Bottling Beer

Bottle Labeling

Bottle labeling in the sequence of processes follows bottle filling, which may itself be preceded by tunnel pasteurization.

Types of Labelers

The principal types of labelers used in the brewing industry are pressure-sensitive, rotary, and tandem.

Pressure-Sensitive Labeler

These units are used in the wine industry and food industry, but are more typically used in the cosmetic, pharmaceutical, and soap industries. Pressure-sensitive or self-adhesive labels are also used in the craft brewing industry though not as much as paper labels. Pressure-sensitive labels are applied from a coiled strip of waxed carrier (also called "backing") paper.

Rotary Labeler

Rotary labelers are machines for which the bottles must be transferred from the bottle conveyor into the labeler carousel (see Figure 17.5). Rotary labelers operate at higher speeds than pressure-sensitive and tandem labelers. They are equipped to apply front, back, full wrap, and neck labels. Rotary labelers have two main advantages.

Tandem Labeler

An in-line labeler is a type of machine for which the bottle travels in a straightforward motion and the label or labels are applied while the bottle is moving along the bottle conveyor. Tandem labelers cannot do front and back labels at the same time, and they are not well-suited for applying neck labels. Unlike other rotary labelers, the tandem labeler does not bond labels with a full width of glue, but rather with only two vertical strips, one at each side of the label.
