DESCRIPTION
The ZONESUN ZS-TB602 is an automatic top-and-bottom labeling machine designed for applying self-adhesive labels to compatible flat products such as boxes, cartons, trays, pouches and other packages with stable flat surfaces.
The upper and lower labeling mechanisms can be adjusted independently, allowing labels to be applied to one side or both sides of the product. The conveyor system and product pressing structure help keep products stable as they pass through the labeling stations.

PLC Touchscreen Control
The PLC touchscreen allows operators to set and adjust working parameters, and the interface language can be customized as needed.
Independent Top and Bottom Labeling
The upper and lower labeling mechanisms apply labels to both sides of flat products and can be controlled separately.
Adjustable Pressing and Label Detection
The vernier knob adjusts the pressing component for compatible products. The label sensor detects labels accurately, with sensitivity adjustment for stable operation.
Adjustable Conveyor System
The conveyor belt transports products steadily, while its width and conveying speed can be adjusted for compatible products.

Why Choose the ZS-TB602?
- Top and bottom labeling in one pass: Suitable for products that require labels on both flat faces without turning the package manually.
- Independent labeling heads: The top and bottom applicators can be adjusted separately to match different label positions and product heights.
- Adjustable conveyor and pressing structure: Helps stabilize compatible products and maintain consistent label placement during continuous production.
- PLC touchscreen control: Simplifies adjustment of conveyor speed, label dispensing and other operating parameters.
- Expandable configuration: Depending on the selected version, the line can be configured with additional paging, coding or print-and-apply functions.
Best-Suited Products
The ZS-TB602 is best suited to products with stable, relatively flat upper and lower surfaces, such as cartons, boxes, rigid trays, flat pouches and similar packages.
Standard Labeling vs Print-and-Apply Configuration
| Configuration | Best For | Key Difference |
|---|---|---|
| Standard Machine | Pre-printed self-adhesive labels | Applies labels that have already been printed |
| Print-and-Apply with Paging Feeder | Applications that need variable information printed before labeling | Adds printing and automatic product separation/feeding functions |
Before Ordering, Please Confirm
- Product length, width and height
- Product weight and whether the surface is rigid or flexible
- Top label size and application position
- Bottom label size and application position
- Label roll inner diameter and outer diameter, if already determined
- Required production speed
- Whether coding or variable-data printing is required
- Whether an automatic paging/feeding system is needed
- Voltage: 110V or 220V
Important: Labeling speed and accuracy depend on product stability, label size, label material, conveyor speed and final machine configuration. Sending product and label samples is recommended for customized projects.
Frequently Asked Questions
Can the machine apply only a top label or only a bottom label?
Yes. The upper and lower labeling mechanisms can be controlled independently, so one side can be used when required.
Can it label soft pouches?
Some pouches may be suitable, but soft or unstable bags can shift during labeling. The product should be tested to confirm whether additional pressing or guiding is required.
Can the machine print dates or barcodes?
Printing depends on the selected configuration. A standard labeler applies pre-printed labels, while a print-and-apply version can be configured for variable information such as dates, batch numbers or barcodes.
Can it handle different carton sizes?
Yes, within the machine's adjustment range. Significant product-size changes may require guide, sensor or labeling-head adjustments.
Can it be integrated into an existing packaging line?
Yes. Conveyor height, speed matching and signal connection should be confirmed with the upstream and downstream equipment before production.
Need Help Confirming Your Labeling Application?
Send us your product dimensions, product photos, label size, label position and required speed. If variable printing is needed, also send the required print content. We can recommend the appropriate ZS-TB602 configuration. Use the chat window on this page to contact ZONESUN.
