New multipack yogurt cups made from PP

Project Snap – PS to PP

Greiner Packaging has substituted yogurt multipacks created from polystyrene (PS) with polypropylene (PP). And ‘Project Snap’ name has now, fortunately, recreated the ‘snap,’ which customers love.

Yogurt multipacks have regularly been pack in polystyrene (PS), but there is no PolyStyrene recycling curbside program in the United Kingdom. And supermarkets have concentrated on eliminating all PS products. 

Journey Started – seek an alternative.

So, UK people and companies seeking to fulfill a sustainable alternative, in February 2018, Greiner Packaging’s Dungannon factory started trials utilizing polypropylene (PP) and led the UK to recreate a practical multipack in PolyPropylene.

One of the benefits of PS was its capability to perform an effective ‘break’ which has initially been difficult to achieve with PP. Leading UK retailer Tesco was one of the first clients to move from PS multi-packs to PP multi-packs, but users were dissatisfied that packs made from the new material did not ‘snap’ in a similar way as the previous PS packs.

In July 2020, Greiner Packaging launched ‘Project Snap’ to evolve and develop PP multipack breakability. By October 2020, Completed the first successful filling trials with Polyproplene multipack and the new, enhanced yogurt 100g 4-packs are now on the retail shelf.

Multipack PP cups development from PS has taken significant investment but has been completed faster than initially foreseen, with ‘Project Snap’ presenting the final part of the story.

Combined Efforts

Achieving with international thermoforming specialist Kiefel, thermoform machine maker Illig, and filling and sealing specialists Trepko and Clondalkin in February 2018.

Simple Pack with Multi-possibilities 

Greiner Packaging started generating a 4-pack PolyProplylene multipack that could be separated. Production tooling was supported, and by September 2018, filling and sealing trials were underway at a UK dairy company. By August 2019, all production trials were finished, and by the end of 2019, the new PP multipacks were started in the retail sector. Thanks to ‘Project Snap,’ the new, improved multipacks are now in retail.

Future Approach 

Greiner Packaging is currently heavily included in using recycled materials such as r-PET, r-PS, and r-PP for the food industry.

It is utilized more significant quantities of recycled material to manufacture its plastic products in the future. A holistic strategy, together with the research for different material alternatives, should lead to quick results, irrespective of whether an issue compares to new material-specific process innovations or appropriate food approvals.
