Siegwerk launches Sicura Litho Pack Eco

Siegwerk has launched Sicura Litho Pack Eco, a new sustainable UV offset ink series for non-food paper and board applications

Siegwerk has launched Sicura Litho Pack Eco, a new sustainable UV offset ink series for non-food paper and board applications, formulated with high bio-renewable content, providing an environmentally friendly alternative to standard UV inks.

The formulation of the new series consists of more than 40 percent of renewable and vegetable-based components showing a four times higher share of bio-renewable content than the average standard UV ink. 

Furthermore, the series is free of TMPTA, Benzophenone as well as CMR CAT. 1 and CMR Cat. 2 components. It is a low odor ink series specially designed for all kinds of paper and board substrates. 

Sicura Litho Pack Eco is suitable for all non-food packaging applications where special attention is paid to the packaging’s environmental impact and circularity. The series shows excellent ink performance and a high color strength. Next to high dot gain sharpness and excellent flowability, Siegwerk’s new UV offset range offers a very stable ink/water balance even during long runs as well as a good film flexibility for post-processing. 

The product range contains four color process inks according to ISO, Pantone colors, base inks, special colors as well as flexo OPV.

‘With Sicura Litho Pack Eco we deliver once again on our commitment to drive the change towards a Circular Economy by supporting the development of circular packaging with innovative and eco-friendly inks and coatings,’ said Mustafa Guler, vice president BU Sheetfed EMEA at Siegwerk. ‘With 40 percent bio-renewable content, it is not only comparable to certain conventional oil-based inks, but it also represents a new eco-friendly alternative for UV offset printing. Its formulation is particularly designed for recycling and therefore for not impacting the recyclability of paper and board substrates at all.’ 

Test runs regarding the series’ deinkability are currently under way to further determine its potential to also improve recycling of UV-printed paper and board packaging.

According to Siegwerk, increasing the bio-renewable content in inks can support the de-fossilization when sensibly used. Bio-renewable materials also come with challenges for example regarding sustainable sourcing and the preferred end-life concept of packaging.

‘We generally support the ambitions to increase bio-renewable content where possible and in line with the three levers of a circular economy – reduce, reuse and recycle,’ added Guler. ‘Not all raw materials can be replaced by bio-renewable one’s going forward. However, increasing the amount of these materials in our solutions plays a significant role in meeting our goals, and close a gap where there are inevitable material losses and leakage.’
