Wet Plastic Bottle Label Remover
Rumtoo’s wet label remover combines high-torque alloy knives with water-assisted scrubbing to peel off stubborn labels and pre-clean bottles, achieving >95% removal before hot washing.
- Jagged alloy knives shred labels
- Pressurized water for dual cleaning
- Boosts PET line throughput
Clean Bottles in One Pass
The wet label remover sits at the front of PET bottle lines. As bottles travel through the spinning rotor, claw-shaped alloy knives slice labels while water jets dislodge glue and rinse the surface. Labels drop into a separate chute, and cleaned bottles continue to granulation and washing.
- Simultaneous label removal and pre-wash reduce labor and downstream load.
- Wet process eliminates airborne dust from dry scraping systems.
- Label removal >95% with bottle breakage <1%, protecting bottle integrity.
Water-assisted rotor strips labels and rinses bottles before the washing loop.
Beneficios clave
Upgrading to a wet label remover immediately improves flake purity and line efficiency.
High Removal Rate
Jagged alloy knives and water jets remove >95% of shrink sleeves and paper labels before hot wash.
Cleaner Output
Pre-washed bottles send less dirt and glue downstream, reducing chemical usage and filtration load.
More Throughput
Continuous rotary design handles mixed PET/HDPE streams and keeps the washing line moving.
How the Wet Label Remover Works
A coordinated mechanical and hydraulic process prepares bottles for granulation.
Bottles enter the rotor through the top feed chute. Orientation is not critical.
Claw-shaped alloy knives tear labels while high-pressure water loosens glue and rinses bottles.
Labels exit through a collection chute; bottles continue clean to the washing or crushing stage.
Features & Design Highlights
Heavy-duty construction and easy maintenance keep the machine running across multiple shifts.
Alloy Knife System
Imported copper-welded knives are angled to claw labels while pushing bottles forward. Blades can be resharpened 2–3 times before replacement.
Water Jet Manifold
Adjustable spray bar directs fresh or recycled water to assist label removal and pre-clean bottle surfaces.
Label Collection Chute
Separated labels drop into a dedicated chute with water guidance, preventing recontamination of the bottle stream.
Low Breakage Design
Optimized rotor speed and bottle support keep breakage below 1% while still delivering high scrubbing force.
Aplicaciones
Ideal for any PET or HDPE bottle recycling line that requires fast, reliable label removal.
Post-consumer PET Bottles
Remove label sleeves from beverage bottles before crushing and washing.
HDPE Household Containers
Strip paper or shrink labels from detergent and shampoo bottles.
Mixed Bottle Streams
Handle municipal bottle bales with varying label types and adhesives.

Operation & Maintenance Tips
Maintain high removal rates with these quick practices.
Before Start-up
- Inspect knives for wear and tighten mounting bolts.
- Verify water supply pressure and nozzle alignment.
- Clear the label chute and drain to prevent buildup.
During Operation
- Feed bottles evenly to avoid clogging the rotor.
- Monitor label discharge to confirm proper separation.
- Adjust knife gap or spray intensity if removal rate drops.
Routine Care
- Sharpen or replace knives after 300–500 hours.
- Lube bearings and check seals per maintenance schedule.
- Flush the housing and chute to remove residual glue and pulp.
Preguntas frecuentes
How often do the knives need maintenance?
Check knives every 300–500 operating hours. They can be resharpened several times before replacement to maintain peak removal efficiency.
Can it process both PET and HDPE bottles?
Yes. The rotor handles PET beverage bottles, HDPE household bottles, and mixed bottle streams with shrink labels or paper sleeves.
What advantages does the wet method provide?
Water assists knife action, reduces dust, and pre-washes bottles by removing sand and grit before granulation.
Does it remove glue completely?
It removes most surface glue. For especially stubborn adhesives on PET, pair the machine with a downstream hot washer to soften residues.
