1. What is a labeling machine?
A labeling machine is an automated device used to quickly and accurately apply labels (such as self-adhesive labels, paste labels, etc.) to specific positions on products, packaging, or containers. It replaces inefficient and error-prone manual labeling and is a key piece of equipment on modern production lines.
2. How does a labeling machine work?
Using the most common self-adhesive labeler as an example:
(1) Unwinding: The backing paper of the label roll is reverse peeled by a peeling plate.
(2)Peeling: The label, due to its front-end adhesive, separates from the backing paper and extends ready for application.
(3)Application: The product arrives at the labeling position via conveyor belt or turntable; a sensor sends a signal.
(4)Press-on/Rolling: The labeling head presses the label onto the product surface, or the product passes a roller mechanism that smoothes and compacts the label.
(5)Rewinding: The peeled backing paper is collected by a rewind reel.
3. What key factors should be considered when selecting a labeling machine?
(1)Product & Container: Shape (flat, round, square), size, material (plastic, glass, metal).
(2)Production Requirements: Line speed (units per minute), capacity requirements.
(3)Label Specifications: Label material (paper, PET, PVC, etc.), size (length, width), shape (e.g., custom die-cut).
(4)Labeling Position & Accuracy: Where does it need to be applied (top, side, wrap-around)? How high is the precision requirement (±0.5mm or higher)?
(5)Automation Integration: Does it need to connect to existing production lines (like fillers, cappers, packers)? What interfaces are needed?
(6)Budget: Initial investment cost and long-term maintenance and operating costs.
4. Our production line is very fast. Can the labeling machine keep up?
Yes, high-end fully automatic labeling machines can achieve speeds of hundreds or even thousands of units per minute. When selecting a machine, simply inform the equipment supplier of your production line speed, and they will recommend a model that matches it.
