stable viscosity and very good flow properties, thereby significantly reducing the risk of ink spitting – even at high machine speeds. The ink series guarantees higher performance at less ink consumption and enables the combined printing of screens and solids by printing with a reduced cell volume of the anilox roller!

Customer test phase / technical data

During an intensive test phase, the new UVAFlex® FCM Y81 ink series has been extensively checked and tested by international customers and partners!

Positive feedback

Negative feedback

We generated a very high return and the test partners provided a very positive feedback with regard to:• high reactivity• high colour density and strength• very good printing performance• easy handling

Ink densityCompared to our previous ink series Y71, the colour density was significantly increased in the new UVAFlex® FCM Y81-series!

CuringThanks to the new technology, the UVAFlex® FCM Y81 showed extraordinary curing properties with very low energy input during the customer test phase.

The new FCM-technology by Zeller+Gmelin makes the colour series not only enormously secure, but also very interesting from an economic point of view!

ViscosityThe viscosity was another important main focus in the customer test phase. The new ink series showed a low and stable viscosity with very good flow characteristics significantly reducing the risk of ink spitting.

Mixing with monopigmented ink mixing systems

Following many years of positive experience using monopigmented ink mixing systems, Zeller+Gmelin offers a monopigmented ink mixing systems for the new UVAFlex® FCM Y81-Series, too.

Advantages• PANTONE® shades are easier to match• Ink mixes have higher colour strength and are purer, because only the necessary pigments are used for the mixture• The higher colour intensity makes printing with reduced ink lay-down possible• Reduced dot gain in halftone printing• More flexibility when adjusting colour strength for special shades• Less colour deviations between reference sample and mixed ink under changing light sources (metamerism)• The colour communication between ink manufacturer and its customer will be easier and faster by the usage of monopigmented ink mixing systems• Mixing recommendations are available for all PANTONE® mixed shades• Ink dispensing, mixing and measuring systems with different expansion levels are available• Reduction of stock expenses• Lower disposal charges by elimination of leftover inks

In our production plants we work with the same monopigmented ink mixing systems. This guarantees a fast and effective colour communication between ink manufacturer and printer.Regardless of whether PANTONE® spot colours or other colour systems have to be mixed, with our high-pigmented ink mixing systems you will always get the best possible results. Additionally, customer shades which are independent from a reference-guide can be optimally matched.
