Polymer layers in packaging films to be replaced by a new bio-based material

April 21/2011

(Ceepackaging) -- Polymer layers in packaging films may soon be able to be replaced by a new bio-based material made from whey protein. This material has excellent techno-functional properties. At the interpack fair from 12 to 18 May 2011 in Dusseldorf a packaging film having a barrier layer made of whey protein will be shown. This material was developed as part of the Wheylayer EU project. Large quantities of whey are produced during cheese manufacture and whey also contains antimicrobial substances. The multilayer film was manufactured using a roll-to-roll method. This processing method is a key precondition for fulfilling commercial criteria. The products and processes that have thus far been developed on a laboratory and pilot plant scale will be transferred to an industrial scale this year, meaning that the new whey layer material will soon be able to be used in the packaging sector.
