Some labeling projects arrive with a clean brief: one product, one label, standard dimensions. This was not one of those projects.
When our Russian distribution partner came to us with a woven bag labeling requirement, the brief included six different bag variants — different materials, different sizes — all needing a single label applied in a precise position, with a barcode printed on each label at the moment of application, and the entire process running automatically from feed to collection. On top of that, one of the bag variants had perforations that made conventional vacuum-based feeding impossible.
This is the story of how we worked through it.
Our partner on this project is one of Russia's more established packaging equipment distributors — a company of around 30 people focused on mid-to-high-end clients in the food, beverage, and consumer goods sectors. Their customer list includes the kind of names — multinational food and beverage brands — that have zero tolerance for inconsistent packaging quality.
Their core product range covers labeling machines, case sealers, multi-lane packaging lines, and logistics packaging equipment. Before 2022, their sourcing was almost entirely European. We first met at a trade exhibition in Russia in 2019, but the timing was not right. Follow-up through 2020 and 2021 went largely unanswered — they were not looking to change suppliers, and we respected that.
Then 2022 changed the supply landscape for a lot of Russian businesses. They started looking seriously at Chinese manufacturers. They visited our factory in Dongguan twice before placing their first order — thorough due diligence from a company that clearly knew what it was evaluating. Their engineers are experienced with labeling machine commissioning and calibration; when remote support is needed, a video call is usually enough to resolve the issue quickly.
We have been working together since 2024, with four to five orders per year. The majority are custom non-standard labeling machines and our standard YCT-30 plane labeling machine heads.
The end customer's requirement was specific. They were producing woven bags across six different variants — varying in material composition, surface texture, and physical dimensions — and needed a single automated solution that could handle all of them.
The full requirement looked like this:
Requirement | Detail |
Product types | 6 woven bag variants, different materials and sizes |
Label type | Single label per bag, small format |
Coding requirement | Barcode printed on each label during application |
Feeding | Automatic — no manual placement per cycle |
Collection | Automatic — labeled bags collected without operator handling |
Labeling accuracy | Precise position, consistent across all six variants |
Label appearance | Bubble-free, clean adhesion — including on transparent labels |
The transparent label requirement was particularly relevant. Hand-applying transparent labels reliably without air bubbles is genuinely difficult — it is one of those tasks that looks simple until you are doing it at volume. Automating it removes the problem entirely.
There was also a secondary issue that only became apparent after samples arrived.
Once we received physical samples of all six bag variants, we began testing the automatic feed mechanism. Five of the six bags performed as expected. The sixth did not.
One variant had a perforated surface. The standard vacuum-based auto-feed system — which holds and advances products using suction — could not maintain grip on a bag with holes in it. The vacuum simply bled through the perforations, and the bag would not feed reliably.
We could have flagged this as out of scope. We did not.
Instead, we went back to the design and re-evaluated the feeding mechanism specifically for that variant. The solution involved three changes:
Redesigned feed fixture — modified to work with the perforated surface geometry rather than relying solely on vacuum seal
Added air reservoir — to stabilize and buffer the pneumatic pressure across the feed cycle, compensating for the pressure loss through perforations
Upgraded air line diameter — larger bore tubing to maintain consistent airflow volume under the modified load conditions
After these modifications, all six variants fed and labeled reliably. The barcode printing, label placement, and collection all performed to spec.
We sent a test video to the customer before shipment. They confirmed. The machine shipped.
The machine delivered to this project was a custom configuration built on the foundation of our YCT-30 Automatic Plane Labeling Machine, with engineering modifications to meet the specific demands of this application.
Integrated barcode printer — prints variable barcode data onto each label at the moment of application, combining coding and labeling in a single inline pass
Custom automatic feed system — modified pneumatic feed with enlarged air lines and dedicated air reservoir to handle both standard and perforated bag surfaces
Automatic collection — labeled bags exit and are collected without manual handling, completing the fully automated cycle
Multi-variant compatibility — conveyor and label head settings adjustable across all six bag variants without major mechanical changeover
Parameter | Value |
Labeling Accuracy | ±1 mm |
Labeling Speed | 40–80 pcs/min |
Label Length | 6–250 mm |
Label Width | 15–120 mm |
Labeling Surface | Flat, uneven, concave, arc surface |
Power Supply | 220V / 50Hz |
Optional Coding | Ribbon coder / Inkjet printer |
The YCT-30 platform was chosen as the base because its label dispensing mechanism and conveyor synchronization are already engineered for the kind of placement accuracy this application required. Custom-building from scratch would have added time and cost without improving the outcome.
With the modified feed system in place, the machine handled all six woven bag variants in production conditions:
Automatic feed cycle running reliably across all materials, including the perforated variant
Barcode printed and label applied in a single pass per bag
Label placement consistent and accurate across the full run
Transparent labels applied without bubbles or lifting
Labeled bags collected automatically — no operator handling required between feed and collection
Before this machine, the customer's end user was dealing with slow hand labeling, inconsistent label placement, and the persistent problem of air bubbles under transparent labels. None of those issues exist in the automated process.
The distributor's feedback was direct: the customer was very satisfied — with the labeling quality, the throughput improvement, and the fact that the perforated bag problem had been identified and solved before the machine left our facility.
A few things stand out from this project that are worth stating plainly.
Sample testing is not optional for non-standard applications. The perforated bag issue would not have been caught by reviewing drawings or specifications. It only showed up when we ran the actual product through the actual machine. That is why we insist on physical samples before finalizing any custom build.
Solving problems before shipment is the job. Finding the perforated bag issue during testing was not a setback — it was the process working correctly. The alternative would have been the customer discovering it after installation, which is a much more expensive and time-consuming situation for everyone involved.
A strong platform makes custom work faster and more reliable. The YCT-30's core label dispensing and conveyor architecture did not need to be reinvented for this project. The custom engineering was focused on the specific challenge — the feed system — rather than rebuilding the entire machine. That is a meaningful difference in both development time and long-term reliability.
This project is one example of a broader category of labeling challenges that benefit from a custom or semi-custom approach:
Woven bags and flexible packaging — fertilizer bags, feed bags, cement bags, rice bags, and other woven polypropylene packaging requiring product or compliance labels
Perforated or mesh-surface products — any product where standard vacuum feed cannot maintain grip
Multi-variant production lines — operations running several product sizes or formats that need a single machine to handle all variants
Barcode and label combined in one pass — logistics, retail, pharmaceutical, and food applications requiring variable data printing integrated with label application
Transparent label applications — products where bubble-free adhesion is a quality requirement
If your application involves any of these characteristics, a standard off-the-shelf labeling machine may not be the right starting point. A custom configuration based on a proven platform — like the YCT-30 — often delivers better results at lower total cost than adapting a machine that was not designed for your product.

Q: Can you build a labeling machine that handles multiple product variants on the same line?
A: Yes. This project is a direct example — six woven bag variants, different sizes and materials, all handled by one machine. The key is understanding the full range of variants upfront so we can design the feed, conveyor, and label head settings to accommodate all of them. Send us your complete product list and we will assess compatibility.
Q: What if my product has an unusual surface — perforations, mesh, or irregular texture?
A: This is exactly the kind of challenge that requires physical sample testing before finalizing the machine design. In this project, we identified a perforated bag that standard vacuum feed could not handle, and we redesigned the feed system before shipment. We recommend sending samples of all product variants for any non-standard application.
Q: Can the labeling machine print barcodes or variable data at the same time as applying labels?
A: Yes. We integrate barcode printers, ribbon coders, and inkjet printers directly into the labeling machine. In this project, a barcode printer was integrated to print and apply in a single pass. This eliminates a separate printing step and ensures the printed data and label are always aligned.
Q: What is the difference between a standard YCT-30 and a custom configuration?
A: The standard YCT-30 is a production-ready flat labeling machine for books, cartons, boxes, and similar flat products. A custom configuration uses the same core platform — label dispensing head, conveyor, control system — but modifies the feed mechanism, collection system, product fixtures, or coding integration to match a specific application. Custom builds typically start from a detailed review of your product samples and production requirements.
Q: How long does a custom labeling machine project take from inquiry to delivery?
A: Timeline depends on the complexity of the customization. After receiving your product samples and confirming the specification, we provide a project timeline with the quotation. Simple modifications to the standard platform are faster; more complex feed or collection system redesigns take longer. We will give you a realistic schedule upfront.
Q: Do you provide after-sales support for custom machines?
A: Yes. Remote video support is our standard first response for commissioning and troubleshooting questions. For distributors with their own engineering teams — like our Russian partner in this project — most issues are resolved quickly via video call. On-site support is available where required.
Q: What information do you need to start a custom labeling machine project?
A: The most useful starting point is: product dimensions and weight, label size and type (including whether labels are transparent), target labeling speed, any coding or printing requirements, and whether you need automatic feed and/or collection. Physical product samples are required before we finalize the design. Contact us and we will guide you through the process.
Q: Do you work with distributors and resellers outside China?
A: Yes. A significant portion of our business is through distribution partners in Russia, Southeast Asia, the Middle East, South America, and other markets. We support distributors with OEM configuration, technical documentation, and remote engineering assistance. If you are evaluating us as a supply partner, we are happy to discuss how we work with distribution channels.
If you are dealing with a labeling application that standard machines have not been able to solve — unusual product surfaces, multiple variants, integrated coding requirements, or automatic feed and collection — we would like to hear about it.
Send us your product details and samples. We will review the application, identify any challenges early, and come back with a clear technical proposal and quotation.
