As one of the core equipment in the packaging field, labeling machines attach labels to product surfaces through automated or semi-automated methods, and are widely used in various industries such as food and beverage, pharmaceuticals, daily chemicals, and electronics. Based on their working principles, application scenarios, and structural characteristics, labeling machines can be divided into the following four primary categories.

The flat surface labeling machine is a labeling device specifically designed for flat or nearly flat products, suitable for surface labeling of various flat bottles, paper boxes, cartons, plates, and other products. The side labeling machine primarily performs labeling operations on the sides of products, suitable for round bottles, square bottles, irregular-shaped bottles, and other products with side labeling requirements, commonly seen in labeling beverage bottles, condiment bottles, medicine bottles, etc.

Circumferential labeling machines are specialized in applying full or half-circumferential labels to cylindrical, conical, and other products with circumferential surfaces. They are essential equipment in the beverage, beer, canned food, and other industries. Fully automatic online labeling machines are high-end labeling equipment that integrate advanced automation technology and intelligent control systems. They are primarily used in large-scale automated production lines, enabling seamless integration with other production processes and facilitating the full automation of product production and packaging. These devices are typically equipped with high-precision conveyor systems, visual inspection systems, intelligent control systems, etc., capable of performing a series of operations such as automatic product identification, positioning, labeling, and inspection.
