PET bottle washing&recycling system is used to recycle from waste PET bottles bales to clean PET flakes, which with capacity from 500 kg/h to 3000 kg/h.This processing of washing is consist of different working units. The final product PET flakes has a stable quality and various grade applications, especially for PSF ,POY manufacturer with big capacity. Recent year, RETECH is always developing and improving the design and production.

| Description | Characteristic |
| PET Containers | One-way bottles |
| Colors Fraction | PET bottles should be pre-sorted by color. If the percentage of color bottles is higher than 30%, we suggest customer to install the automatic color bottle sorting machine to achieve efficiency. |
| Base Cups | Included, if any, and should be PP or PE plastic. |
| Labels (shrunk or glued) | The production line is designed for removing label mechanically. All type of labels will be removed by mechanical action. It includes paper, BOPP, PET, PVC, etc. |
| Caps | PP, HDPE |
| Caps seals | EVA, PP ( floatable material ) PVC or rubber seals are not separable. |
| Glue | Hot melt, water borne. |
| Contamination | Mixed with the bottles could be present contaminations coming from the collection and storage of the postconsumer bottles or made by consumer. These contaminations include mud, sand, soil, glass, organics, paper, residual liquid, etc. Total contamination content should not exceed 10%. |
| Total Non-PET Containers | Non-PET containers max 2% of which |
| PVC Container | 0.5 -1% max |
| Polyolefins Container | 3 % max. It will only affect the output volume but not quality of end product. |
