PLB700 High-Speed Automatic Starwheel Round Bottle Labeling Machine
PLB700 high-speed automatic round bottle labeling machine with starwheel bottle positioning for jars and bottles. 60–100 bottles/min and ±1.0 mm labeling accuracy.
PLB700
Product Introduction
The PLB700 High-Speed Automatic Round Bottle Labeling Machine is designed for fast and consistent labeling of small to medium-sized round containers.
Unlike conventional round bottle labelers that rely mainly on simple bottle stops, the PLB700 uses a starwheel bottle-spacing and positioning system to separate containers and guide them through the labeling station.
This structure helps maintain stable bottle movement at higher production speeds and improves label placement consistency.
The machine is suitable for round bottles and jars used for products such as chili sauce, peanut butter, jam, chocolate spread, cosmetic cream and other food or personal-care products.

Key Features
01
High-Speed Starwheel Bottle Handling
The PLB700 uses a starwheel instead of a conventional bottle stop for container separation and positioning. This structure provides more controlled bottle spacing during high-speed operation and helps improve production capacity.
02
Up to 100 Bottles per Minute
The standard labeling capacity is approximately 60–100 bottles/min. Actual production speed depends on bottle diameter, bottle height, label dimensions, label material, conveyor speed and product stability.
03
±1.0 mm Labeling Accuracy
The standard labeling accuracy is approximately ±1.0 mm. Actual accuracy may vary depending on container consistency, label quality and machine setup.
04
Touchscreen Control
The PLB700 uses a touchscreen control interface to centralize machine settings. Operators can conveniently adjust production parameters and monitor machine operation from the control panel. This reduces the need for multiple separate switches and makes machine adjustment more intuitive.
05
Bottle Detection Sensor
The machine is equipped with a sensor to detect incoming bottles. Once a bottle is detected, the sensor sends a signal to the control system and initiates the labeling sequence. This allows automatic synchronization between bottle movement and label dispensing.
06
Adjustable Label Sensor
The label sensor detects the position of each label on the backing paper. Its sensitivity can be adjusted according to different label materials. This helps improve dispensing accuracy and reduce missed or incorrect label feeding.
07
Heavy-Duty Chain Conveyor
The chain conveyor provides stable container transport and is suitable for continuous production. The standard conveyor width can be customized according to bottle dimensions and line requirements.
08
Wide Label Size Range
The PLB700 supports labels within approximately: Label Length: 20–300 mm; Label Height: 15–130 mm. The label range can also be customized according to the application.
09
Adjustable Label Roll System
The label feeding and rewinding structure is designed for continuous self-adhesive label application. Standard label roll dimensions include: Roll Inner Diameter: Φ76 mm; Maximum Roll Outer Diameter: Φ350 mm.
Containers enter the labeling machine through the conveyor. The starwheel separates incoming bottles and controls the spacing between containers before they reach the labeling station. A bottle detection sensor identifies each passing container and sends a signal to the control system.
The label sensor monitors the position of the self-adhesive label on the backing paper. When the bottle reaches the correct position, the labeling mechanism dispenses the label and applies it around the bottle surface.
How It Works
The machine can also be integrated with upstream and downstream packaging equipment for continuous production.

Finished Bottle Output
One of the key differences between the PLB700 and a conventional round bottle labeler is the starwheel bottle-handling mechanism. The starwheel controls the spacing and movement of bottles before labeling.
At higher line speeds, accurate bottle spacing becomes increasingly important. If bottles enter the labeling section too close together or with inconsistent spacing, the label dispensing timing can become unstable. The PLB700 uses a starwheel to separate and position bottles before labeling.
Starwheel Labeling System
Compared with a simple bottle-blocking mechanism, this design is particularly useful for: For customers requiring higher output than a conventional round bottle labeler, the starwheel structure provides a more suitable bottle-handling solution.
01
Higher production speeds
02
More consistent bottle spacing
03
Stable bottle positioning
04
Reduced bottle interference during labeling
05
Improved labeling consistency
06
Better synchronization with the labeling mechanism
07
Stable high-speed operation
The standard production speed is approximately 60–100 bottles/min. The final output is affected by bottle size, bottle stability, label length, label material, conveyor speed and upstream bottle supply. For larger bottles or long labels, the actual labeling speed may be lower.
Standard label dimensions are approximately: Length: 20–300 mm; Height: 15–130 mm. The machine can be customized for different label dimensions when required.
Labeling Capacity & Size Ranges
The standard container range is: Diameter: Φ30–100 mm; Height: 30–120 mm. For containers outside this range, the starwheel and bottle guiding structure should be evaluated before quotation.
Customer Benefits
01
Increase Production Capacity
The starwheel system allows continuous high-speed bottle handling with labeling rates of up to approximately 100 bottles per minute.
02
Improve Label Position Consistency
Controlled bottle spacing and sensor-based label dispensing help maintain more consistent label placement.
03
Reduce Manual Labeling Work
Automatic bottle detection, label dispensing and conveyor transport reduce repetitive manual operation.
04
