European researchers leaded by the the Spain-based Patronal de la Petita i Mitjana Empresa de Catalunya (PIMEC), have developed a biomaterial from whey protein as well as a commercially viable method of producing multifunctional films on an industrial scale. This sustainable food packaging product is a step ahead of the conventional films based on petrochemicals.

The EU-funded team of researchers, a consortium consists of experts from Germany, Spain, Ireland, Italy, Hungary and Slovenia and led by the Spain-based Patronal de la Petita i Mitjana Empresa de Catalunya (PIMEC), has developed a biomaterial from whey protein as well as a commercially viable method of producing multifunctional films on an industrial scale. This is steps ahead of the conventional films based on petrochemicals. For the WHEYLAYER project, the natural ingredients in the whey extend the shelf life of food products. An added bonus is that the whey protein layer is biodegradable.

The WHEYLAYER ('Whey protein-coated plastic films to replace expensive polymers and increase recyclability') project, which received more than €2.5 million under the 'Research for the Benefit of SMEs (small and medium-sized enterprises)', Seventh Framework Programme Capacities Work Programme of the EU, has therefore developed an innovative, sustainable food packaging product.

The results of this project will immensely benefit industry, because it will help keep their food products safe from oxygen, moisture, and chemical and biological contamination. The upshot of this development is that foods will remain fresh for as long as possible.
