Clean PET flakes can be used to manufacture polyester staple fiber,filament yarn,strapping,sheets,thermoformed products,non-food packaging,and—when regulatory and quality requirements are met—food-contact recycled PET products.
Typical Recycling Process
The complete FDA approved food grade B2B PET bottle washing line generally follows the process below:
1. Bale Opening and Feeding
Compressed PET bottle bales are opened and fed into the pet bottle recycling machine line at a controlled rate.
2. Pre-Sorting
Large foreign materials,non-PET containers,hazardous items,and heavily contaminated bottles are removed.
3. Label and Cap Removal
Mechanical label removers separate loose labels and reduce contamination before bottle crushing.Caps and rings are later separated through density-based processing.
4. Bottle Sorting
Manual,mechanical,or optical sorting systems separate PET bottles by polymer type,color,and material quality.
5. Bottle Crushing
A high-performance wet or dry granulator reduces bottles into PET flakes while supporting dust suppression and stable particle sizing.
6. Pre-Washing
Initial washing removes loose dirt,residues,and surface contaminants from the crushed material.
7. Hot Washing
PET flakes are washed at elevated temperatures with controlled cleaning agents to remove adhesives,oils,organic residue,and difficult contamination.
8. Friction Washing
High-speed friction washers provide intensive mechanical cleaning and help detach remaining labels,dirt,and surface residue.
9. Float-Sink Separation
PET flakes sink in water while lighter materials such as PP and PE caps and labels float,enabling efficient polymer separation.
10. Multi-Stage Rinsing
Clean-water rinsing in food safe plastic recycling equipment removes detergent,suspended particles,and residual contaminants.
11. Dewatering and Drying
Centrifugal dewatering or air drying reduce moisture to the required level for storage or further processing.
12. Final Sorting and Quality Inspection
Optional optical sorting,metal detection,and quality inspection systems remove residual color,polymer,or foreign-material contamination.
13. Flake Storage and Packaging
Finished PET flakes are conveyed into silos,big bags,or automatic packing systems for shipment or further production.
