Sidel designs PET bottles for Yili’s Changyi brand yoghurt drinks in China

Switzerland-based Sidel has developed a new PET bottle for Yili liquid milk division’s new Changyi brand.

Chinese dairy producer Yili Group has launched its new range of Changyi yoghurt drinks in the new Sidel PET bottles in the country.

Sidel packaging design and development manager Steven Xie said: "Our packaging experts delivered a wide selection of creative proposals, producing various conceptual bottles based on different design directions, to give the client several alternatives to differentiate its yoghurt brand from the competition.”

Earlier, Yili's liquid milk product department selected Sidel to design new PET bottle for its new range drinking yoghurt.

Within two weeks, Sidel packaging team put together a first design proposal.

The Yili's marketing department then assessed the various designs and shortlisted four preferred choices following which Sidel made small adjustments to the different designs including shape of the bottle's base.

The base has been designed to improve shelf-life and rigidity in order to avoid deformation during transportation.

Xie added: "Leveraging our global expertise in PET packaging design and production, we ran multiple tests to assess the performance of the bottle and finally we found the best solution.”

Sidel said it completed the bottle design in three months. New moulds were also created for the two Yili production lines dedicated to the new yoghurt range.

Yili Group processes and manufactures milk products, including ice cream, powdered milk, sterilised milk and fresh milk, among others.
