INNOVATION | RIGID PACKAGING


Right: Jokey has an agree- ment with Repsol and Spanish organic dairy company Cantero de Letur for the use of recycled plastic packing for its cheese products


out the analysis following the RecyClass Recyclabil- ity Evaluation Protocol for PP containers. The results show that a concentration of up to 6% of EVOH (with respect to overall packaging weight) tied with PP-g-MAH will not have a negative impact on the rigid PP and, therefore, is fully compatible with the respective stream. Additionally, the same structure with concentrations higher than 6% of EVOH was found to have limited recycling compatibility. Both conclusions are applicable to all types of PP rigid packaging, which includes not only bottles and sheets that were tested but also tubes, pots and trays. The recycled material coming from this packaging can be used in high-end applications including bottles and sheets. RecyClass recommends that the EVOH-barrier layer is compatibilised with a minimal amount of tie layer, with a ratio below two of EVOH to tie layer. The recommendations are not to be universally applied to other types of tie layers, as their compatibility must be further tested. The results are being used to update the


RecyClass Design for Recycling Guidelines for PP Natural and Coloured Containers, as well as the RecyClass Online Tool. RecyClass says that these findings are in line with the previous testing done on EVOH in HDPE containers released in 2020. They contribute to increasing the knowledge about the functional barriers and their impact on the recyclability of plastic packaging. A number of rigid packaging manufacturers continue to develop products containing increas- ing amounts of recycled plastics. For example,

from German packaging company Jokey Group for its clay plaster,


where the buckets consist of at least 50% post- consumer recyclates (PCR). Jokey manufactures containers from PCR obtained from household collections and the proportion of used plastic can be up to 100%. Jokey has had packaging made from recycled plastics in its range since the early 1990s. It says paints, construction materials, chemicals and other non-food products are packaged just as safely and reliably in it as in virgin plastics. It can be attractively designed and returned 100% to the recycling cycle. By using this packaging, Jokey says that its customers are making an active contribution to protecting resources and strengthening the circular economy. Environmentally conscious end consumers can easily identify the recycled packag- ing at the point of sale by its grey colour resulting from the production process and can specifically opt for sustainable solutions when making their purchasing decisions.
