PET Recycling Pre-Treatment

Butelka plastikowa Maszyna do usuwania etykiet

Q: Jaka jest typowa szybkość usuwania etykiet przez maszynę?

Under standard production parameters, the machine achieves a de-labeling separation rate exceeding 98% for compressed or loose post-consumer PET beverage bottles.

Q: What is the difference between dry and wet label removal systems?

The dry model utilizes high-pressure centrifugal suction and a Zig-Zag air classifier to peel and suck away labels without water usage. The wet model injects hot or ambient water into the chamber, softening hot-melt adhesives and pre-washing surface sand.

Q: How are the peeling knives maintained and replaced?

The central rotor is fitted with bolt-on, hard-faced alloy teeth. Individual blades can be easily rotated or replaced independently without requiring whole-shaft disassembly, keeping maintenance downtime minimal.

Q: Can this machine handle baled or crushed plastic bottles directly?

Baled bottles should first pass through a bale breaker or de-baler to loosen compacted bricks into individual containers before entering the infeed hopper for optimal de-labeling throughput.

Q: Which types of bottles and label sleeves can be processed?

The machine handles standard round, oval, and square bottles made of PET, HDPE, or PP, stripping PVC, PETG, and OPS heat-shrink sleeves as well as wrap-around OPP film labels with high efficiency.

Q: Where does the label remover sit within a PET bottle recycling line?

It is positioned directly downstream of bale breaking and trommel pre-screening, immediately preceding optical sorting, wet granulation, and hot washing stages.

Q: Does the peeling mechanism damage or crush the PET bottle bodies?

No. The specialized rotor clearance and inclined transport flight geometry are calibrated to score and rip labels without puncturing or flattening the bottle body, preserving bottles for optical color and metal sorting.

High-capacity mechanical de-labeling equipment engineered to strip over 98% of PVC shrink sleeves and OPP wrap-around labels from post-consumer PET bottles before crushing and washing.

Achieves ≥ 98% label separation while preserving bottle structural integrity.
Available in dry pneumatic and wet water-injection configurations.
Bolt-on tungsten-carbide alloy knives with quick individual replacement.
Drastically reduces PVC and glue contamination in downstream PET flakes.

Zasada działania maszyny do usuwania etykiet

The PET bottle label remover achieves over 98% peeling efficiency through a coordinated three-stage mechanical and aerodynamic workflow.

Krok 1

Screw-Driven Infeed

Loose bottles enter through the heavy-duty hopper where internal screw flights meter and convey containers continuously into the peeling chamber.

Krok 2

Dynamic Surface Scratching

High-speed rotary alloy teeth score and peel shrink sleeves against stator counter-blades without puncturing or crushing the bottle body.

Krok 3

Pneumatic Label Extraction

A powerful suction blower and cyclone separator draw lightweight detached labels away, discharging intact de-labeled bottles onto the sorting belt.

Key Technical Advantages

Engineered to optimize recycled PET flake purity, protect washing line water quality, and reduce operating costs.

>98% Label Separation Rate

Removes virtually all shrink-sleeve PVC, PETG, and PP wrap-around labels before granulation, preventing downstream PVC contamination.
Zero Bottle Damage

Maintains bottle shape and volume, enabling high-accuracy optical sorting and sensor detection prior to wet granulating.
Dry & Wet Dual Configurations

Choose zero-effluent pneumatic dry de-labeling or wet hot-water wash integration to dissolve stubborn glues and remove surface sand.
Bolt-On Hard Alloy Blades

Individual wear-resistant alloy teeth are fastened with high-tensile bolts, allowing quick indexing and replacement without rotor removal.

Core Equipment Components

Precision mechanical construction designed for heavy 24/7 continuous industrial bottle washing lines.

Plastic bottle label removal machine peeling chamber assembly

Main Peeling Chamber & Rotor Assembly

The heavy-walled cylindrical barrel houses a reinforced central spindle equipped with spirally staggered claw blades. As bottles travel through the chamber, the knives scrape off label adhesives and sleeves cleanly while the continuous barrel clearance prevents bottle crushing.

Pneumatic Blower & Cyclone Separation

Positioned at the discharge chute, an adjustable centrifugal blower draws detached label films into a cyclone collector while heavier bottles fall onto the downstream inspection conveyor, ensuring clean, continuous label evacuation without human intervention.
