Adhesion and surfaces
Label Adhesion and Bottle Surface Guide.
Check the pack and label construction before treating lifting as a machine fault.

A labeller can place and wipe a pressure-sensitive label, but it cannot compensate for every unsuitable adhesive, contaminated surface, severe compound curve or unstable container. Evaluate the label construction, bottle material and production environment together.
| Factor | What to observe | Practical implication |
|---|---|---|
| Surface cleanliness | Oil, mould-release residue, dust, product splash, fingerprints or cleaning residue. | Contamination can reduce initial tack or create local lifting even when placement is correct. |
| Temperature and moisture | Cold-filled packs, condensation, warm labels, changing storage conditions. | Trial the real production condition rather than only dry room-temperature samples. |
| Bottle geometry | Taper, compound curves, shoulders, recesses, seams and textured panels. | A flat label may wrinkle or lift when forced onto a surface that changes in more than one direction. |
| Container flexibility | Thin sidewalls, vacuum panel movement or distortion under guides and wipe pressure. | The product may need additional support or a different label panel and application route. |
| Label construction | Face material, stiffness, adhesive, die-cut shape, liner release and print or varnish. | The label supplier should confirm suitability for the substrate, environment and intended curvature. |
| Application process | Dispense angle, contact point, wipe sequence, wrap control and time before inspection. | Record where the label first contacts and where any bubble, crease or lifting begins. |
Build an adhesion trial that represents production
Use bottles from the intended supply, filled and closed where that changes rigidity or temperature. Apply labels from a production-equivalent roll, then inspect immediately and after the dwell period agreed with the label supplier or project team. Include storage or handling conditions that could reveal edge lift, tunnelling or loss of adhesion. Do not publish a universal dwell time or adhesion value without verified label-manufacturer data and an agreed test method.
Evidence to send
- Bottle material and supplier reference where available.
- Photographs showing panel shape, seams, taper and the intended label position.
- Label face stock, adhesive and liner information from the converter.
- Production temperatures, condensation or cleaning conditions.
- Rejected and acceptable labelled samples, marked with the time after application.
- A video showing the first point of contact and wipe-down if the fault occurs during application.
When to involve the label converter
Ask the converter to confirm the adhesive and face stock for the substrate, curvature, storage and end-use environment. Machine adjustment should not be used to disguise a construction that is unsuitable for the bottle. Equally, a suitable label can still fail if the bottle arrives wet, contaminated or unsupported.
Use the round-bottle placement guide for cylindrical packs, the front and back positioning guide for shaped bottles and the sample-testing checklist to structure the trial.
Review the bottle and label as one application.
Send representative packs and the complete label-roll construction before final machine approval.
