Product Introduction：

A fully automatic sleeve labeler is an automated packaging machine that automatically cuts heat-shrinkable film labels (sleeve labels), precisely applies them to containers, and uses a heat-shrinking process to ensure the labels adhere tightly to the container surface. This equipment integrates feeding, labeling, and shrinking into a single unit. It is widely used in the food and beverage, pharmaceutical, personal care, and seasoning industries, and is an indispensable piece of packaging equipment in large-scale production lines for bottled and cup-packaged products.Unlike traditional labeling methods, sleeve labelers use heat-shrinkable film labels. By applying heat, the labels shrink uniformly and adhere tightly to the container surface, achieving 360° full-circumference coverage. This process offers advantages such as distortion-free label graphics, strong anti-counterfeiting capabilities, and an elegant appearance, making it particularly suitable for scenarios requiring enhanced product quality and brand recognition. As one of the most technologically advanced pieces of equipment in the final packaging stage, the sleeve labeler has earned widespread recognition from customers for its excellent high-speed stability and unique, agile design.

Features：

1. High labeling accuracy with consistent and reliable quality

The system employs a PLC-controlled servo motor to drive a synchronized cutting mechanism, combined with fiber-optic sensors for precise positioning, ensuring accurate label placement and consistent cutting lengths. High-end models feature intelligent photoelectric tracking and automatic alignment correction systems, achieving positioning accuracy of ±0.3mm. The equipment includes functions such as automatic origin detection, label break detection and alarm, and no-product no-labeling, effectively preventing missed labels and label waste.

2. Extremely high production efficiency and robust capacity

Fully automatic labeling machines support both integrated operation with production lines and standalone operation. Standard models achieve labeling speeds of 50–200 bottles per minute, while high-speed models reach 300–800 bottles per minute. Dual-head labeling machines can double output within the same cycle, making them particularly suitable for medium to large-scale continuous production lines.

3. Wide Applicability and Strong Compatibility

The equipment accommodates a variety of container shapes, including round, square, oval, rectangular, curved bottles, and irregular-shaped cups, and supports multiple heat-shrink film materials such as PVC, PET, and OPS. Thanks to modular design and a quick-change mechanism, switching between different bottle types can be completed in 2–15 minutes.

4. Intelligent Control and User-Friendly Operation

Equipped with a color touchscreen HMI supporting both Chinese and English interfaces, the machine operates unattended during production and features comprehensive warning systems and self-diagnostic capabilities. Select high-end models offer IoT-enabled remote operation and maintenance, enabling real-time monitoring of equipment status, fault alerts, and predictive maintenance.

5. Durable Construction and Compliance with Sanitary Standards

The entire machine features a protective housing made of SUS304 stainless steel and an aluminum alloy frame, ensuring stability and rust resistance while meeting food-grade GMP production standards. Core electrical components from international brands such as Siemens, Mitsubishi, and Schneider Electric guarantee continuous, stable 24/7 operation.

6. Low Labeling Costs and Exquisite Packaging Results

Utilizes heat-shrink film labels, with material costs significantly lower than those of self-adhesive labels. After shrinkage, the label wraps 360° around the product without distortion, creating an elegant and sophisticated appearance that effectively enhances product value and brand recognition.

7. Selectable shrinkage methods for flexible adaptation

The equipment can be configured with either a steam shrink tunnel or an electric shrink tunnel based on product characteristics: the steam method offers superior shrinkage results and is suitable for moist products; the electric method allows for immediate boxing after shrinkage and is suitable for dry products. Both methods have their respective advantages.
