Silphie packaging for Lidl and Kaufland

2021-11-12 –


Lidl and Kaufland are promoting the use of innovative packaging made with locally grown silphie plant fibre. PreZero, the environmental division of Schwarz Group, has spearheaded a sustainable packaging solution developed in partnership with its OutNature brand and packaging expert STI Group.

Through a development partnership with OutNature, STI Group`s in-house materials lab has been exploring the technical properties of silphie material since late 2020. Pioneering tests have examined every facet of its production performance, from printability and varnishability to laminating and die-cutting. Silphie material has proven itself and can now be used in cardboard or corrugated board format for making packaging and displays.

Silphie material is already suitable for direct food contact, while further research into coatings could enhance its barrier properties against water and fats. Both Lidl and Kaufland are now phasing in the innovative solution for fruits and vegetables – starting with cress.

Locally sourced renewable raw materials

This tall flowering plant not only provides bioenergy but is also a source of fibres for paper production. Thanks to the downstream production of bioenergy and the plant’s soil-improving properties, silphie is climate-positive.
