Gneuss has developed the innovative MRSjump Extruder, for the process of tray-to-tray recycling,
The new MRSjump Extruder combines the high decontamination performance of the MRS degassing extruder, which has been well established over the past decades, with a viscosity boost.
The MRSjump extrusion process does not necessitate any pre- or post-treatment of the input material, such as crystallisation or pre-drying of the recycled material or an IV boost in a solid state polycondensation (SSP).
The high degassing efficiency of the MRSjump Extruder makes it possible to comply with EFSA and FDA limits without time- and cost-intensive upstream or downstream material treatment.

The simple set-up of the MRSjump direct extrusion process avoids the combination of different material treatments prior or subsequent to extrusion and resulting interface problems.
Due to the short process chain, the melt remains within a narrow, defined residence time spectrum. The thermal and mechanical stress on the material is kept low. This results in excellent mechanical and optical sheet properties.
The compact design of the MRSjump Extrusion System means that it has a small footprint and compared with other concepts available on the market, it can easily be retrofitted to an existing sheet line within the same spare requirements as an existing conventional extruder.
The MRSjump Extruder can processes a wide range of input materials, from regrind from mono- and multi-layer trays to material combinations which would stick together in a conventional thermal pre-treatment process (e.g. sheet regrind from PET/PE, GAG, certain copolymers).
The MRSjump Extruder Gneuss offers an optimum solution for post-consumer tray-to-tray recycling, which meets all requirements of completely circular modern food packaging.
Recycling and decontamination are for the first time made possible with the MRSjump Extruder, within one single extrusion step without upstream or downstream material treatment steps. This opens up new possibilities for the recycling of tray regrind.
