Typical Recycling Process
The complete food Grade B2B PET bottle washing line may include the following stages:
1. Bale Breaking and Feeding
Compressed PET bottle bales are opened and fed evenly into the production line.
2. Sorting
Manual or automatic sorting removes non-PET materials,oversized contaminants,hazardous items,and heavily contaminated bottles.
3. Label and Cap Separation
A label remover machine separates loose labels and reduces the amount of PVC,paper,and other foreign materials entering the washing system.Caps and rings can be separated during subsequent sorting and density-separation stages.
4. Crushing
PET bottles are reduced into uniform flakes using a high-strength plastic crusher machine.
5. Friction Cleaning
High-speed friction washers remove dirt,sand,beverage residue,paper,and other surface contaminants from the PET flakes.
6. Hot Washing
For higher-quality applications,a hot-washing tank uses heated water and a suitable cleaning solution to loosen oil,adhesive,organic residue,and stubborn contamination.
7. Floating Separation
A floating tank in food safe plastic recycling equipment separates PET flakes from lower-density materials such as PP and PE caps,rings,and certain label residues.
8. Rinsing
Multi-stage rinsing removes detergent and remaining contaminants from the PET flakes.
9. Centrifugal Dewatering
A high-speed dewatering machine removes most surface water while preparing the material for thermal drying.
10. Thermal Drying
A hot-air drying system reduces residual moisture and improves the quality and storage stability of the finished flakes.
11. Fine Separation and Dust Removal
Air separators,zigzag classifiers,metal detectors,and other optional systems can remove lightweight materials,dust,metal particles,and remaining impurities.
12. Final Flake Collection
Clean PET flakes are collected,inspected,and packed for storage or further processing.

Finished Product
The food grade washing line produces washed and dried PET flakes with improved cleanliness and reduced contamination.Depending on the raw material and selected configuration,the finished flakes may be used for:
- Polyester fiber production
- PET strapping
- Recycled PET sheet
- Injection molding
- Thermoforming applications
- Non-food packaging products
- Further pelletizing or extrusion
- Production of recycled PET resin
For applications requiring recycled material for direct food-contact packaging,additional processes—such as advanced decontamination,solid-state polycondensation,melt filtration,and applicable regulatory certification—may be required.Food-contact suitability should be verified according to the target market and final application.
Construction and Materials
The FDA approved rPET flakes washing line can be manufactured with corrosion-resistant materials and hygienic processing components suitable for plastic washing applications.Stainless steel can be used for washing tanks,water-contact areas,piping,and other relevant components where required.The exact material grade,surface finish,and construction standard can be specified according to the customer’s production requirements.
