Labelers are devices designed to apply labels to a wide variety of products. Labeling is an important part of the packaging process, not only because it provides relevant information about the product but also because it makes it more visually appealing to the consumer.

Consider the following to choose the most suitable model for your production line:
The shape of the packaging can also impact your choice. For example, a semi-automatic labeler is a good option for cylindrical or cone-shaped products as it allows you to stick the labels on without wrinkles forming.
Manual labelers are recommended for small-scale applications because they are easier to use.
Finally, to reduce machine downtime, you should ensure that label rolls and other machine consumables can be easily replaced without the intervention of a professional or the use of a specific tool.
Automatic labelers generally have a stepper motor and allow labels and tags to be applied quickly and evenly. Due to their high production capacity, they are ideal for labeling and tagging products on a large scale.
Their robustness and ease of operation are among their main advantages. They also require little maintenance, which requires specific tools. Maintenance and cleaning of the label feed rollers is just as easy and quick.
These labelers are also easily integrated into existing production lines. Some automatic machines can place different types of labels and tags at the same time.

CDA automatic labeler
Among the many automatic labelers available on the market, you’ll find several that will suit your type of production.
For example, some labelers have height-adjustable feet or castors that make them easy to integrate into any production line. Models with a 90° rotating application head allow labels and tags to be placed on the side and top of the product at a speed of up to 60 meters per minute.
Labelpack semi-automatic labeler
If you want to partially automate the labeling process, semi-automatic labelers are the best option. They offer precision, flexibility, and ease of use.
With this type of labeler, the operator positions the product and the machine applies the label using a foot pedal or automatically if it has a built-in sensor. It is ideal for sticking self-adhesive labels on cylindrical and cone-shaped products such as bottles, jars, and tubes. Labels and tags are applied without wrinkles forming, giving the product a neat and professional-looking presentation. Sensor models have an application speed similar to that of automatic labelers (up to 1,200 products per hour).

SATO Asia Pacific manual labeler
Manual labelers are often chosen in small businesses and stores because, unlike automatic labelers, they are ideal for simple tasks such as stock control and applying price tags. These labelers have several advantages, including ease of use and quick and easy label roll changes. In addition, they are lighter and smaller than automatic and semi-automatic machines. They are also the most suitable choice for industries with low production volumes.

Here are some other criteria to help you make your choice:
The label application method you choose will depend mainly on the configuration of the production line and the fragility of the product. Manufacturers can advise you based on the characteristics of the application for which the machine is intended.
Wipe-on method
This is the most common method of applying labels and stickers. When the product passes through the applicator, the label is pressed against the product by a brush or roller. The label and the product must move forward at the same time. To carry out this synchronization, the equipment needs an encoder that provides electrical impulses corresponding to the speed of the applicator and the product.
Blow-on method
This uses a vacuum to hold the label in a precise position on a perforated plate. As soon as the product passes by, the vacuum is stopped to release the label, and a controlled jet of compressed air is blown against the product’s surface. The blow-on method is the most commonly used with paper labels and allows labels of different sizes and shapes to be applied. These labelers can operate at very high speeds, applying up to 1,000 labels per minute. Because this is a non-contact labeling method, it is ideal for food products and fragile containers.
Tamp-blow method
The working principle is very similar to that of the blow-on method: the label is positioned and held on the plate by a vacuum system and then applied to the product with a jet of compressed air. The difference is that the tamp-blow method uses a pneumatic cylinder to bring the label closer to the product. This method is ideal for applying small labels and tags with extreme precision.
