At the end of the 1980s, we developed a process for manufacturing embossed polypropylene films (PP) – a patented process allowing the film, including embossing, to be extruded directly out of the melting mass. With a host of benefits for the application field involved.

If required, the PP films can be extruded 30% more strongly at the edges and in the middle than at others points. As such, the specific reinforcement of the films leads to much greater stability of the upper and lower edges of the fills. Not only with a 300mm block but also with a 600mm block height.

And there is more: The optimized film strength distribution in combination with our developed PP compound ensures an exceptionally high resistance to erosion that is caused by the constant impact of water.

For over 25 years we have been using this patented process in the manufacturing of our PVC foils as well.

The result: Our particularly resistent, solid PP and PVC fills
PLASdek® and BIOdek® fills are made out of PP and hard PVC. One of the benefits of this process is that its energy consumption is only one third of that of traditional methods. During traditional processes flat film is produced first and deformed in a second step. Thus, the request of the industry for barely flammable and self-extinguishing materials is fulfilled.

Client and application specific materials
We produce – together with our clients and partners, too – new PP and PVC compounds that can meet specific requirements. Examples are the anti legionella SANIPACKING mixture and flame protection formulations which match a variety of requirements and tests. In case of exposure of the fills to chemicals, especially oxidative mediums, or if a high thermal resistance is required, we also offer fills made out of PVDF. You have a special request as well?

Perfect Connections – Welding instead of glueing
The wish to produce environmental-friendly inspired us to weld instead of glueing the foils. The welding process that we developed allows dispersing the use of adhesives altogether. No solvent adhesives- thus no solvent emissions. This is more than just a contribution to the protection of the environment. Dispersing with adhesives, chemical threats through which the adhesive could dissolve are also eliminated.

Instead, the foils are welded firmly and systematically. Depending on the type of fill up to 20,000 welding spots per cubic meter (!) guarantee an outstanding connection of the foils. These are extremely resistant with up to 35 tons/m2. The stability of this connection technology was also confirmed by long-term tests by accredited test laboratories such as TÜV (German authorized inspection agency).
Another benefit: The process can be implemented on the construction site. This saves costs to a high degree because transporting the foils needs only 10% of the volume compared to the fills.
