Gernep manufactures front-and-back labelers with distinct labeling technologies depending on the application. We focus exclusively on rotary labelers, which means the bottles or containers are transferred to a rotary turret and positively handled during label application.
Rotary labeling machines allow us to apply two labels to the same bottle or container by rotating it 180⁰ between the two applications. Each bottle is held between a bottle plate and a centering bell while traveling on the rotary turret. The rotation of each bottle plate is controlled either mechanically, with cam and steering cross, or electronically with servo motors.
Bottle handling is critical for front-and-back label application because the label’s position (or facing) must be centered perfectly on the bottle panel. Ideally suited for panel applications, Rotary labelers hold bottles firmly to control the rotation/angle of the bottles as well as to wipe the applied labels and ensure adherence. Controlling the bottle rotation proves practical to affix front-and-back labels to round, oval, square, or rectangular bottles compared to inline labelers.
Also referred to as Panel Labeling, front-and-back labeling is widespread in personal care, cosmetic, chemical and food industries. Typical examples are soap, shampoo, and ketchup bottles, as well as beer and wine bottles.
As an alternative to front-and-back labeling, single labeling for multiple square or rectangular bottle panels is possible; in such cases, we use a 3, 4, or 5-panel labeler.
Pressure-sensitive panel labeler
for front-and-back applications
In industries like food, personal care, dermatology, and cosmetics, where front-and-back labeling is needed, most manufacturers will use PS (pressure sensitive) labels. Using a pressure-sensitive labeler is a clear advantage in any marketing-driven industry. Changing size and shape does not require purchasing label format parts, reducing changeover times when running different products because only the bottle format parts will be required. Height adjustment may be required; however other parameters are memorized in the PLC.

Cold glue cut & stack labeler
for front-and-back applications
Most cold glue labelers are found in breweries these days, but they are also common in the wine and food industries. In many states and provinces, beer bottles are collected and washed to be reused often. Cold glue labels are ideal for washing machines. They are easy to remove from the bottles (just think of your beer bottles in a cooler when the ice has melted), and they disintegrate quickly to avoid clogging the drain of the bottle washers. Cold glue label application is possible on wet bottles, provided you are using suitable glue, unlike pressure-sensitive labels or hot melt applied labels. Finally, the low cost of labels makes it an attractive choice for competitive markets like beer.
Buying a new labeling machine can be a big investment depending of your production requirement. We hope to be able to demystify the different types of labeling systems and help you make a sound decision...
