Biopolymers can be processed into films using conventional machinery – this will be demonstrated in a workshop given by the Fraunhofer Institute for Applied Polymer Research IAP in Schwarzheide on June 10, 2015. In addition, new developments that considerably expand the range of familiar applications in the field of biopolymer films will be presented. Special attention will be given to co-extruded systems of films. The workshop is directed towards film manufacturers and processors, representatives from plastics groups and associations, as well as research institutions.
Films represent an important area of the plastics industry. The range of applications is diverse, from flexible films for the packaging sector, to bags and sacks, shrink-wrap and expanding films, films for agricultural and construction applications, films for office use and office supplies, insulating films, as well as other industrial film applications.
The characteristics and behavior of various biopolymers show great potential for these markets. The most well-known is a material named polylactic acid (PLA) along with the blends and compounds produced from it, though other more recent raw materials like polybutylene succinate (PBS) have come on the scene. However, biopolymer prices are quite high and their properties do not equal those of conventional petroleum-based polymers in all areas.
“In order to be able to utilize bioplastics for production of tubular or sheet film, the materials need to possess good processing properties and product characteristics. You also have to be sure that bioplastics can be processed by machinery available on the market just as well as common petroleum-based plastics can. We are researching both these areas at Fraunhofer IAP and have some very interesting new developments. We would like to share our experience and this knowledge with the workshop participants”, explains Dr. Mathias Hahn, a biopolymer expert at IAP.
Guest speakers from Mitsubishi Chemical Performance Polymers Corp Germany (MCPP) and Wacker Chemie AG will also be reporting on their experience and developments in the area of biomaterials including processing them in production. Moreover, opportunities for support of projects promoting the employment of biopolymers in plastics processing will be presented.
Last but not least, the event will promote the exchange of information and explore potential synergies as well. A tour of the Processing Pilot Plant for Biopolymers at Fraunhofer IAP in Schwarzheide will round out the program. Those interested in employing bioplastics for the production of film or those with general questions about bioplastics and how they are processed are invited to take part in this event.
The workshop is taking place as part of the Competence Network for the Processing of Biopolymers (KNVB) joint research project funded by the German Federal Ministry of Food and Agriculture (BMEL) through project sponsor FNR (Fachagentur Nachwachsende Rohstoffe e.V., an association dedicated to renewable resources).
Fraunhofer IAP conducts research in association with the Institute for Bioplastics and Biocomposites (IfBB) of the University of Applied Sciences and Arts Hanover, the German Plastics Center (SKZ) in Würzburg, and the Department of Lightweight Structures and Polymer Technology (SLK) at Technische Universität Chemnitz.

Plants and algae use the enzyme Rubisco to fix carbon dioxide, removing it from the atmosphere and converting it into biomass. Algae have figured out a way to increase the efficiency of carbon fixation. They gather most of their Rubisco into a ball-shaped microcompartment called the pyrenoid, which they flood with a high local concentration of carbon dioxide. A team of scientists at Princeton University, the Carnegie Institution for Science, Stanford University and the Max Plank Institute of Biochemistry have unravelled the mysteries of how the pyrenoid is assembled. These insights can help to engineer crops that remove more carbon dioxide from the atmosphere while producing more food.

Our brains house extremely complex neuronal circuits, whose detailed structures are still largely unknown. This is especially true for the so-called cerebral cortex of mammals, where among other things vision, thoughts or spatial orientation are being computed. Here the rules by which nerve cells are connected to each other are only partly understood. A team of scientists around Moritz Helmstaedter at the Frankfiurt Max Planck Institute for Brain Research and Helene Schmidt (Humboldt University in Berlin) have now discovered a surprisingly precise nerve cell connectivity pattern in the part of the cerebral cortex that is responsible for orienting the individual animal or human in space.
The researchers report online in Nature (Schmidt et al., 2017. Axonal synapse sorting in medial entorhinal cortex, DOI: 10.1038/nature24005) that synapses in...

Using ultrafast flashes of laser and x-ray radiation, scientists at the Max Planck Institute of Quantum Optics (Garching, Germany) took snapshots of the briefest electron motion inside a solid material to date. The electron motion lasted only 750 billionths of the billionth of a second before it fainted, setting a new record of human capability to capture ultrafast processes inside solids!
When x-rays shine onto solid materials or large molecules, an electron is pushed away from its original place near the nucleus of the atom, leaving a hole...
For the first time, physicists have successfully imaged spiral magnetic ordering in a multiferroic material. These materials are considered highly promising candidates for future data storage media. The researchers were able to prove their findings using unique quantum sensors that were developed at Basel University and that can analyze electromagnetic fields on the nanometer scale. The results – obtained by scientists from the University of Basel’s Department of Physics, the Swiss Nanoscience Institute, the University of Montpellier and several laboratories from University Paris-Saclay – were recently published in the journal Nature.
Multiferroics are materials that simultaneously react to electric and magnetic fields. These two properties are rarely found together, and their combined...
