| Résumé : |
Within the "BarriFlex" joint project, novel nano-tailored materials with improved barrier properties against gas and water vapor were developed for packaging applications. These materials form the basis of new packaging concepts. Despite intensive research, much still remains to be done as regards diversity of materials, barrier specifications and more efficient manufacturing processes for new, inexpensive, easy-to-recycle and even renewable packaging products. |

- Nanolacquer formulation
- Manufacture of mono-material laminates for food packaging
- Atomic layer deposition and laminate structures for organic photovoltaics
- Fig. 1 : Top: the integration of platelet-shaped, impermeable nanoparticles extends the diffusion path. Bottom: scanning electron image of an adequate PVA coating without (left) and with (right) nanoparticles
- Fig. 2 : Coating of a PP film with nanolacquer containing 50 wt. % nanoparticles using the slot die technique. Right: schematic diagram of a roll-to-roll coating unit
- Fig. 3 : Oxygen permeation rate for different mono-material laminates. The left bar shows a blank sample without an active barrier layer (to show the differences between the other samples, this bar has been truncated). The industrial standard is a co-extruded high barrier film, which is commercially available. The two samples on the right show the new development within the BarriFlex project and the improvement factor achieved by integrating nanoparticles
