An OYANG non woven bag making machine is an automated eco-packaging converting line engineered to process PP spunbond non-woven fabric and RPET rolls into 3D box bags, D-cut flat bags, and loop handle carry bags. Integrating continuous multi-axis servo synchronization, auto-tracking ultrasonic thermal bonding, and digital recipe management, OYANG converting platforms sustain production speeds of up to 100 bags per minute with an automated 90-second mold changeover system that eliminates downtime during short-run order switching.
In high-speed eco-packaging manufacturing, traditional conversion setups face three operational bottlenecks: excessive downtime during dimensional changeovers, high hot-melt adhesive consumption, and mechanical frame deflection that destabilizes ultrasonic horn welding above 60 bags/min.
Ultrasonic bonding relies on high-frequency acoustic friction to melt thermoplastic fibers at microscopic contact points. In continuous conversion lines, if chassis wall panels vibrate by even ±0.05 mm, the dynamic horn pressure fluctuates erratically, triggering joint crystallization failures or fabric burn-through.
OYANG replaces open-loop mechanics with a closed-loop digital acoustic architecture synchronized directly to the line’s multi-axis servo drives:
Generators monitor horn thermal rise in real time, maintaining resonance within a tight ±10 Hz window to eliminate acoustic impedance mismatch at 100 bags/min.
Continuous power regulation adjusts horn amplitude dynamically across 30–120 GSM fabric variations, delivering hermetic side-gusset bonding without pinholes.
Milled titanium sonotrodes ensure uniform energy transfer across cross-folded handle seams, consistently exceeding 150 N tensile pull resistance.
By machining all structural wallboards on Japanese MAZAK CNC lines to flatness tolerances within ≤ 0.015 mm, mechanical harmonic vibration is eliminated, holding fabric scrap rates strictly under 1.5%.
Equipment selection depends upon planned output volumes, target bag configurations, and degree of downstream automation. Below is the technical specification matrix across OYANG’s flagship 3D box bag series:
| Technical Parameter | OYANG SMART 19 | OYANG TECH 23 (Flagship) | OYANG TECH 26 |
|---|---|---|---|
| Max Production Speed | 80 – 100 bags/min | 90 – 100 bags/min | 90 – 100 bags/min |
| Mold Changeover Time | Manual / Assisted | 90 Seconds (Fully Automatic) | 90 Seconds (Fully Automatic) |
| Servo Drive System | Multi-axis Bus Control | 50-Axis Full Servo Control | Advanced Multi-Axis Servo |
| Gluing Technology | Direct Tape Applicator | Indirect Tape Applicator (Patented) | Indirect Tape Applicator (Patented) |
| Labor Saving Integration | Standard Collection Table | Robotic Arm + Auto-Bundling | Robotic Arm + Auto-Bundling |
A non-woven box bag making machine is a high-speed mechatronic assembly operating under continuous cyclic stresses. Within OYANG’s 130,000㎡ smart manufacturing base, all load-bearing chassis elements are machined in climate-controlled centers to ensure dynamic alignment across 15+ years of multi-shift operation.
Conventional non-woven box bag machines apply double-sided adhesive tape continuously across the full side-gusset width. OYANG’s patented Indirect Tape Applicator (integrated on the OYANG 18 and TECH 23) applies adhesive intermittently, saving one side-width length of tape per bag.
For a standard bag with a 100 mm side gusset, this eliminates $0.0007 USD in adhesive cost per unit. Under industrial capacity runs, the cost savings accumulate rapidly:
The OYANG TECH 23 is engineered for large-scale packaging operations supplying retail, takeaway food, and consumer goods markets. It operates stably at 90–100 bags/min with automated dimensional changeovers.

For heavy-duty retail shopping totes and industrial carrier packaging, the OYANG TECH 26 expands the maximum bag forming width to 540 mm while maintaining 100 bags/min velocity and servo-driven changeover automation.

On traditional mechanical machines, changing bag specifications takes 30 to 60 minutes of manual mechanical adjustments. On the OYANG TECH 23 and TECH 26 models, the integrated 50-axis servo system enables a fully automatic, one-key mold changeover in under 90 seconds via the touch screen.
The primary raw material is PP (Polypropylene) spunbond nonwoven fabric rolls. For high-end laminated bags, you will need BOPP film laminated nonwoven fabric. OYANG also supports eco-friendly RPET (Recycled Polyethylene Terephthalate) fabrics, which are 100% recyclable and up to 5 times more durable than standard nonwoven bags.
