Polyethylene Terephthalate or PET products are 100% recyclable and are the most recycled plastic worldwide. PET can be easily identified by its recycling code #1. To fully turn plastic bottles to fine PET regrind, our systematic solution of PET washing line can separate caps, adhesive and film from PET bodies.
From Baled to Unbaled
Whether baled or not baled, the first step is to break it down. The PET bales are delivered by metal conveyor and then enter a debaler. The rakes of the debaler snap off the straps, freeing the bottles. If the bottles are heavily contaminated, they will go through a trommel. A slow rotation drives out sands and dirt.
The labels wrapped on each bottle are not our target materials. Thus, we use a mechanical label remover to peel off 90% of the labels. The sharp knives rip off the plastic labels inside the chamber.
A granulator is a perfect machine for size reducing and washing the bottles. With a special force-feed device, the bottles directly enter the crushing chamber. As a result, 12mm flakes go to the subsequent process.
Friction Washing and Density Separation
The rollers of the density tank make sure all materials are submerged and fully wet.
Buoyant materials: caps and labels, are gathered from the water surface.
Sink-float tanks pick up sinking materials (PET flakes) by an auger from the bottom.
Hot Washer (Label Remover)
This is a necessary step for hot wash but not necessary for cold wash. Adhesive (glue) remaining on bottles is challenging. When hot washing, using detergent and proper warm water and stirring constantly can efficiently dissolve the glue.
This is a vital step to increase product quality.
The PET bottle recycling system developed by Wiscon guarantees PET flakes are extrusion and injection grade.

Once a PET bottle recycling system is finished, Wiscon tests the PET washing line with similar materials to show capability and output. Seeing is believing, so you are greatly welcome to present and witness with us on site. If you cannot make in person, detailed videos and numerous photos will be prepared for you to exam.
