Melt Filters for better Recycling of PET

Melt Filters

The usage of a new generation of tried-and-true ECO goods for recycling PET has been disclosed. The new features are first available in sizes appropriate for medium-sized recycling lines, taking into account the need for systems with a higher product throughput.

The former ECO 250 is replaced by the new ECO 350, while the former ECO 250 Twin is replaced by the new ECO 500, which can achieve capacities of up to 4,000 kg/h. This range is completed by the ECO 200.

The melt filter technique used by Laser Filters is based on the idea of continuous melt flow from the outside to the interior of a spinning, perforated disc for self-cleaning. The impurities that are being held back on the surface are scraped off and fed to the discharge system.

The new ECO filters, like the ERF filters, which are made for higher contamination, also have a modular structure, offering a variety of possibilities for tailoring the filter qualities to the particular application.

The amount of time the operator must spend performing maintenance and replacement duties is decreased with better access to the scraper system. The discharge now leaves the ECO filters’ front side, which is typically simpler for the user to access.

The melt filters are made to efficiently filter out pollutants including paper, wood, aluminum, silicone, and other materials while processing feedstock for very low viscosity polymers (primarily PET and PA). The closed discharge mechanism also avoids the development of black specks. Advancements in recycling technology such as the melt filter really help battle pollution in the field of recycling.

Because of this, extrusion systems that turn PET bottle flakes into food packaging films, packaging tape, and fibers, as well as PET repelletizing and compounding processes, are the traditional applications for ECO melt filters. ECO melt filters may achieve throughputs of 150 kg/h to 4,000 kg/h and are appropriate for single-screw or twin-screw extrusion lines, regardless of the pelletizing system or other downstream equipment.
