Labeling Machines for B2B Beverage Production

Sleeve, OPP or sticker: what decides the choice?

A full-body sleeve covers the whole bottle and gives the most design freedom, at the cost of film and a shrink tunnel. An OPP wrap-around label is the cheapest per unit at high speed. A sticker suits short runs and curved surfaces where a wrap is impractical.

Why does label position drift?

The label is positioned relative to the bottle, so any variation in bottle rotation, conveyor speed or label feed shows up as drift. On a round bottle the orientation is set by a roller or a star wheel; on a square bottle it is set by a mechanical aligner. Drift is usually a bottle handling problem, not a label problem.

The specification sheet for the Rotary Sticker Labeling carries the figures quoted here.

Where does the labeller sit in the line?

After the filler and before the packer, normally with an accumulator on each side. The labeller is the most frequent short-stop on many lines, so the accumulator size in front of it decides whether a label roll change reaches the filler or not.

Throughput and change-part lists are on the Sleeve Labeling page rather than in this note.

What decides label adhesion on a wet bottle?

Surface energy, bottle temperature and glue choice. A cold bottle straight from the filler carries condensation, and a water-based adhesive will not bond to it. Hot melt handles a damp surface better, which is why it dominates high-speed beverage lines.

The same question is worked through from another angle in How to Automate Labeling for Large Bottling Lines.

Why does a label need a vision check?

Because a missing or skewed label is a customer reject that the line cannot see. A camera at the labeller outlet with a reject gate catches it at the source, before the packer hides it inside a case.
