Flat-surface labeling machines apply labels and films to the top flat or curved surfaces of workpieces, such as boxes, books, and plastic shells. They offer both roller and suction methods, with selection primarily based on efficiency, accuracy, and bubble control requirements. Round bottle labeling machines apply labels or films to the circumference of cylindrical or conical products, such as glass and plastic bottles. They can perform circumferential, semi-circular, double-sided circumferential, and circumferential positioning labeling functions, and are mainly available in vertical and horizontal labeling methods.

Side-side labeling machines apply labels or films to the side flat or curved surfaces of workpieces, such as cosmetic flat bottles and square boxes. They can be used with round bottle labeling equipment for simultaneous round bottle labeling.

Automatic labeling machines can also be categorized by the labeling object, such as pallet labelers and irregular-shaped labeling machines. According to the labeling method, there are mainly suction labeling, roller labeling, brush labeling, air blow labeling, and wipe-on labeling. According to the degree of automation, they can be divided into manual labeling machines, semi-automatic labeling machines, and fully automatic labeling machines. According to function, there are single-sided labeling machines, double-sided labeling machines, multi-sided labeling machines, and integrated printing and labeling machines.
