The YCT-51 Automatic Side Labeling Machine is a heavy-duty label applicator designed to place self-adhesive labels on the side surfaces of large flat products. It addresses a distinct requirement: applying labels accurately to the narrow vertical side edge of items such as books, binders, cartons, and large-format packaging boxes.
Built by Dongguan Yucheng Machinery Technology Co., Ltd. (YCTAUTO), this machine supports product dimensions from L: 40–400 mm × W: 40–200 mm × H: 0.2–150 mm — making it one of the widest-range side labelers in the YCTAUTO lineup. The extended height range of up to 150 mm (customizable) accommodates the tall cartons and thick binders that are beyond the reach of many standard flat-surface labeling machines.
At 40–120 pcs/min, the YCT-51 is suited for both medium-volume specialty operations and high-throughput fulfillment environments. A modifiable labeling head addresses uneven, concave, and arc surfaces for specialty packaging. Optional ribbon coding and inkjet printing modules integrate date and batch marking directly into the labeling pass.
High-Speed Side Label Application — Operates at 40–120 pcs/min, making the YCT-51 one of the fastest side labelers in its class and suitable for demanding production environments where throughput is a priority.
±1 mm Placement Accuracy — Consistent label positioning on every product side surface, ensuring barcode readability, brand uniformity, and compliance label alignment across long production runs.
Extended Product Height Range — Accommodates products up to 150 mm in height (customizable), enabling side labeling of tall cartons, thick binders, and deep packaging boxes that exceed the capacity of standard flat-surface labelers.
Large Product Footprint Compatibility — Handles products up to 400 mm long and 200 mm wide, designed for large flat products commonly encountered in publishing, office supply, and carton packaging.
Flexible Label Dimensions — Accepts labels from 6 mm to 250 mm in length and 15 mm to 120 mm in width, covering spine labels, barcode strips, certification stickers, and brand labels used on side surfaces.
Irregular & Arc Surface Capability — Modifiable labeling head design allows the YCT-51 to apply labels to uneven, concave, and curved side surfaces — extending its use to premium packaging, branded retail boxes, and specialty formats.
Optional Ribbon Coding & Inkjet Printing — Integrated hot-stamp or inkjet modules print dates and batch/lot numbers during application, enabling in-line regulatory compliance without a separate coding station.
Heavy-Duty Industrial Construction — At 300 kg with 1740 W power consumption, the YCT-51 is built for sustained high-speed production duty with a machine footprint of 3100 mm × 1300 mm × 1560 mm suited to industrial floor installation.

The YCT-51 addresses side-labeling requirements across a diverse range of industries and product types:
Publishing & Stationery — Book spines, binder spine labels, notebook edge labels, document folder identification strips, and file archiving labels
Retail & E-Commerce Packaging — Carton side barcodes, parcel side identification labels, and outer carton marking for distribution and fulfillment operations
Food & Beverage — Large food carton side labels, beverage multipack side labeling, dry goods packaging edge stickers, and date code labeling on outer cartons
Electronics & Industrial — Component carton side markings, appliance packaging labels, and asset identification stickers on large packaging boxes
Cosmetics & Personal Care — Gift set outer box spine labeling, cosmetics carton side brand labels, and promotional sticker application on retail display boxes
Chemical & Logistics — Chemical carton side hazard labels, logistics side marking, and compliance label application on outer packaging for regulated categories
Purpose-Built for Large Flat Products — The YCT-51's extended product range and heavy-duty construction are engineered for large carton and flat-product side labeling that lighter-duty machines cannot reliably serve.
Rigorous Pre-Shipment Testing — Every machine is fully assembled and production-tested at our Dongguan facility before shipment, ensuring a calibrated, ready-to-run system.
Custom Engineering Support — We configure conveyor width, labeling head position, and guide systems to your specific layout. OEM and private-label options are available for resellers and systems integrators.
Global Technical Support — Our engineering team provides English-language remote commissioning support, operation manuals, and spare-parts service to customers worldwide.
Integrated Line Solutions — Yucheng supplies filling, capping, conveying, and labeling equipment under one roof for full packaging line design from a single partner.
Q: How does the YCT-51 differ from a top-surface labeler?
A: The YCT-51 labels the vertical side surface of flat products — such as a book spine or carton edge — rather than the horizontal top face. Its labeling head, guide system, and conveyor are all optimized for side-surface application on large flat items.
Q: Can the YCT-51 label products with curved or irregular side surfaces?
A: Yes. With a modified labeling head (available as a configuration option), the YCT-51 can apply labels to uneven, concave, and arc side surfaces. Please describe your product geometry when requesting a quote so we can specify the correct head configuration.
Q: What coding options are available?
A: The YCT-51 supports optional ribbon (hot-stamp) coding for date and lot code printing, and optional inkjet printing for variable data and QR codes. Both options integrate directly into the labeling pass, requiring no separate coding step.
Q: What is the MOQ and standard delivery lead time?
A: Minimum order is 1 unit. Standard machines ship within 7–12 business days. Custom-configured orders typically require 15–25 business days. We confirm timelines at the time of order.
Q: Can the YCT-51 be connected to my existing production line?
A: Yes. The YCT-51 is designed for in-line installation and can be synchronized with upstream and downstream conveyor equipment. Share your line layout, conveyor speed, and product flow direction with our team for a detailed integration review.
Send us your product dimensions, label specifications, target speed, and line layout, and our team will provide a configuration recommendation and competitive quotation.
