Greiner Packaging has announced the launching of a new self-separating K3 r100 cup packaging solution in collaboration with Swiss retailer Lidl Schweiz and dairy products manufacturer Molkerei Forster.

The new packaging has been launched for Lidl’s own brand Milbona.

It will be available as 500g tubs for Milbona natural yoghurt products with 1.5% and 3.5% fat content and will be sold across all Lidl branches.

The move comes as Molkerei and Lidl were planning to introduce more sustainable packaging alternatives to replace the traditionally used cardboard-plastic combinations for their dairy products offering.

Greiner said it first manufactured the K3 packaging solution at its site in Diepoldsau, Switzerland, around four decades ago.

The three companies worked in close collaboration to develop K3 r100 after completing a series of filling tests for the packaging at Molkerei’s site.

Greiner Switzerland sales director Antonios Kampouris said: “Before we brought the cup to market, we perfected it in numerous filling tests – including on Molkerei Forster’s systems.”

The jointly developed packaging enables cardboard and plastic to separate from each other, without the requirement of human intervention.

Molkerei founder Markus Forster said: “We have set ourselves the goal of focusing on sustainability. This begins with the raw materials used and continues through our production processes to product packaging and beyond.

“With K3 r100 we are taking another important step towards a sustainable future.”

The latest innovation is hoped to lay the foundation for future collection systems in Switzerland.

K3 r100 will ensure that even if a person has not separated the cardboard wrap from a cup while disposing, the two parts will still be able to separate from each other by leveraging mechanical pressure.

As a result, plastic cups and cardboard wraps can easily be identified and assigned to their respective recycling streams.

Lidl Schweiz CCO Andreas Zufelde said: “We are pleased to be taking another joint step forward in the packaging sector. By introducing innovative yoghurt packaging, we are once again underlining our commitment to recycling sustainability and design.”
