Adherence to innovation, sustainability and the environment has prompted the Xumuxua brand to commit itself to the use of more sustainable packaging. Its R&D team, together with the Biomat research group of the UPV/EHU-University of the Basque Country, has assessed various materials and packaging types to select the most suitable, while safeguarding food safety, product freshness and quality. In addition, innovation in packaging design involving the modification of moulds used to seal trays has enabled costs to be optimised. This collaboration has enabled Yon Mikel Janariak, marketed under the Xumuxua brand, to present its line of fifth-range products in biodegradable packaging.
