A PET sheet bottle washing line is specialized in recycling used PET bottles into clean,high-quality flakes suitable for manufacturing sheet-grade PET.
The plastic sheet recycling equipment consists of a series of interconnected machine and equipment.The functions and usages of them are listed as follows:
Key Components & Process
Label & Cap Removal
Advanced separation systems (e.g.,air classifiers,label remover machine) eliminate plastic labels and caps (usually HDPE/PP) using mechanical friction,suction,or flotation.
Pre-Washing
PET bottles are rinsed with water or steam to remove surface dirt,sand,and light organic residues.
Crushing/Granulation
Bottles are reduced to small flakes (10–15mm) using a wet granulator or plastic crusher machine,which partially cleans the material during size reduction.
Hot Washing
Flakes are soaked in hot alkaline water (70–90°C) with 1–2% caustic soda to dissolve glue,grease,and stubborn residues.
Friction Washing
High-speed friction washing to remove remaining contaminants,ensuring purity.
Flotation/Sink-Float Separation
Water-based separation removes lighter materials (e.g.,PP/PE caps,labels) from denser PET flakes.
Drying
Centrifugal dewatering machine removes bulk water,followed by thermal drying to reduce moisture below 1%.
Final Inspection & Packaging
Flakes undergo quality checks before storage or pelletizing.
Technical Specifications
This PET sheet bottle recycling machine’s technical specifications includes power requirements(280V/380V/480V,3-phase,50/60Hz),material compatibility(PET bottles washing using water,soda,juice containers);some systems handle HDPE/PP caps.
Key Features
Our recycled plastic sheet machine offers numerous features,including configurating durability stainless steel contact parts,rock wool insulation in hot washer for energy efficiency,and automated chemical dosing for consistent cleaning.
