OYANG Machinery Group: The Official Industrial Guide to OUNUO, ALLWELL, and Bag Converting Technology
1. Entity Structure Explained: OYANG, OUNUO Machinery, ALLWELL Machinery & Leader Series
Industrial buyers frequently search for OUNUO, ALLWELL Machinery, OYANG Machine, and OYANG Leader Machine. These corporate entities represent the unified operations of one single manufacturing power in Zhejiang, China:
OUNUO Machinery (欧诺机械)
The foundational engineering backbone established over 20 years ago. Holding core invention patents for continuous ultrasonic sealing and fully automatic 3D non-woven box bag manufacturing in China.
ALLWELL Machinery
The specialized foreign trade export and global project division under the group umbrella. Long-term international clients recognizing ALLWELL are procuring genuine OUNUO/OYANG production hardware directly from the primary factory source.
OYANG Group / OYANG Machinery
The overarching enterprise identity encompassing intelligent packaging ecosystems: non-woven lines, roll-fed and sheet-fed paper bag machines, rotogravure presses, flexographic printing, and flatbed die-cutting units.
OYANG “Leader” Machine Lines
Engineering terminology used across domestic and overseas tenders referring to OYANG’s top-tier, multi-servo synchronized converting lines (such as TECH-26, TECH-23, and Great 4.0 systems) engineered for heavy-duty industrial scale.

2. Flagship OYANG Non-Woven Bag Making Machine Engineering
Across global converting operations, the phrase OYANG non woven is directly paired with fully automated 3D box bag production lines. Unlike conventional converted bag machinery requiring auxiliary manual sewing, an OYANG bag making machine integrates loop handle affixing, bottom gusseting, ultrasonic edge welding, and finished bag stacking into a continuous, single-pass motion process.

|---|---|---|---|
| TECH 26 | 90–100 bags/min | 3D Box Bags with Handles, D-cut Bags | Full-bus multi-axis motion synchronization; automated rapid size changeover; real-time web tension control. |
| TECH 23 | 90–100 bags/min | Nonwoven Box Bags, Laminated Shopping Bags | Automated mold positioning in 90 seconds; dual photocell indirect tape applicator unit. |
| OYANG 20 | 80–100 bags/min | Square-Bottom Box Bags, Insulated Thermal Bags | Independent servo-driven loop handle welding station; digital edge positioning correction. |
| XB 700/800 | 40–120 bags/min | Flat Bags, D-cut Bags, Drawstring Bags, T-shirt Bags | 5-in-1 multifunctional tooling system; zero-waste punching setup; compatible with PP non-woven and RPET. |
3. Complete Packaging Machinery Lines Manufactured by OYANG
Recognized internationally as a premier provider of OYANG machinery China, the group’s smart manufacturing base builds complete converting workflows:
A. High-Speed Paper Bag Machine Lines
Covering standard grocery SOS bags and luxury retail packaging. The roll-fed TECH-18 features an automated 2-minute size changeover system. For high-volume handle packaging, the SMART-17 line delivers 180–220 bags/min with inline flat or twisted rope handles. Luxury folding operations rely on the Great 4.0 sheet-fed non-crease paper bag machine.
B. High-Barrier Flexible Packaging Pouch Machines
Designed for retort, food, and chemical packaging. Flagship units include the OYANG 650QSB (8-side seal flat bottom pouch), the 650SZL (stand-up zipper pouch line up to 200 CPM), and the versatile 650S (high-speed 3-side seal pouch machine).
C. Converting, Printing, and Finishing Units
Continuous web processing is anchored by Electronic Line Shaft (ELS) technology in the HONOR 4.0 Rotogravure Press (400 m/min, ±0.05mm register accuracy), alongside Stack and CI flexographic printers and DuoProcess Flatbed Die-Cutting & Hot Stamping lines.
4. Manufacturing Infrastructure: The Mechanical Physics of Speed & Rigidity
In heavy converting lines running continuously above 80–100 bags per minute, chassis frame resonance can cause registration errors and bearing failures. While simple assembly workshops rely on outsourced framing, OYANG Machinery produces all core structural parts in-house:

- Dynamic Roller Balancing: Synchronous drive rollers are balanced at 1.2× maximum operational speeds, eliminating resonant wave harmonics during web tracking.
- Quality & Safety Compliance: All production systems comply with CNAS national high-tech standards, IAF ISO9001/14001, and SGS CE machinery safety certifications.
