DG press offers mono-material packaging printing with one-pass

DG press, a manufacturer of hybrid web offset presses, has developed a printing and coating platform for the food packaging industry, designed to upgrade the properties of mono-material packaging by applying functional coatings while simultaneously applying printed graphics and varnish in one pass.

According to the company, the integration of mono-materials with functional coatings has emerged as one of the important innovation directions, providing required barrier properties and, at the same time, easy deinking performance, leading to improved recyclability and a higher purity recyclate. For best efficiency, this approach requires a flexible and versatile printing platform capable of combining and applying various technologies in one pass.

With the DG-Auxo hybrid web offset press series, DG press has developed a print production platform that provides technologies for handling these new and inventive material combinations.

As per the company, when utilizing energy-curable ink, the DG-Auxo press series contributes to the elimination of solvent-based inks, resulting in a reduction in carbon footprint.

The modular design of the DG-Auxo allows for combining multiple print technologies in a press configuration that facilitates a broad range of new and future packaging applications.

In a recent case study, DG press, together with its project partner Siegwerk, produced mono-PE material coffee packaging with an enhanced oxygen barrier.

Siegwerk’s oxygen barrier coating, Cirkit Oxybar BC 1582, was applied onto a mono-PE film structure, achieving a reduction of the oxygen transmission rate (OTR) that surpasses the OTR of some similar structures with traditional barrier layers.

Besides enhancing the oxygen barrier properties of the mono-PE film, the barrier coating also provides superior deinking performance, making it an even more attractive alternative to traditional materials.

‘With the development of the DG-Auxo press, DG press made a statement of commitment to sustainable and innovative packaging production. Its seamless combination of multiple printing and coating technologies allow the printing and coating of various materials in one pass. The elimination of time and waste between the different production stages offers efficiency and flexibility, especially for customized products and for small and medium-sized job volumes,’ said the company in a statement.
