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.
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.
| 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 |
Throughput and change-part lists are on the Rotary Sticker Labeling page rather than in this note.
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.
Sleeve labels can cover complex bottle shapes and provide 360-degree branding opportunities, enhancing product visibility on the shelf.
Site requirements, air and power consumption sit with the Sleeve Labeling.
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 OPP Hot Melt Labeling Machine for High-Speed Lines.
Usually uneven tunnel temperature, wrong film orientation, or a bottle that is still warm from filling. Check the tunnel profile and the film direction before changing the speed.
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.
Hot melt glue applied at the leading edge, the trailing edge and the seam. The pattern and the pot temperature decide both the bond and how clean the bottle looks.
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.
