Recyclable packaging - optimized by shelf-life simulation

Shelf-life simulation for developing optimal packaging and rapid shelf-life prediction

We perform software-based shelf-life analysis in order to predict how long a given product can be kept in specific packaging. The constantly updated databases and mathematical models which the software uses for the predictions means that time-consuming and complex storage tests no longer have to be carried out. Depending on the requirements of the product we perform shelf-life simulations covering a range of packaging and temperature scenarios. We quickly determine what barriers are required to maximize the shelf-life and whether, for example, the use of an active packaging system is worthwhile. You receive evaluated results and comprehensive advice on the optimal packaging for your product, regardless of whether that be food, pharmaceuticals, cosmetic goods, or a technical product.

Recovery of plastics from waste of electrical and electronic equipment

Workshop on 6 June 2018:
Recycling and Reuse of Polymers from WEEE

This workshop will be held in English and covers the recycling of plastics from WEEE (Waste Electrical and Electronic Equipment). Learn about the latest developments and the implementation of cost-effective recycling technologies. These technologies allow high-purity, commercial recyclates to be produced at favorable cost that are equivalent in quality to virgin plastics. Some of these recyclates are produced from waste plastics that even contain hazardous materials.

The workshop will take place at the Fraunhofer IVV as part of the European Union's Horizon 2020 research and innovation programme (research project no. 641747 CloseWEEE). The workshop is free and we hereby cordially invite you to attend. After the workshop there will be the opportunity to tour our laboratory and pilot plant facilities.

Analysis of odor in granulates

Characterization and optimization of odors in HDPE recyclates

Recyclates produced from post-consumer plastic packaging waste must have no off-odors if they are to be used as secondary raw materials for the manufacture of high-quality consumer products. Under the guidance of Prof. Andrea Büttner in the Sensory Analytics Department, odors in post-consumer plastic packaging waste are being analyzed. Compounds having great structural diversity and different odors have been identified. HDPE (high density polyethylene), which is used in large quantities for packaging body care products and detergents, is currently being analyzed in detail. The trained sensory panel of the Fraunhofer IVV has evaluated odors in HDPE waste, regranulates, and virgin HDPE granulates. The odors have been analyzed using analytical-olfactory methods in order to identify possible formation pathways and sources of the odorants.

The results have been published in the Journal of Cleaner Production, Elsevier Ed. These fundamental studies are the basis for developing targeted optimization and avoidance strategies for off-odors in recyclates. The next step is to test adapted recycling methods for their ability to minimize odors.

Investigation to optimize the production process

Chocolate technology at the Freisinger Tage seminar on 27/28 June 2018

The latest results and projects in the area of chocolate technology will be presented at the upcoming Freisinger Tage seminar, an event being organized by the Fraunhofer IVV in collaboration with the Industrievereinigung für Lebensmitteltechnologie und Verpackung e.V. (IVLV). The event will take place on 27/28 June 2018. The particular focus of this year's seminar is on spices in chocolate. Here the microbial load and homogeneous distribution in the chocolate also play a role. Other key aspects are the processing of hazelnuts in the manufacturing process and the effect of the chocolate recipe and processing on bloom formation and flavor release. The new Confectionery Machinery work group led by the Fraunhofer IVV Dresden will present their first projects.

Simulation of forces on the sealing seam in the drop test using the example of peelable trays

New project started on the effective transport of peelable packaging

In April 2018 Frauhofer IVV Dresden, working together with the Industrievereinigung für Lebensmittelindustrie und Verpackung e.V. (IVLV), started a project entitled "Effective transport of peelable packaging". The project is investigating how secure a sealing seam on peelable packaging must be to reliably withstand transport, handling, and storage processes en route from the manufacturer to the consumer and what variables there are for minimizing the forces on the sealing seams.

An initial research project funded by the IVLV demonstrated that even small or average forces can damage the sealing seams of peelable packaging. In the first project parameters such as the sealing seam geometry and packaging geometry will be studied. The aim is to develop a calculation tool for the development of force-optimized and hence material-optimized peelable packaging.

Companies interested in participating in the supervisory project committee are welcome to contact us.

Odor and flavor research on ARD-alpha in "Campus TALKS"

On 28 May 2018 "Campus TALKS" on ARD-alpha will be giving an insight into our work on odor identification, taste perception, and the development of sensor systems. The broadcast can be viewed at 22:15. Prof. Andrea Büttner, Deputy Director of the Fraunhofer IVV and Head of the Sensory Analytics Department, will explain the meaning of multisensory perception. Also under the spotlight will be the "Campus of the Senses" in Erlangen which is developing digital systems to simulate human sensory perception in collaboration with the Fraunhofer Institute for Integrated Circuits IIS and the Friedrich-Alexander-Universität Erlangen-Nürnberg.
