Siegwerk, a global provider of printing inks and coatings for packaging applications and labels, has announced the introduction of the Sicura Litho Pack – a new UV offset ink series for the EMEA market for non-food packaging applications made of paper, board and plastic substrates.

The new low odor product range follows the latest Siegwerk Exclusion Policy guidelines – based on the EuPIA Exclusion Policy – and is formulated without CMR category 1 substances such as Benzophenone. CMR substances are those that are carcinogenic, mutagenic or toxic to reproduction In addition, the new series is free of TMPTA (trimethylolpropane triacrylate) and PFAS/PTFE. 

With the launch of our new Sicura Litho Pack series, we offer customers in the EMEA region the next generation of UV offset inks and varnishes especially formulated for the use on cardboard and various synthetic substrates,” says Jerome Fumex, EMEA Customer Service & Product manager of Business Unit Sheetfed at Siegwerk

From coated and metallized paper and board to aluminum and plastics, the new low odor UV series has a great versatility of use with outstanding adhesion properties suitable for the complex substrates of the luxury industry. 

Besides, the Sicura Litho Pack has an excellent deinkability according to the Ingede 11 method, and thus contributes to an easier recycling of UV-printed packaging,” adds Fumex. The Sicura Litho Pack offers the same good deinking properties as the Sicura Litho Pack ECO, a recently launched sustainable UV offset ink series for non-food paper and board applications made of more than 40% of renewable and vegetable-based components.

First users confirm an excellent press run stability and a high color strength of the Sicura  Litho Pack. Next to a very good flowability and high ink transfer, Siegwerk’s new UV offset range showed a very stable ink/water balance even during long runs as well as a good film flexibility for post-processing. The series requires low damp settings and impresses with a very good and sharp print quality. The product range contains standard process colors according to ISO as well as a wide color set for mixing systems. In addition, the prints can be overprinted with UV varnishes or lamination, for example with the company’s newly developed range of TMPTA-free flexo and offset OPVs, which is also available now.

Due to increasing safety concerns of brand owners, leading to the strict exclusion of certain substances and raw materials used for their products and packaging, there is a need to also adjust related ink and coating formulations. With its new Sicura Litho Pack series, Siegwerk offers its customers an enhanced UV solution based on state-of-the-art formulation technology, addressing the latest guidelines of brand owners worldwide. 

The plan is that the new series will completely replace our previous UV offset series Sicura Plast SP by end of 2023 latest,” says Fumex. “Therefore, we paid attention to keep the exact same colorimetry on mixing bases to avoid any reformulation work for the existing recipes of our customers.” For all necessary process setups and calibrations, the company’s technical experts are available as usual to support a smooth changeover to the latest generation of Siegwerk UV inks.

The impact, resilience, and growth of responsible packaging in a wide region are daily chronicled by Packaging South Asia.

A multi-channel B2B publication and digital platform such as Packaging South Asia is always aware of the prospect of new beginnings and renewal. Its 16-year-old print monthly, based in New Delhi, India has demonstrated its commitment to progress and growth. The Indian and Asian packaging industries have shown resilience in the face of ongoing challenges over the past three years.

As we present our publishing plan for 2023, India’s real GDP growth for the financial year ending 31 March 2023 will reach 6.3%. Packaging industry growth has exceeded GDP growth even when allowing for inflation in the past three years.

The capacity for flexible film manufacturing in India increased by 33% over the past three years. With orders in place, we expect another 33% capacity addition from 2023 to 2025. Capacities in monocartons, corrugation, aseptic liquid packaging, and labels have grown similarly. The numbers are positive for most of the economies in the region – our platform increasingly reaches and influences these.

Even given the disruptions of supply chains, raw material prices, and the challenge of responsible and sustainable packaging, packaging in all its creative forms and purposes has significant headroom to grow in India and Asia. Our context and coverage engulf the entire packaging supply chain – from concept to shelf and further – to waste collection and recycling. We target brand owners, product managers, raw material suppliers, packaging designers and converters, and recyclers.
