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.
A consistent shrink needs the right film direction, a controlled tunnel temperature profile and a bottle that does not deform. Steam tunnels give a softer shrink than hot air and suit thin-wall bottles. A wrinkle at the shoulder is usually a film or temperature issue, not a speed issue.
| 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 |
Site requirements, air and power consumption sit with the Rotary Sticker Labeling.
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.
Throughput and change-part lists are on the Sleeve 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.
The same question is worked through from another angle in Fully automatic labeling machine helps old customer to automate.
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.
Not without a change of the applicator. Sleeve and wrap-around are different machines with different film paths, so a plant running both normally has two labellers.
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.
