Polystar plastic film recycling machines

For companies looking to recycle plastic film waste, Polystar offers a range of one-step machines that are designed for the reprocessing of polyethylene and polypropylene flexible packaging material.

The machines are designed to be simple to operate and easy to maintain, all the while taking up minimal space and time. Their output comes in the form of high-quality plastic pellets that can be fed straight back into the manufacturing process, saving on raw material costs as well as on waste disposal.

This pelletising system — with its integrated cutter compactor — eliminates the need for pre-cutting in most cases and ensures the material spends less time in the extrusion process to minimise degradation.

In addition to the double degassing in the first extrude, the venting area — the connection between the first and second extruder — serves as a third degassing section (optional) to further remove the ink and extra humidity level from the material.

The unvented extruder has a short screw L:D ratio, in which the material travels in the extruder for the shortest time and distance. This results in minimal change in material property and higher output compared to a vented extruder. Furthermore, the repositioning of filtration before degassing ensures a good degassing effect, producing high-quality pellets from heavily printed material.
