New UV offset ink series with high bio renewable content from Siegwerk

Ink Solutions

Siegwerk is now offering a new sustainable UV offset ink series for non food paper and board applications: Sicura Litho Pack Eco. The new product range is formulated with a high bio renewable content, providing an environmentally friendly alternative to standard UV inks.

The formulation of the new Sicura Litho Pack Eco series consists of more than 40% 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 odour ink series and especially designed for all kinds of paper and board substrates.

The series shows excellent ink performance and a high colour strength. Next to high dot gain sharpness and an 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 colour process inks according to ISO, Pantone colours, base inks, special colorus 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% 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 underway 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 defossilisation when sensibly used. Bio renewable materials also come with challenges for example regarding sustainable sourcing and the preferred end life concept of packaging.

That is why the company only works on bio renewable inks and coatings that support a circular end life solution like recycling. ‘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 Mustafa. ‘Not all raw materials can be replaced by bio renewable ones 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.’
