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 |
Reference unit for this duty: the Rotary Sticker Labeling.
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.
The unit behind this configuration is 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 Hot Glue Labeling: Where the Glue Pattern Decides the.
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.
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.
Usually too little glue, a cold bottle, or a seam pressed before the glue sets. Check the glue pattern and the bottle temperature before changing the speed.
