Use wrap-around application where a label follows a controlled cylindrical surface. Use front-and-back heads where two labels must be placed on opposed or related faces. Pack shape, orientation and label-to-feature tolerance determine the handling method.
Why this matters
Labelling quality depends on stable product spacing, surface condition, label web, peel geometry, sensor selection and wipe-down. A label applicator cannot correct a wet, tapered, rotating or badly controlled container.
Decision table
| Application | Best suited to | Key controls |
|---|---|---|
| Wrap-around | Cylindrical containers | Rotation, surface speed and overlap |
| Front-and-back | Oval or rectangular packs | Orientation and head-to-head registration |
| Top / bottom | Flat panels and trays | Height control and product support |
| Multi-panel | Cartons and shaped packs | Corner transfer and material flexibility |
| Print and apply | Variable-data labels | Data-to-pack identity and verification |
Information to collect first
- Measure pack geometry and taper.
- Define label position tolerance.
- Provide approved labels and production containers.
- Check condensation, oil or dust.
- Confirm reel direction and sensor contrast.
- Test smallest and least stable format.
Recommended method
- 1
Stabilise the pack before the peel point.
- 2
Set a repeatable product datum.
- 3
Match applicator and product speed.
- 4
Prove adhesive at production conditions.
- 5
Store recipes and first-off checks.
Common mistakes to avoid
- Selecting from label width alone.
- Changing delay to hide unstable product movement.
- Ignoring tapered label geometry.
- Testing clean dry packs when production is wet or oily.
- Approving each front/back label separately but not their relationship.
Questions people also ask
Can a round bottle use front-and-back labels?
Yes, but it needs controlled rotation or orientation and a repeatable relationship between labels.
Why do wrap labels wrinkle?
Taper, web misalignment, speed mismatch, surface contamination or poor wipe-down can cause wrinkles.
What causes label drift?
Inconsistent product sensing, slipping, web tracking or pack variation.
Should final labels be used in trials?
Yes; facestock, adhesive, liner, print and storage condition all affect performance.
