Plastic bottle front and back labelling machine

Plastic bottle stability and shape

Plastic bottles can be light, flexible and shape-variable. They may have tapered panels, curved shoulders or squeezed sides, all of which influence how the machine guides and wipes the label onto the pack.

A stable bottle with clear flat panels is usually simpler to label than a flexible or heavily contoured bottle.

• Confirm if bottles are empty or filled at labelling stage.
• Check whether panels flex under pressure.
• Show any handles, triggers, pumps or closure overhang.

Front and back label registration

For plastic bottles, front and rear labels often need to align with bottle panels, seams or shoulders. The machine should hold the container in a repeatable position and control label feed so both labels land consistently.

Where labels are large or close to edges, small container variations can become visible on the finished pack.

• Send label position drawings if available.
• Measure the usable flat label area.
• Confirm label tolerance and presentation requirements.

Compact vs automatic route

A compact twin side labeller can suit start-up production, smaller batches and lower output. Automatic twin-side systems are more suitable where bottles need to run inline with filling, capping, coding and conveyors.

The best route depends on output, labour, space and changeover frequency.

• Choose compact where space and budget are limited.
• Choose automatic where output and integration matter most.
• Plan changeover if multiple bottle shapes need one machine.

Useful details for a fast quote

A good quote request should include the bottle and label details, but also the line context. This prevents the shortlist from being based only on a generic bottle labeller request.

• Bottle dimensions and pack photos.
• Label dimensions, material and roll direction.
• Target speed and daily/weekly production.
• Any coding, inspection or reject requirements.
