UBL automatic case packers deliver stable, high-precision fully automatic carton packing for diverse finished goods. Compatible with bottles, pouches, small inner cartons, cans, jars and plastic bags, we supply customized packing systems for food, beverage, pharmaceutical and daily chemical manufacturers.
When filling and primary packaging run faster than manual packing, finished products quickly accumulate at the end of the line, reducing overall production efficiency and delaying shipments.
Packing requires multiple operators, ongoing training and shift management. As production increases, labor expenses continue to grow while profitability declines.
Manual packing often results in incorrect counts, poor product alignment, damaged cartons and inconsistent case quality, increasing customer complaints and transportation losses.
Continuous lifting, bending and repetitive movements lead to operator fatigue, workplace injuries and lower productivity throughout each shift.
Manual packing creates a fixed production ceiling. Expanding output often means hiring more workers instead of improving efficiency.
Because manual packing speed varies by operator and shift, production schedules become difficult to predict, affecting on-time delivery performance.

Powered by a Siemens programmable logic controller (PLC) with high-speed data processing and strong anti-interference performance. The system delivers 99.5% operational reliability, supports real-time fault self-diagnosis, and ensures stable non-stop 24/7 production.
All core motions (grabbing, pushing, lifting, positioning) are driven by high-precision servo motors. It achieves ±0.15mm repeat positioning accuracy with smooth, gentle product handling, keeping product damage rate below 0.05‰ — ideal for fragile food containers, glass jars and soft pouches.
Reinforced carbon steel main frame with precision welding and anti-corrosion powder coating; all food-contact parts are made of 304 stainless steel. The rigid structure eliminates vibration at high running speeds, extends service life, and fully meets food industry hygiene requirements.
Integrates carton erecting, product packing and carton sealing into a single workstation. It saves over 40% of factory floor space compared with separate machines, removes intermediate conveying steps, and lowers total end-of-line investment cost.
Color touch screen human-machine interface with multi-language support. Features one-click parameter setting, real-time production data monitoring and clear fault code prompts. Even untrained operators can master it quickly, reducing skill requirements for frontline workers.
Full servo motor drive for stable, low-noise, high-speed running, packing speed 1–6 cartons per minute.
Intuitive touchscreen HMI saves multiple box presets for quick size changeover.
Modular design allows front-end connection with box folding machines, back-end docking with printing labeling machines and palletizing robots.
Horizontal side push packing mode avoids vertical extrusion damage to fragile inner boxes; adjustable 5–10mm gap between goods and cartons to protect finished products. Supports layered stacking of multiple inner boxes for one-time carton filling.
Upstream docks with automatic carton erectors; downstream connects with carton sealers, weight check rejectors, real-time printing labeling machines and palletizing robots. Suitable for food, cosmetics, daily goods, hardware and e-commerce warehouse mass packaging.
Full servo push mechanism for smooth operation, packing speed 1–2 cartons/min. Touchscreen stores multiple preset carton sizes for fast size changeover, reducing line downtime. Heavy-duty machine frame runs stably for long continuous shifts.
Designed for 5-layer corrugated shipping cartons. All dimensions can be customized according to customers’ actual box specifications, professional technical team provides on-site size evaluation service.
Dual servo gripper manipulators perform stable multi-layer product grabbing and vertical loading; adjustable 5–10mm clearance prevents extrusion damage to fragile goods. High flexibility for irregular inner boxes and bulk commodity packing.
Packing speed adjustable from 1–6 cartons/min, freely matched with different upstream production line output. Touchscreen stores multiple size presets for one-click switching, greatly shortening model change time.
Upstream connects with automatic carton erectors; downstream links carton sealers, weight check rejectors, real-time printing labeling machines and palletizing robots. Widely used in food, cosmetics, daily necessities, hardware and e-commerce warehouse packaging.
Suitable for 5-layer corrugated shipping cartons. All internal/external dimensions can be customized according to customers’ actual box specifications. Heavy-duty welded frame ensures long-term continuous stable operation.
Choosing the right automatic case packing machine is more than comparing speeds and specifications. Manufacturers often need to evaluate product compatibility, carton styles, production capacity, line integration, labor savings, maintenance requirements, and long-term return on investment before making a purchasing decision.
To help manufacturers make informed decisions, UBL has compiled this comprehensive FAQ based on years of packaging automation experience and real-world customer projects. Whether you’re planning your first automation upgrade or expanding an existing production line, this guide answers the questions most frequently asked by production managers, engineers, and procurement teams.
The questions below are organized according to the typical buying journey—from understanding how case packing machines work, to selecting the right model, integrating it into your production line, evaluating operating costs, and learning about UBL’s engineering and support services.
An automatic case packing machine (or case packer) is end-of-line packaging equipment that automatically loads finished products, inner boxes or bulk items into outer corrugated shipping cartons. It replaces repetitive manual carton loading work, ensures consistent packing quality, and integrates with upstream production lines and downstream sealing/palletizing equipment to build a fully unmanned packaging workflow. Common configurations include top-load robotic gripping models and side-load horizontal push models.
| Dimension | Top Load (Robotic Gripping) Case Packer | Side Load (Horizontal Push) Case Packer |
|---|---|---|
| Loading method | Vertical top-down grabbing by servo grippers | Horizontal side push into cartons |
| Best for | Multi-layer stacked inner boxes, irregular products, tray sets | Flat single-layer products, row-arranged items |
| Packing speed | 1–6 cartons per minute, adjustable | 1–2 cartons per minute |
| Investment cost | Higher, with more flexible application | Lower, ideal for simple single-format packing |
| Typical model | UBL HL-ZX01 | UBL HL-ZX02 |
Yes. All UBL case packers are equipped with a touchscreen HMI that stores multiple sets of product and carton size presets. Operators can switch between different SKUs by calling saved parameters, without replacing mechanical parts or making major adjustments. The machine supports flexible production for multi-SKU small-batch orders.
Yes. UBL case packers adopt a modular design with standard conveyor interfaces and signal communication protocols. They can be seamlessly connected to your existing production conveyor lines, with no need for large-scale reconstruction of your current layout. We provide custom inlet/outlet conveyor solutions to match different line heights and directions.
Yes. The UBL HL-ZX01 top-load case packer is built with a dual servo robotic gripping mechanism for pick-and-place packing. The gripper arms pick products from the feeding conveyor precisely, arrange them in preset multi-layer layouts, and place them gently into cartons. This structure avoids extrusion damage to fragile products and supports flexible stacking schemes for different box combinations.
Yes. After case sealing, packed cartons can be conveyed via accumulating conveyors to an automatic palletizing robot. The whole end-of-line workflow — case erecting, product packing, carton sealing and pallet stacking — can be fully automated with zero manual intervention. UBL provides integrated turnkey solutions covering all end-of-line packaging equipment.
