Polystar: Re-engineered recycling system

TAIWAN Polystar presented its re-engineered recycling system “Repro-Print” specially designed for processing heavily printed packaging film waste. The system is designedfor pelletising post-industrial film waste of PE, PP, BOPP and PS which are fully-printed, generated from in-house production. The pellets can be put directly back into film extrusion lines for reprocessing.

According to the manufacturer, there are three improvements from the previous model:

1. Triple degassing for a much enhanced degasification effect:
In addition to the double degassing zone in the first extruder, the venting area (the connection between the first and second extruder) serves as a third degassing section to further remove the ink and extra humidity level from the material.
2. Improved cutter compactor for faster and more stable material feeding:
An improved design of the cutter compactor now works superbly with printed BOPP film. The compactor cuts, dries and compacts the material that enables a fast and stable feeding from the compactor directly into the extruder.
3. Filtration before degassing: The re-positioning of filtration before degassing
ensures a superior degassing effect, producing excellent quality pellets from heavily printed material

Besides processing PE, PP (BOPP) heavily-printed film scraps and film on-roll, the Repro-Print can also process lightly printed or unprinted flexible packaging material with minimal degradation. Other types of waste such as raffia, woven bags and pre-washed film flakes that contain a higher percentage of humidity level are also applicable. The first re-engineered line has already been installed in the Philippines in a printing company located in Manila. The second line will be set up in Manchester, UK in August.
