Two Side Labeling Machine
We manufacture Two Side Labeling Machines at our factory in Foshan, China, for flat, oval, and square bottles that require front and back labels. Send us your bottle dimensions, label size, and target output, and our engineers will specify the right machine for your application.
How Our Two Side Labeling Machines Work
Bottles move onto the conveyor and are spaced so each one reaches the labeling station individually. On the Two Side Labeling Machine, two applicator heads are positioned opposite each other, one on each side of the conveyor. A sensor detects the bottle, both heads operate from the same position signal, and pressing belts hold the container square while the front and back labels are applied together.
The key to accurate two-side labeling is preventing the bottle from rotating. Unlike a round bottle labeler, this machine must keep the container stable so the front and back labels stay aligned. Side belts and centring guides control bottle position as it passes through the machine, which is why flat and oval bottles are generally easier to run than round containers.

What You Get on a Popper Two Side Labeler
These are specific build features included in the Two Side Labeling Machines we ship, not just a general list of what two-side labelers can do.
- Front and Back Registration: Both labeling heads operate from the same bottle-position signal, helping the front and back labels align with each other rather than independently to the conveyor.
- Rotation Control: Side pressing belts and centring guides keep the bottle square through the labeling station, reducing rotation that can cause the front and back labels to drift out of alignment.
- Clear Label Sensing: Photoelectric sensing is configured for your label stock, including transparent film where standard sensors may not detect the label gap correctly.
- Change Parts Included: Guide rails and belt spacing are supplied for each bottle format you plan to run, not only the first one.
- Recipe Storage: Bottle and label-pair settings can be saved as recipes, making changeovers a selection process instead of a full recalibration.
- Tested on Your Bottle: We test your bottle and labels at the specified output before shipment and provide the test result.

Applications of the Two Side Labeling Machine
A Two Side Labeling Machine is selected mainly by bottle shape and whether the front and back labels need to align accurately with each other. The industry primarily determines the label material, documentation, and compliance requirements for the application.
| Shape | How it runs | Notes |
|---|---|---|
Flat and Oval |
Best fit for a Two Side Labeling Machine |
Flat faces help prevent bottle rotation, keeping front and back labels accurately aligned. |
Square and Rectangular |
Runs well |
Guide spacing must be set accurately so corners pass smoothly without catching. |
Round |
Possible with orientation control |
Round bottles can rotate between the two labeling heads. If front and back labels must register, bottle orientation is needed at the infeed. |
Tapered or Shouldered |
Depends on the parallel section |
Labels need to sit on the parallel face of the container, which can limit the usable label height. |
Three factors determine whether the front and back labels stay accurately aligned on a Two Side Labeling Machine, and all three are configured during the build.
- Position Signal: Both labeling heads operate from the same bottle-detection signal rather than triggering independently.
- Rotation Control: Side belts and centring guides keep the bottle square and stable as it passes through the labeling station.
- Label Feed Registration: Servo-driven label feeding maintains consistent placement as the label reel diameter decreases during production.

We provide integration support for the Two Side Labeling Machine as part of a complete filling, capping, labeling, and packaging line. Our team can help match conveyor height, bottle handling, line speed, and control signals with your existing or new equipment so the full line runs smoothly.
After labeling, products can move directly into secondary packaging. For retail-ready protection and grouped packaging, a shrink wrap packaging machine can be integrated as part of the final production workflow.
Label Options, Round Bottles, and When to Choose a Different Labeling Machine
Label Options, Round Bottles, and When a Different Machine Fits Better
Standard paper and film labels run on a Two Side Labeling Machine without special setup. Transparent labels require photoelectric sensing tuned to the label gap because standard sensors can read clear material as a continuous web. Share your label material at the enquiry stage so we can configure the correct sensing during the build. For glass containers, bottle weight and surface finish affect handling; see our guide to labeling machines for glass bottles.
Round Bottles on a Two Side Machine
Round bottles can run on a Two Side Labeling Machine, but they rotate more easily than flat or oval containers. If a bottle turns between the two applicator heads, the front and back labels can move out of registration. Where two labels must align accurately, we can integrate a bottle orientation system into the infeed so every bottle reaches the labeling station in the same starting position. If the labels do not need to register with each other, a round bottle labeling machine is usually the simpler and more economical option.
When a Different Machine Is the Better Fit
A Two Side Labeling Machine is designed for applying front and back labels to upright containers. If you only need one label on one face, a single side labeling machine is usually the more suitable option. If labels need to be applied to the upper and lower faces of a flat product, use a top and bottom labeling machine. You can compare the full range on our labeling machine page.
Building a Complete Bottle Line
A Two Side Labeling Machine typically runs after filling and capping because a closed bottle is stable enough to stay square as it passes through the labeling station. We can also supply the upstream equipment, including our liquid filling machine and bottle filling machine range for free-flowing products, and a sauce filling machine for thicker products. Before labeling, bottles can pass through our capping machines, including servo capping machines where controlled cap torque is important. After labeling, our packaging machines can handle secondary and end-of-line packing.

Yes. The Two Side Labeling Machine can be configured for transparent labels by using a sensor designed to detect clear label stock. Standard photoelectric sensors may read transparent material as a continuous web and fail to detect the gap correctly. For more details, see our guide to transparent label machines.
Front and back label misalignment is usually caused by the bottle rotating between the two applicator heads or by side-belt tension being set for a different bottle width. On a Two Side Labeling Machine, correct bottle control is essential for keeping both labels registered. For more causes and fixes, see our labeling machine troubleshooting guide.
