Bio-based multilayer barrier films: Four key players in the bioplastics industry, Eurotech Extrusion Machinery, NatureWorks, Nippon Gohsei, and Sukano, have successfully processed a multilayer transparent bio-based barrier film, offering a potential replacement for conventional fossil fuel-based structures for dry food packaging. The film consists of an inner layer made from NatureWorks’ Ingeo PLA as well as tie and barrier layers using special polymers from Nippon Gohsei. The film is processed at Europeach using a K5A 5 layer blow film lab machine. The use of Sukano’s PLA-based masterbatches offers increased melt strength, and therefore better processability, good transparency and better adhesion during sealing. As an additional benefit, each material used in the film has either been tested and certified or assessed to be biodegradable and industrially compostable according to European norm EN 13432.
