The Taiwanese equipment company Polystar has introduced the Repro-One, its newest piece of equipment that is designed to process both soft and rigid plastics. Polystar says Repro-One integrates a heavy-duty single-shaft shredder with a pelletizer, offering a one-step process for recycling of soft and rigid plastics.
The recycling machine is ideal for companies involved in handling polypropylene (PP) or polyethylene (PE) film, according to the manufacturer.
According to Polystar, the recycled pellets produced by the shredder can be put directly back into tape extrusion lines or blown/cast film lines for immediate reprocessing. The recycled pellets can be loaded in high percentages and still produce high-quality fabric with good tensile strength and elongation.
In Repro-One, plastic scrap is processed by a single-shaft shredder for initial size reduction. The ram inside the shredder continuously pushes the bulky material towards the rotating shredder.
After shredding, the material is fed directly into the extruder. The material is then degassed (if the material is printed) and filtered before the die-face pelletizing process.
The integrated shredder can effectively process large-sized scrap, such as jumbo bags, raffia, tape, rope, lumps from extrusion startup and woven and nonwovens without preshredding in advance, the manufacturer says.
