Core Components & Specifications
Wet Plastic Crusher
Features a staggered, dual-scissor cutting action for high throughput and uniform flake size. Blades are crafted from D2 high-carbon steel for extended service life and can be easily sharpened and recalibrated.
Steam Hot Washer System
Effectively removes tenacious contaminants like glue, oil, and organic residues. Incorporates a PLC-controlled chemical dosing and temperature regulation system to ensure consistent and optimal washing performance.
Wet Plastic Bottle Label Remover
This machine utilizes mechanical friction and a continuous water spray to efficiently strip labels from PET bottles. It achieves a high removal rate without damaging the bottles, preparing them for the subsequent crushing stage.
PET Flake Purification & Separation Tank
A critical component for separating PET flakes from other plastics like polyolefins (PP/PE) based on density. Clean PET sinks while lighter contaminants float, ensuring a high-purity final product.

Frequently Asked Questions
What is a PET bottle washing line?
A PET bottle washing line is a specialized industrial system designed to clean and process post-consumer PET (polyethylene terephthalate) bottles for recycling. It typically includes stages like sorting, crushing, washing, rinsing, separation, and drying to produce high-purity flakes suitable for reuse in food-grade applications.
How does the PET bottle washing process work?
The process starts with de-baling and pre-sorting, followed by label/cap removal, wet grinding, sink/float separation, hot and friction washing, drying, and final packing. This multi-stage approach removes contaminants like labels, oils, and foreign materials, achieving up to 99% purity in output flakes.
What is the price range for a PET bottle washing line?
Pricing varies based on capacity (e.g., 500-2000 kg/hr), customization, and features like automation level. Entry-level lines start around $100,000-$200,000, while advanced food-grade systems can exceed $500,000. Contact us for a tailored quote based on your needs.
How to maintain a PET bottle washing line?
Regular checks include cleaning filters to prevent clogs, lubricating moving parts, and monitoring water quality. Our lines are built for low maintenance with durable components; we recommend daily inspections and quarterly professional servicing to minimize downtime.
What is the typical ROI for a PET washing plant?
The Return on Investment (ROI) depends on factors like local raw material cost, electricity rates, labor costs, and the market price for rPET flakes. However, our high-efficiency lines are designed to maximize profitability, and we can provide a detailed ROI analysis based on your specific operational context.
Do you offer post-installation support and spare parts?
Absolutely. We provide a comprehensive warranty, ongoing technical support, and a full inventory of critical spare parts to ensure minimal downtime and smooth, continuous operation of your plant.
How is the system customized for different types of input material?
Our system is modular. Based on the contamination level of your input bales (e.g., high sand, oil, or label content), we can add or enhance specific modules like pre-washers, dual label separators, or advanced sorting systems to guarantee the required output quality.
