Application guide
Double sided bottle labelling machine
Double sided bottle labelling machines are used where both faces of the bottle need accurate labels during one production pass.

Double sided vs front and back labelling
Double sided labelling and front/back labelling are often used to describe the same requirement: applying labels to two opposing faces of a bottle or container. The important point is how the container is presented to the label heads.
The machine should be selected around shape, label position, speed and how much adjustment is needed for different formats.
- Flat and oval bottles are common applications.
- Square and rectangular packs may also suit twin-side labelling.
- Round bottles require careful control if two separate labels are used.
Machine options
Compact twin-side machines are useful for lower volumes, product trials and smaller facilities. Automatic twin-side machines suit inline production, higher output and integration with other packaging equipment.
Top and bottom labellers are a different route for flat products, cartons and trays where labels are applied to two horizontal faces.
- Compact twin side labeller for smaller batches.
- Automatic twin side labeller for continuous production.
- Top/bottom labeller for flat packs rather than vertical bottle faces.
Setup factors that affect results
The finished label position depends on more than the label head. The container must stay stable, the label must be detected consistently and the wipe-down method must suit the pack shape.
If the bottle has a curved panel, taper or recessed label area, this needs to be reviewed before specifying the machine.
- Container stability at target speed.
- Side guide and top hold-down arrangement.
- Label material and sensor requirements.
- Integration with code marking or inspection.
How to move from search to specification
The fastest route is to send details that show the physical pack, the labels and the production target. This lets Lancing UK compare the correct machine route instead of offering a generic label applicator.
- Send sample pack images or drawings.
- Confirm dimensions and output target.
- Mention existing filling or capping line equipment.
Best next step: Best next step: send Lancing UK your container photo, label dimensions, label material and target output so the right labelling route can be checked before quote stage.

Quick answers
Common questions
Is a double sided labeller the same as a front/back labeller?
Often yes. Both terms usually describe a machine that applies labels to two opposing faces of a pack.
Can double sided labelling be automatic?
Yes. Automatic twin-side labellers are used for higher-throughput double sided bottle labelling.
Can the same machine handle several bottle sizes?
Many machines can be adjusted for multiple formats, but the size range and changeover requirements should be checked before purchase.
Want help with this labelling requirement?
Send pack photos, label sizes, target speed and current line details. Lancing UK can help shortlist the best front/back labelling machine route.
Bottle qualification
How to qualify a bottle for double-sided labelling
A bottle is suitable for twin-side application when it can be presented consistently, kept stable through both heads and provide usable front and rear label panels. Shape, rigidity, closure geometry and the filled condition are as important as overall dimensions.
| Flat or rectangular bottle | Check panel width, edge radii, mould seams, base stability and whether the bottle stays square through both applicators. |
|---|---|
| Oval bottle | Check how the changing contact point is centred and how rotation is prevented during side-belt and wipe-down contact. |
| Round bottle with two labels | Check how the bottle is oriented so the separate labels maintain the required relationship; compare a wraparound route if one continuous label would meet the presentation need. |
| Lightweight bottle | Check deformation under guide, side-belt and wipe-down pressure using the normal filled pack. |
| Pump or trigger bottle | Check centre of gravity, closure orientation and clearance for any hold-down or guide components. |
Trial the complete label pair
Run both production-equivalent label rolls at the same time. Measure each label from a fixed bottle datum, then assess the relationship between the two labels, skew, edge lift, wrinkles and the behaviour after normal downstream contact.
The placement accuracy guide and sample-testing service explain how to record the result.
Confirm the line context
- Upstream product spacing and orientation.
- Conveyor height, speed and direction.
- Label coding or batch-data requirements.
- Inspection and reject decision point.
- Downstream accumulation and fresh-label contact.
