B2B PET Bottle Washing Line
Our B2B Grade PET Bottle Washing Line is an advanced recycling solution engineered to convert post-consumer PET bottles into premium-quality PET flakes suitable for Bottle-to-Bottle (B2B) recycling applications. Designed with cutting-edge sorting, washing, separation, and purification technologies, the system delivers exceptional flake purity while maximizing production efficiency and minimizing resource consumption.
Transform Post-Consumer PET Bottles into Food-Grade PET Flakes
Our B2B Grade PET Bottle Washing Line is an advanced recycling solution engineered to convert post-consumer PET bottles into premium-quality PET flakes suitable for Bottle-to-Bottle (B2B) recycling applications. Designed with cutting-edge sorting, washing, separation, and purification technologies, the system delivers exceptional flake purity while maximizing production efficiency and minimizing resource consumption.
The line effectively removes labels, caps, rings, metals, foreign polymers, adhesives, organic residues, and other contaminants through a carefully engineered multi-stage process. The resulting PET flakes meet the stringent quality requirements for food-grade packaging, beverage bottles, polyester fiber, sheet extrusion, and other high-value PET applications.

| # | Stage | Process | Description | Machines Involved |
|---|---|---|---|---|
| 1 | Material Feeding & Preparation | Bale Opening & Pre-Screening | PET bottle bales are conveyed, opened, and screened to remove loose dirt, sand, glass, stones, and oversized contaminants before entering the washing process. | Conveyor Belt → Bale Breaker → Trommel |
| 2 | Bottle Cleaning & Pre-Sorting | Delabeling & Bottle Purification | Bottles are conveyed through the cleaning section where labels are removed, bottles are optically sorted to eliminate non-food-grade containers, and surface contaminants are removed prior to manual quality inspection. | Twin Screw → Label Remover → Bottle Sorter → Pre Washer → Sorting Belt |
| 3 | Flake Production & Density Separation | Size Reduction & Material Separation | Bottles are granulated into uniform PET flakes. Float-sink separation removes PP/PE caps, rings, and lightweight contaminants, followed by initial moisture removal and air classification. | Crusher → Floating Tank → Spin Dryer → Pneumatic Drying System → Zig Zag Separator |
| 4 | Intensive Flake Washing | Hot Washing & Multi-Stage Rinsing | PET flakes undergo two-stage hot washing followed by multiple rinsing stages to remove glue, adhesives, organic residues, beverage contamination, oils, detergents, and fine impurities while maintaining food-grade cleanliness standards. | Hot Washer → Spin Dryer → Hot Washer → Spin Dryer → Rinsing Tank → Spin Dryer → Rinsing Tank → Spin Dryer |
| 5 | Final Drying & Purification | Moisture Removal & Air Cleaning | Final mechanical drying and air classification remove residual moisture, dust, label fibers, films, and lightweight particles to produce clean, dry PET flakes. | Pneumatic Drying System → Zig Zag Separator |
| 6 | Optical Quality Control & Packaging | Advanced Flake Sorting & Storage | High-precision optical sorting removes off-color flakes, foreign polymers, and metallic contaminants before the finished food-grade PET flakes are transferred to the packaging silo. | PET Flake Color Sorter → PET Flake Polymer Sorter → PET Flake Metal Sorter → Packaging Silo |
