Barrier Barrier… but

Barrier Barrier… but also bio-based and thermoformable! Like its precursor Wheylayer ® , the barrier biomaterial featured in a past issue of this publication [1], ThermoWhey is a barrier coating based on whey protein. As a by-product of cheese manufacturing, whey is available in abundance, which means there is no direct competition with food resources. Wheylayer [2] offers an excellent barrier against oxygen. Although it has the potential to replace current synthetic barrier layers, such as ethylene vinyl alcohol copolymers – EVOH – used in food packaging, it is mainly aimed at plastic laminates (e. g. pouches, tubes, lids, etc.). While it is able to be thermoformed, as demonstrated by the production of blisters, this is limited to a small stretch ratio unless performed right after the coating application. Indeed, upon storage, the flexibility and thermoformability of the coating decreases due to the formation of different new intermolecular interactions in the protein network [3]. Thermoforming is one of the dominant and growing technologies in the packaging market. However, the limited thermoformability of Wheylayer may well have stood in the way of certain applications, such as trays, for which there is an actual need. Indeed, despite having existed on the market for years, bio-based trays do not meet the barrier properties required for sensitive food products (e.g. for products packed in modified atmosphere – MAP). Therefore, selected partners from Spain (IRIS, Serviplast) and Germany (Fraunhofer IVV, MLANG), who had participated in the previous project, decided to work together with a tooling company (GEBA) to improve the long term thermoformability of whey protein-coated packaging, with an ultimate goal the production of jars, cups, etc. To this end, during the first year of the Thermowhey project [4], the researchers performed different modifications of the whey proteins and adjusted the coating formulation to obtain materials with a more thermoplastic-like behavior, i. e. displaying both stable processability and barrier properties versus storage time. After this had been successfully carried out, different deep trays were produced under optimized processing conditions from polyethylene terephthalate (PET) and polystyrene (PS) to which the Thermowhey coating was applied. Further tests will be performed on bioplastic substrates. Over the next year, the production of the material will be industrialized by the participating SMEs and resulting packaging will also be validated in contact with selected food products. The ThermoWhey project is expected to have a very positive impact on the environment, as it solves multiple challenges: finding a new commercial use for a cheese byproduct that is currently discarded, replacing petroleumbased plastics with natural biopolymers that allow packaging recycling or composting while safeguarding their performance. The author wishes to acknowledge the European Community‘s Seventh Framework Programme for Research, technological development and demonstration for co-funding the Thermowhey project under the Manunet programme through the Catalan Agency ACCIÓ (grant agreement RDNET 13-3-005) and the Federal Ministry of Education and Research of Germany (managed by the KIT Project Management Agency Karlsruhe).

Authors are experts from the nova-Institute in cooperation with ten renowned international experts. Bio-based polymers: Evolution of worldwide production capacities from 2011 to 2020 million t/a 20 15 actual data forecast Constant Growth of Bio-based Polymers is expected: Production capacity will triple from 5.1 million tonnes in 2013 to 17 million tonnes in 2020, representing a 2% share of polymer production in 2013 and 4% in 2020. Bio-based drop-in PET and the new polymers PLA and PHA show the fastest rates of market growth. The biobased polymer turnover was about € 10 billion worldwide in 2013. Europe looses considerable shares in total production to Asia.
