A PET bottle washing machine is the equipment used to separate the caps from the bottles. It also removes impurities such as sediment, minerals, and wood pieces that are trapped in the caps and bottles.
What is a PET Bottle Flakes Washing Machine?
A PET bottle flakes washing machine is used to automatically separate floating chips and effectively separate sand and paper chips from various plates.
The PET bottle washing machine is one of the ideal pieces of equipment for the plastic bottle recycling line. It is suitable for further separation and cleaning of impurities after polyester cleaning, which makes the bottle chips cleaner.
Principle of PET Bottle Washing Machine
A PET bottle flakes washing machine uses the density of water to complete the separation. The density of water is 1 g/cm³, and denser materials will sink and less dense materials will float.
Take PET bottle recycling as an example, when the material flows enters the sink and float separation tank filled with water, PET plastic will sink to the bottom, while PP/PE bottle caps will float to the top.

Complete PET Bottle Recycling Line Integration
A modern PET bottle recycling plant is not just about having a single machine — it’s about integrating a complete line where each unit works together to maximize efficiency, purity, and output quality. Our PET bottle washing machine is designed to work seamlessly with various auxiliary machines to form a complete PET bottle recycling solution. Below is a detailed overview of the integration process and equipment configuration.
Plastic Bottle Label Removing Machine:
The plastic label remover machine is the first step in the recycling line. This machine effectively strips shrink labels (PVC, PETG) from PET bottles without damaging the bottles themselves. It significantly reduces manual labor and improves the efficiency of subsequent processes.
PET Bottle Crushing Machine:
After labels are removed, the bottles are fed into a plastic crusher machine (also known as a PET bottle shredder). The crusher reduces the bottles into small, uniform flakes that are easy to wash and dry. A high-speed rotor ensures consistent particle size and high throughput.
Frictional Washing Machine:
The friction washer provides mechanical scrubbing of PET flakes. It uses high-speed paddles to create intense friction between flakes, removing fine particles and sticky residues. This step enhances the overall cleanliness of PET flakes.
Hot Washing Tank:
The hot washer tank plays a vital role in removing adhesives, oils, and stubborn contaminants. With temperature control, it ensures that PET flakes are cleaned thoroughly without damage, which is crucial for applications like food-grade packaging or fiber production.
Plastic Dryer Machine:
After washing, the PET flakes pass through a centrifugal dryer and a hot air drying system. The dewatering system removes most surface moisture, while the hot air dryer ensures that the flakes meet moisture content requirements for storage or further processing (like pelletizing or fiber extrusion).

Why PP PE Separation?
The cap and bottle materials are different. The cap is PE polyethylene low-pressure plastic, the bottle is PET polyester plastic; their melting point are not the same. If not separated will contaminate each other. When melting and utilizing, they must be handled separately.
Why is PP PE Separation Important?
- Ensure high-purity PET flakes for pelletizing and fiber production.
- Improve recycled product quality (strength, clarity, stability)
- Prevent contamination during PET pelletizing or sheet extrusion
- Meet food-grade or textile industry standards for recycled PET
Industrial Bottle Washing Machine Highlights
- The PET bottle flakes washing machine’s size and number of paddle rotors can be customized
- Material contact parts are made of stainless steel
- The industrial bottle washing machine is large enough and deep enough
- Industrial bottle washing machine has low energy consumption and high efficiency
- Longer service life due to less wear and tear on the internal parts of the PET bottle washing machine
FAQs of PET Bottle Washing Machine
What cleaning methods are used in the PET bottle washing process?
The cleaning process usually combines cold water washing, hot water washing, friction washing, and floating separation to remove labels, glue, oil, and other contaminants.
Can the machine be customized?
Absolutely. The PET bottle washing machine and complete recycling line can be customized in terms of capacity, layout, auxiliary equipment, and automation level to fit your specific needs.
