Our ECO melt filters are capable of processing a wide range of polymers but due to their special design are mainly employed in PET and PA applications. All solid or elastomer foreign particles such as gels, black specs, paper, wood, aluminum, copper, rubber, silicone or high-melting polymer composites are efficiently removed. In particular, there is significantly less degraded PET in the form of black specks.

For this reason, the classic application for ECO melt filters is extrusion systems, for instance where recycled PET bottle flake is converted into food packaging films, packaging tape, and fibers. PET repelletizing and compounding processes in general are other potential areas of use.

ECO melt filters can in principle be used in any extrusion line – either single or twin-screw and irrespective of the type of pelletizing system or other downstream unit.

Key Features

  • Continuous operation with a constant pressure on the outlet side
  • No need to replace the screen for several weeks, or possibly months, depending on the material and the applicationExtremely low melt losses
  • Absolutely clean filtration surface during the total time in operation
  • Up to 1.5% contaminants removed (we recommend our ERF filter for higher contaminant contents)
  • Completely closed system with no entrapped air
  • Short contaminant residence times in the filter
  • Consistent melt flow without dead zones or degraded polymer
  • Suitable for all polyolefins, polystyrenes, PET and PA
  • Better mixing and homogenizing of highly filled melts
