Food packaging made from bio-based plastics is seen as an alternative to traditional plastic packaging, but has so far only been insufficiently adapted to their high technical requirements. By funding four research projects, the Federal Ministry of Food and Agriculture (BMEL) aims to open up new areas of application for bio-based plastics in food packaging.<\/strong><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

The food industry in particular is calling for alternatives to conventional packaging. Bio-based plastics based on renewable raw materials are repeatedly cited as a solution. As food packaging, however, they still have a number of technical and functional weaknesses.<\/p><\/div><\/div><\/div>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

With the call for funding \"Bio-based plastic packaging for food\", the BMEL has invited research and industry to develop ideas for improving the potential uses of bio-based plastics in the food industry. Four research approaches have emerged from this call and are now being funded by the BMEL via its project management organisation Fachagentur Nachwachsende Rohstoffe e. V. (FNR).<\/p>

What they all have in common is that the packaging should have as high a bio-based content as possible and that it must be recyclable. In addition, all four approaches deal with demanding areas of application in terms of packaging technology.<\/p><\/div><\/div><\/div>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Sensitive foods, such as sausage, cheese, etc., are often packaged in a modified atmosphere (MAP). The bio-based plastic polylactide (PLA) is not always suitable for this process, mainly due to its high water vapour permeability.<\/p>
