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.
Through the conveyor and an accumulator, not through a mechanical link. The labeller runs slightly faster than the filler and the accumulator absorbs the difference. A labeller matched exactly to the filler speed will stop the line at the first roll change.
| Label type | Cost per unit | Best for |
|---|---|---|
| OPP wrap-around | Lowest at volume | High-speed round bottles |
| Full-body sleeve | Higher film cost | Full coverage and shaped bottles |
| Self-adhesive sticker | Middle | Short runs and flat or curved panels |
| Paper label with glue | Low material, slower | Glass bottles and craft products |

A consistent circumference and no sharp undercut where the film cannot follow. Sleeves shrink around the shape, so a bottle with a deep waist needs a film with the right shrink direction. The bottle and the sleeve are designed together.

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.
The same question is worked through from another angle in The Role of Labeling Machines in Bottled Beverage Production.
It is matched to the filler, typically with margin above the filler rating so that a short stop does not reach the filler. The practical limit is the shrink tunnel dwell time, not the sleeve applicator.
At high volume, an OPP wrap-around label usually is, because the film is thinner and the machine runs faster. A sleeve costs more per unit but covers the whole bottle and allows full-body design.
Perforation strength, film tension and tunnel temperature act together. A tear that appears after shrinkage usually means the perforation was cut too deep for the film gauge.
With two applicators or a combined unit, yes. They are separate stations with separate film paths, so the line needs the space and the changeover time for both.
