Saralon GmbH – a provider of inks for sustainable paperelectronics

Printed Zn-MnO2 battery on paper developed by Saralon in IMPETUS

Saralon’s technology to simplify printed electronics

Sustainability has become a necessity in the electronic industry. Saralon GmbH (Chemnitz, Germany) introduces its latest inks for sustainable paper electronics. Keeping the need of color printing companies in mind, Saralon has simplified the complete production process of printed electronics, which is called InkTech. InkTech is a combination of inks and production technologies for printed electronics. Apart from selling inks, Saralon provides complete production know-how for ready-to-use applications.

Printing process

In traditional color printing, multiple color layers are printed with almost similar thicknesses. But in printed electronics, different layers are printed with different thicknesses, ranging from few nanometers to hundreds of micrometers. Saralon has solved and simplified all these issues to transfer the know-hows to printing companies through an onsite training.

Integration process

In order to create an application based on printed electronics, the integration of graphics printed objects with electronics must be done in a cost-effective way. Saralon, with its long expertise in the field of integration techniques provides full support to printing companies to develop ready-to-use applications.

Sustainable Electronics

Electronics produced by printing machines and by using Saralon’s InkTech are sustainable. The sustainability features of Saralon’s InkTech are explained below.

  • No toxic chemicals

  • Easily recyclable

  • Reduced carbon emission

  • Low waste during production

Role in IMPETUS project

Batteries are important components of electronic devices. Commercially available batteries are either in metal casing or in plastic pouch. Printed batteries available on the market are also packaged in plastic pouches. In order to convert printed batteries into a more sustainable product, plastic pouches must be replaced by a biodegradable material such as paper. Within the IMPETUS project, Saralon is developing inks and printing processes for Zinc-Manganese dioxide batteries that can be easily printed on paper. These batteries can be screen-printed by using only seven inks on a suitable barrier paper. The battery shown in the picture was produced on a barrier paper provided by the project partner Felix Schoeller Holding GmbH & Co. KG. The advantage of Saralon’s battery inks is that all layers of the battery can be printed. Complicated steps of paper placement as separator or injection of electrolyte are not required during the battery production.
