Siegwerk Offers New UV Offset Ink Series

Siegwerk, one of many main international suppliers of printing inks and coatings for packaging functions and labels, is now providing a brand new sustainable UV offset ink collection for non-food paper and board functions: SICURA Litho Pack ECO. The new product vary is formulated with a excessive bio-renewable content material, offering an environmentally pleasant various to plain UV inks.

The formulation of the brand new SICURA Litho Pack ECO collection consists of greater than 40% of renewable and vegetable-based elements exhibiting a 4 occasions larger share of bio-renewable content material than the typical normal UV ink. Furthermore, the collection is freed from TMPTA, Benzophenone in addition to CMR CAT. 1 and CMR Cat. 2 elements. It is a low odor ink collection and particularly designed for every kind of paper and board substrates. SICURA Litho Pack ECO is appropriate for all non-food packaging functions the place particular consideration is paid to the packaging’s environmental impression and circularity. The collection exhibits wonderful ink efficiency and a excessive coloration energy. Next to excessive dot acquire sharpness and a very good flowability, Siegwerk’s new UV offset vary affords a really secure ink/water stability even throughout lengthy runs in addition to a superb movie flexibility for post-processing. The product vary comprises 4 coloration course of inks based on ISO, Pantone colours, base inks, particular colours in addition to flexo OPV.

“With SICURA Litho Pack ECO we ship as soon as once more on our dedication to drive the change in the direction of a Circular Economy by supporting the event of round packaging with progressive and eco-friendly inks and coatings,” says Mustafa Guler, Vice President BU Sheetfed EMEA at Siegwerk. “With 40% bio-renewable content material, it’s not solely akin to sure standard oil-based inks, however it additionally represents a brand new eco-friendly various for UV offset printing. Its formulation is especially designed for recycling and subsequently for not impacting the recyclability of paper and board substrates in any respect.” Test runs concerning the collection’ deinkability are at the moment below option to additional decide its potential to additionally enhance recycling of UV-printed paper and board packaging.

According to Siegwerk, growing the bio-renewable content material in inks can help the de-fossilization when sensibly used. Bio-renewable supplies additionally include challenges for instance concerning sustainable sourcing and the popular end-life idea of packaging.

That’s why the corporate solely works on bio-renewable inks and coatings that help a round end-life answer like recycling. “We usually help the ambitions to extend bio-renewable content material the place potential and in keeping with the three levers of a Circular Economy – scale back, reuse and recycle,” provides Guler. “Not all uncooked supplies might be changed by bio-renewable one’s going ahead. However, growing the quantity of those supplies in our options performs a major function in assembly our targets, and shut a niche the place there are inevitable materials losses and leakage.”

Although, it’s extensively mentioned that bio-renewable sources personal the potential to enhance a Circular Economy as a non-fossil uncooked materials supply, there may be neither a regular definition of the time period “bio-renewable uncooked materials” nor a common consensus on methods to calculate bio-renewable content material in printing inks. That’s why Siegwerk has determined to construct up a definition of its personal, considering present scientific and political discussions and arguments. According to the corporate’s consultants particularly uncooked supplies both of vegetable, animal or microbial origin that underwent materials utilization for the manufacturing of chemical compounds, fundamental supplies and different bio-based merchandise are of curiosity for use in ink formulations. Water or supplies embedded in geological formations are in flip explicitly not thought-about as being bio-renewable. “When calculating the bio-renewable content material of our inks we concentrate on the precise share of uncooked supplies with bio-renewable origin which are current within the respective ink formulation, taking all constituents into consideration,” explains Alina Marm, Head of Global Sustainability and Circular Economy at Siegwerk. “Thereby, our calculation refers back to the sum of all elements current in a uncooked materials, additionally bearing in mind substances and solvents – besides water – which are excluded within the strategies generally used to this point, akin to ASTM D6866, EN 16640 and NAPIM.”

Transparency performs a key function in creating sustainable and eco-friendly packaging options, that’s why Siegwerk offers detailed knowledge concerning the bio-renewable content material of every of its formulations. To make the data much more related for its clients, the corporate differentiates between wet-ink and dried-ink content material when calculating the bio-renewable content material of its inks. The wet-ink worth considers all ink elements and signifies the bio-renewable content material of the ink product as such. In flip, the dried-ink worth solely considers the strong content material with out solvents and different risky elements that evaporate throughout drying. This signifies the bio-renewable content material of the ink on the ultimate print product and is subsequently particularly related for converters and finish customers. To be capable of calculate the bio-renewable content material for all its formulations, Siegwerk collected and analyzed the bio-renewable share of every uncooked materials strictly contemplating the molecular degree to have the ability to differentiate between bio-renewable and fossil elements. Today this data requirement can also be a part of the corporate’s complete Raw Material Introduction Process enabling a steady overview of all used uncooked supplies and their corresponding bio-renewable shares.

Sustainability means progress to Siegwerk. That’s why assessing methods of enhancing the ecological footprint of its inks with no lack of efficiency is likely one of the firm’s key R&D targets since many years. Here, the corporate strongly believes in the advantages of a Circular Economy and focuses its improvement efforts on inks and coatings that concretely improve the efficiency and recyclability of packaging and thereby enabling the design of round packaging options. Further extending the corporate’s portfolio of sustainable and eco-friendly product options will concretely help the renewability and additional improve the recyclability of packaging.
