Food packaging between product protection and the circular economy
In the food sector, the right packaging determines shelf life, product safety and transportability - and helps to reduce food losses.

In order to increase the currently limited use of bioplastics and biocomposites in long-lasting products, sufficient information must be generated on their long-term durability and the factors influencing it. Scientists from the University of Kassel, the University of Stuttgart and the Fraunhofer Institute for Applied Polymer Research, together with Altair Engineering GmbH, have been working on the investigations since October 2021.
In addition, over 50 industrial partners are working on the project and contributing their expertise. The results obtained are to be incorporated into a database established in the plastics processing industryto make them easily accessible to companies. The BeBio2 research network is funded by the Federal Ministry of Food and Agriculture (BMEL) about the Agency for Renewable Resources (FNR) promoted.
Improving the data situation
To date, limited knowledge and information that is difficult to access have hampered the use of bioplastics. The hurdles are particularly high for SMEs. These findings are based on the BioResist study already conducted The study was based on a literature review and a survey of company representatives and technical experts on the durability of bioplastics and biocomposites.
Based on this study, the data on the durability of numerous bioplastics and biocomposites is to be analysed. significantly improved and made publicly accessible will be realised. The aim is to promote the increased use of bio-based materials. The close cooperation between the research institutions and numerous companies ensures the practical relevance of the results for the companies and direct utilisation is realised.
Identify influences, develop scenarios
The investigations are aimed at the resistance to numerous factors, such as media, temperature and biodegradation. It is important to identify the influencing factors depending on the industry and to develop different ageing scenarios. Accordingly, components in the engine compartment are subject to different influences (greases, oils, etc.) than toys (cleaning agents, etc.) or electrical items (temperature, etc.).
The durability is also influenced by processing parameters and structural properties. Different products from a wide range of industries are therefore to be testedto optimise suitable bioplastics so that they can be used in the corresponding product sectors.
The research network is carrying out a total of twelve sub-projects at the three participating research institutions. Altair Engineering GmbH is also involved in the creation of the database. The close cooperation of all sub-projects enables synergy effects - This is the only way to achieve the goal of advancing the use of bio-based materials.
