Plastic Film Recycling with RUNI Screw Compactor

Plastic Film Recycling

PE film (Polyethylene film) is widely used in our everyday lives. From food packaging to grocery bags and medical packaging, you'll undoubtedly use this material daily. It is a product of great demand; however, it is non-degradable. This makes it essential to always send used plastic film to recycling centers with a PE film recycling machine. That way, used plastic film can be recycled and used for new plastic products.

Furthermore, burning PE film will pollute the air, making recycling the best choice of action. Our screw compactors can help you save energy in your PE film recycling process and gain the most from your resources.

The process of plastic film recycling involves shredding the material into smaller pieces, washing thoroughly, and then drying it. Traditionally, the drying process is carried out using hot air, centrifuging, and agglomerating. However, a considerable amount of this energy-demanding drying process can be replaced by pressing the water out of the wet PE film using a RUNI screw compactor SK370. Afterward, the plastic can be pelletized in a PE film recycling machine.

Press Water Out of the Washed PE Film

The drying/compacting process increases the dry matter content of PE film from 60% to 90% at a low energy consumption of only 24 kW per 1.000 kg PE film. When the screw compactor is installed right after the centrifuge, the process will be faster, increasing the capacity of the whole drying line. Your investment will quickly be recouped.

The RUNI Screw Compactor SK370 has been developed to operate on a fully automatic production line, 24 hours a day, processing approx. 800 kg per hour.

A de-compactor unit can be installed to loosen the PE film after it has been compacted. This can be useful if the PE film should be blown to next step.
