Packaging

The packaging sector is subject to enormous cost pressure: packaging material must not usually cost much, but is very important for the quality and shelf life of the end product.

In addition, the demand for packaging materials is constantly increasing. In contrast, the amount of materials based on fossil raw materials must be reduced in order to contribute to a sustainable future. The proportion of renewable, bio-based materials for packaging products must increase in order to avoid environmental pollution, e.g. through microplastics.

Technologies for vacuum coating and surface modification with electrons from the Fraunhofer FEP are ideally suited to this task due to their high productivity and the very good surface properties that can be achieved.

Based on our technological expertise, we offer in particular the functionalization of bio-based and biodegradable films as well as monomaterials, for example for permeation barriers to extend the shelf life of the product. We also use electron beam technology to modify the surface of plastics or to cure printing inks or lacquer-based functional layers.

We support you with the development of highly productive technologies and processes for the finishing of your packaging!

Improved surface and material properties of bio-based and biodegradable films

Functionalization of bio-based and biodegradable films and monomaterials

  • Barrier layers (H2O, O2)
  • Anti-adhesive layers
  • Layers approved for food contact
  • Hydrophobic/hydrophilic layers
  • Lipophobic/lipophilic layers

Transparent barrier layers for packaging films

The Fraunhofer FEP offers innovative technologies for coating polymer films with oxide layers that produce high-performance, transparent barrier layers.

Technical features and advantages

  • Effective barrier against oxygen and moisture, protects food and extends its shelf life
  • Inorganic barrier layers compatible with mechanical and chemical recycling
  • Ideal for mono-material packaging
  • Transparent silicon oxide or aluminum oxide layers ideal for food packaging with a view of the product
  • High coating rate for cost-efficient process optimized for industrial production of mass products such as packaging materials
  • Industrially proven and commercially available technology
  • Vacuum-based roll-to-roll coating process for coating several thousand square meters of film per hour
  • Suitable for biodegradable films such as polylactic acid (PLA) as well as common polymers such as PET and polypropylene (PP) 

 

 

Curing of printing inks and lacquers with low-energy electrons

The Fraunhofer FEP uses low-energy electron beams to cure printing inks and coatings quickly and in an environmentally friendly way, resulting in high-quality surfaces. We offer processes for coating application and curing in a vacuum as well as in an atmosphere.

Technical features and advantages

  • Fast curing: Curing in fractions of a second for high production speeds
  • Low energy input: Minimal thermal load, ideal for temperature-sensitive materials
  • Solvent-free process: Environmentally friendly technology with no volatile organic compounds (VOCs)
  • High surface quality: Creates scratch-resistant, chemical-resistant and smooth surfaces
  • Wide range of applications: Can be used for packaging, decorative films and printed products

Our offer

Fraunhofer FEP offers customized roll-to-roll surface technologies for the development of sustainable, flexible packaging made from biodegradable or bio-based polymer films.

These technologies make it possible to adapt the films specifically to the requirements of modern packaging applications. In addition, high-performance surface technologies and development tools are available to efficiently realize innovative and environmentally friendly packaging solutions. We also offer:

  • Functionalization and process development
  • Development of coatings from defined individual layers to multi-layer stacks
  • Adaptation of the coatings to the surface roughness, adhesive behaviour, etc. of the substrates
  • Optimization of the physical properties of polymers for processability in roll-to-roll coating systems (elasticity, slip)
  • Process development and associated key technological components for the processability of polymer substrates
  • Sample coatings of your substrates
