A sheet grade pet bottle washing recycling line is an automated,multi-stage sheet & bottle cleaning system designed to convert waste PET bottles into high-purity,clean flakes,often achieving <50ppm PVC contamination and <1% moisture.
Features of PET Sheet & Bottle Washing Line
Our pet sheet & bottle washing line’s key features include label removal,hot washing (80-95°C) to remove glue/oil,and efficient separation of PET from contaminants (PP/PE caps) using sink-float tanks and friction washers.
These features details include as follow:
Label Removal:
Improved Product Purity:By removing labels,especially full-body shrink sleeves (PVC/OPS),before the washing stage,the purity of final PET flakes can exceed 99%.
Reduced Downstream Contamination:Removing labels early prevents label pulp from mixing with PET flakes,reducing the load on hot washing and water treatment systems.
Increased Process Efficiency:Specialized label removal machines (using blades,friction,and airflow) can remove over 90-95% of labels, allowing subsequent washing steps to focus on residual glue and dirt.
Higher Quality rPET:Clean PET flakes without label remnants are crucial for high-grade applications like bottle-to-bottle recycling,which command higher prices.
Enhanced Equipment Life:Early removal prevents contaminants from damaging crushing blades and clogging machinery.
Hot Washing:
Superior Contaminant Removal:Hot water combined with caustic agents dissolves difficult materials that cold wash processes cannot remove,such as adhesives,grease,and food residues.
High-Purity Product (rPET):Provides the necessary cleanliness for producing high-quality flakes that can be used for food-grade packaging,increasing the resale value of the material.
Hygiene and Disinfection:Temperatures above 85°C kill bacteria and pathogens,making it a key step in meeting food safety standards.
Enhanced Efficiency:Reduces total processing time by up to 30% compared to solely cold washing,as it removes stubborn residue faster.
Optimized Performance:Ensures clearer and higher quality PET flakes,which are essential for producing new bottles,supporting a circular economy.
Lower Overall Production Cost:By reducing contamination issues in later stages (such as pelletizing using plastic recycling granulator machine),hot washing increases overall sheet & bottle cleaning system efficiency and product value.
Efficient Separation of PET:
High-Quality Output:Effective separation (using sink-float tanks) ensures that PET (sinks) is separated from contaminants like labels,caps,and glue (which float),ensuring the final product is suitable for high-grade applications.
Reduced Downstream Damage:By removing metals and impurities early (via magnetic removers),downstream crushing and processing equipment like label remover machine,and plastic crusher machine are protected from damage,reducing maintenance costs and downtime.
Lower Production Costs:Automated,efficient sheet & bottle cleaning system for separating materials reduces labor costs and increase efficiency in cleaning,ultimately requiring less energy for washing and purifying.
Increased Material Value:Clean,high-purity PET flakes (rPET) command a higher market price for reuse in producing new food-grade bottles,PET sheets,and fiber.
Optimal Process Efficiency:High-speed friction washing and flotation techniques ensure that labels,and residue are removed effectively to boost the overall recycling rate of packaging waste.
Sustainability and Waste Reduction:Efficiently separating PET from non-PET materials contributes to a circular economy,as it allows for the recycling of more plastic,which reduces landfill waste and lowers carbon dioxide emissions by substituting virgin material.
